Assign Hot Spare
The [Assign Hot Spare] function registers a hot spare, which enables automatic data copy
(Rebuild) in the background when a disk failure occurs.
Hot spare is a disk that is available as a substitute for a failed disk.
There are two types of hot spare as follows:
• Global Hot Spare
Hot spare used by all the RAID groups
• Dedicated Hot Spare
Hot spare used by the dedicated RAID group (one specific RAID group)
A "Global Hot Spare" is a shared hot spare prepared in case a failure occurs in a RAID group.
When preparing hot spares for a specific RAID group, register them as "Dedicated Hot Spare".
Note the following items when adding a hot spare:
• A system disk (Slot#0 to Slot#1 of the controller enclosure) cannot be
specified as a hot spare.
• A hot spare that substitutes for a failed disk must have the same or a
larger capacity than the data disk. If the hot spare capacity is smaller
than the data disk, the disk does not work as the hot spare.
• Generally, a hot spare can be installed in any slot, with the exception of
system disk installation locations.
• When switching in a hot spare for a failed disk, a hot spare with the
same capacity as the failed disk will be used first. If such a hot spare
does not exist, a large capacity hot spare will be used (when there are
multiple numbers of such disks, the smallest capacity hot spare among
them is used). Note that a Global Hot Spare is used in this situation.
• When you replace a failed disk, the data is copied back from the hot
spare that is substituting for the failed disk, and the hot spare disk then
returns to a spare disk.
• When a mix of SAS disks, Nearline SAS disks, and SSDs are installed
together in the ETERNUS DX60/DX80/DX90, hot spare of each type is
required. Install the hot spare that has the same capacity as the largest
capacity disks of the same type installed in the ETERNUS DX60/DX80/
DX90.

Logical Device Expansion
The [Logical Device Expansion] function expands the capacity of an existing RAID group by adding new disks or changing RAID levels.
Normally, volume expansion requires adding RAID groups. This method requires multiple disks
to be installed (used). However, this function can add disks to the existing RAID group in units of
one disk. This enables capacity expansion of RAID groups with smaller number of disk expansion.
This function can be performed with taking over data in the disks.

Set Eco-mode Schedule
Eco-mode is a function that is specifically designed to reduce the power consumption that is
characteristic of Massive Arrays of Idle Disks (MAID).
Eco-mode saves power by managing the scheduled operation times of specified disks and stopping the motors of disks during periods when they are not required.
The scheduled operation times can be set for each RAID group and for operations such as
backing up.
The [Set Eco-mode Schedule] provides the following functions:
● Eco-mode General Setting
Enables or disables the Eco-mode setting for ETERNUS DX60/DX80/DX90.
● Eco-mode Schedule Setting
Specifies the disk operating time (term for activating disk motor constantly) as an Eco-mode
schedule.
● Apply Eco-mode Schedule
Applies the created Eco-mode schedule for each RAID group.
Disk operation time varies depending on the Eco-mode schedule settings and disk access.
A disk is spun up even if it is outside of disk operation time in the following conditions:
• If an access occurs while a motor is stopped
The disk is immediately spun up and access proceeds normally after one to three minutes.
• If a disk is activated more than a set amount of times in a day
A state of increased access frequency is assumed and the Eco-mode will cease stopping the
disk motor.

LUN concatenation adds new space for volumes and expands the volume capacity that can be
used from the server.
This function enables the use of free area in the RAID group, and solves capacity shortages.
This function obtains the area to be used for capacity expansion from unused areas in an existing RAID group. LUN concatenation creates a new volume with the obtained area, and concatenates these volumes to be used as a large capacity volume.
Concatenation of multiple free areas from different RAID groups is possible. Also, concatenation
is possible even if the RAID levels of the groups are different.
Up to 16 volumes can be concatenated. The maximum volume capacity after concatenation is

Advanced Copy Management
Advanced Copy Management provides the following functions.
• Setup Snap Data Pool
• Manage Copy Session
• Register Copy License
• Modify Copy Parameters
• Modify EC/OPC Priority
• Modify Copy Table Size
• Set Copy Path
• Modify Port Mode (*1)
• Modify REC Multiplicity (*1)
• Modify REC Buffer (*1)
*1:
This function is available when using the ETERNUS DX90.
■ Advanced Copy function
Advanced Copy is a function used to quickly copy data (volume) to another volume in the same
device, at any given point in time. By using the copy destination volume, it is possible to backup
data without suspending operations.
The copy function of ETERNUS DX60/DX80/DX90 can be used by the following methods:
• Copy in units of volumes using GUI or CLI command
• Obtaining snapshots of volumes by using the Windows Volume Shadow Copy Service (VSS)
function
• Obtaining backup and replication that is associated with operation by using the ETERNUS SF
AdvancedCopy Manager (ACM)
The copy function of ETERNUS DX60/DX80/DX90 creates a snapshot of the selected volume.
Copy usage (such as backup and replication) and the procedure for copy vary depending on the
OS and software to be used. Refer to the manuals for each OS and software for details.
■ Type of Advanced Copy
Equivalent Copy (EC) function (*2) and One Point Copy (OPC) function (*3) are the available
Advanced Copy functions.
• EC
EC is used when copying large volumes, or when processing time can be estimated easily.
• OPC
OPC is used when it is difficult to estimate the backup time.
*2:
*3:
In this manual, "EC function" indicates EC and Remote Equivalent Copy (REC).
In this manual, "OPC function" indicates OPC, QuickOPC, and SnapOPC+.
GUI provides various settings and status displays for the Advanced Copy
function.
However, only SnapOPC+ sessions can be created using GUI.
139
P2X0-0700-07ENZ0
Each function is described below.
● EC (Mirror Breaking method)
EC makes a mirror copy of the copy source to the copy destination beforehand and then
keeping it up to date while it is needed, at which time the mirror relationship is "broken" to
reveal the desired copy.
The updated data in the copy source will be reflected to the copy destination volume after
completing the operation. After mirror is established, all writes are also duplicated.

*4: After mirror is established, all writes are also duplicated.
Also, for ETERNUS DX90, the following function is available.
● REC
EC among different devices on the site is called REC. REC is different from EC, EC performs
Advanced Copy within the same device, whereas REC copies data between different devices.
Advanced Copy between different devices is called Remote Advanced Copy. Remote
Advanced Copy can be used to replicate data for making backups and for testing. Note that
REC uses the same copy method as EC.

P2X0-0700-07ENZ0
By creating a REC connection to an off-site device using network lines, IP lines and fiber
optical lines, for data transfer, REC can be performed between remote locations. Remote

REC has two transmission modes, asynchronous transmission mode and synchronous
transmission mode. Which mode is selected should be based on the line type and the
influence on access to the transaction volumes:
- Synchronous transmission mode
The write completion signal for a write request by the server is only returned after the write
to the copy source and the copy write to the copy destination have both completed.
However, synchronizing the data copy with the copy source write guarantees the contents
of the copy source and copy destination at the time of completion.
This method has a significant effect on write accesses from the server, and so is only
recommended for device-to-device copies between sites where the communications lag is
small.
- Asynchronous transmission mode
Write completion signals to write requests from the server are returned as soon as the
write to the copy source has been done, without waiting for the data to be copied to the
copy destination.
Copying the data to the copy destination asynchronously with the write allows the copy to
be performed without affecting the write performance of the server/copy source pair.
This method is recommended for device-to-device copies between devices at remote
sites.
This method is used for remote disaster backups.
Asynchronous mode has two sub-modes, Stack mode and Consistency mode.
Which should be selected will depend on the pattern of usage. There is also a Through
mode that is used to finalize data transfer for the other two modes.
• Stack mode
Only updated block positions are recorded before returning the completion signal to the
server, so waiting-for-response effects on the server are small. Actual transfer of the
recorded blocks can be performed by an independent transfer engine.
This mode is mainly used for remote backup.
This mode can be used even when the available line bandwidth is small, but a large
amount of untransferred data can accumulate as a result.
141
P2X0-0700-07ENZ0
• Consistency mode
This mode guarantees the sequential transmission of updates to the destination device
in the same order as the writes occurred. This is useful when mirroring databases and
copies of multiple connected areas.
This mode uses a part of the cache memory as a transfer buffer. The blocks being
copied are "saved" into a send buffer and then transferred to the receive buffer, from
which they are then "extracted".
When using the Concurrent Suspend function, the transfer mode does not need to be
changed to the Through mode.
• Through mode
This mode is not used for normal transfers, but rather to transfer all as-yetuntransferred data when stopping or suspending the Consistency mode or Stack mode.
● OPC (Background Copy method)
The OPC function logically copies all data from the copy source to the copy destination in the
same device, when the host requests the operation. The ETERNUS DX60/DX80/DX90
immediately returns an OPC completion response to the copy request. This function then
allows prompt access to both the original and copied data while the actual physical copying
proceeds in the background. Unlike EC, the updated data in the copy source will not be
reflected to the copy destination volume after completing the operation.

The following functions relating to the OPC are also available.
● QuickOPC
Just as for OPC, QuickOPC copies all the data in the copy source volume at the initialphysical copy. After the initial-physical copy has completed, only updated data needs to be
copied hereafter. Because it reduces the copy volume and realizes high-speed backup,
QuickOPC is recommended for backing up a large-scale database.

● SnapOPC+
SnapOPC+ manages data by allocating OPC data and sessions that form generations, and
copies updated data only to the latest generation.
SnapOPC+ manages generations of differences between updated data as modification
history. It enables copying to be performed with less physical capacity. Maximum number of
generations varies depending on the ETERNUS models and software.
SnapOPC+ is recommended for backing up less updated volumes such as the file server.

P2X0-0700-07ENZ0
SnapOPC+ uses the unique volume (Snap Data Volume: SDV) as a copy destination.
Also, a setting pool area for SDV (Snap Data Pool Volume), to continue the copy session
even when the amount of update data exceeds the SDV capacity, is available.
- SDV (Snap Data Volume)
SDV is an area used as a copy destination for SnapOPC+.
Only one copy destination can be specified per SDV.
Refer to "5.3.1 Create Volume" (page 111) for detailed procedure to create SDV.
- SDP (Snap Data Pool)
SDP is a standby storage area to continue sessions even when the amount of update data
exceeds the SDV capacity. It enables the storage area to be supplied from SDP to SDV as
required. This continues the copy session even when the amount of update data exceeds
the SDV capacity.
Note that SDP is configured by a unique volume Snap Data Pool Volume (SDPV).
Creating SDPV enables SDP.
- SDPV (Snap Data Pool Volume)
SDPV is a unique volume for SDP.
Created SDPV is automatically added to the SDP.
- SDPE (Snap Data Pool Element)
SDPE is a unit of SDP that is managed in the ETERNUS DX60/DX80/DX90.
Once the copy destination SDV capacity runs out, SDPEs are supplied from SDP to SDV
and the storage area is automatically expanded. Supplied storage (SDPE) returns to SDP
after the copy session complete.
Note that SDPE capacity is fixed to 1GB.

another SnapOPC+ copy session may be created.
The ETERNUS DX60/DX80/DX90 returns the SDPE when accepting a SnapOPC+ session deletion request.

■ Preparations for the Advanced Copy function
This section describes how to prepare for using the Advanced Copy function and copy session
management.
● Advanced preparation
The following preparations are required when using Advanced Copy functions.
- License registration
Register a license for using the Advanced Copy function.
If a license is not registered, up to eight copy sessions can be performed.
When an Advanced Copy feature is purchased, refer to "5.4.3
Register Copy License" (page 155) to register the license.
- Copy destination volume creation
Create a physical volume according to the amount of updated data in the copy source volume.
When performing SnapOPC+, create SDV and SDP.
Refer to "5.3.1 Create Volume" (page 111) and "5.4.1 Setup Snap Data Pool" (page 146)
for details.
• The RAID configuration of the copy source and copy destination
can be different.
• The copy source and copy destination volume encryption status
must match.
- Copy table size setting
Set the copy table size depending on the capacity of the copy target volume.
Refer to "5.4.6 Modify Copy Table Size" (page 160).
- Copy priority setting
Specify the copy priority in the ETERNUS DX60/DX80/DX90.
Refer to "5.4.5 Modify EC/OPC Priority" (page 158).
When performing SnapOPC+, the following preparations are also required.
- Copy parameter setting
Specify the threshold to report the shortage of SDP volume capacity during the copy
operation.
Refer to "5.4.4 Modify Copy Parameters" (page 156).
When performing REC, the following preparations are also required.
- Port mode setting
Specify a threshold for notification when a shortage of SDP volume capacity occurs during
the copy operation.
Refer to "5.4.8 Modify Port Mode" (page 184).
- Copy path setting
Set the Copy path information between devices.
Refer to "5.4.7 Set Copy Path" (page 164).
- REC buffer setting
Set the transfer buffer setting when performing REC in asynchronous consistency mode.
Refer to "5.4.10 Modify REC Buffer" (page 188).
145
P2X0-0700-07ENZ0
- REC multiplicity setting
Set the multiplicity used for performing REC. This setting is required when the connection
type in the [Set Copy Path] is "Remote".
Refer to "5.4.9 Modify REC Multiplicity" (page 186).
● Copy session management
After preparation for Advanced Copy is complete, create a copy session to start copying volumes. During operation, check the status of the copy sessions and delete unnecessary copy
sessions.
- Copy session creation
Create a copy session via Windows Volume Shadow Copy Service (VSS) / ETERNUS SF
AdvancedCopy Manager (ACM).
Note that GUI can create SnapOPC+ session only.
Refer to "5.4.2 Manage Copy Session" (page 152).
GUI cannot create copy sessions other than SnapOPC+ sessions. Create copy sessions
via VSS/ACM.
- Copy session check
Check the status of each copy session using the [Advanced Copy Status] screen. Refer to
"4.4 Advanced Copy Status" (page 61).
For REC sessions, checking copy path and buffer status are also available.
Refer to "4.5 Advanced Copy Path Status" (page 63) and "4.6 REC Buffer Status" (page
65).
- Copy session deletion
Delete unnecessary copy sessions.
Data in the copy destination volume loses its meaning (becomes undefined).
For SnapOPC+, SDPs used by the deleted copy sessions are released.
Refer to "5.4.2 Manage Copy Session" (page 152).
In principle, use GUI to delete copy sessions created in GUI.
Deleting copy sessions created by software other than GUI, such as
Windows Volume Shadow Copy Service (VSS) and ETERNUS SF
AdvancedCopy Manager (ACM), is not allowed. However, if deleting
from VSS/ACM cannot be performed, use GUI to delete copy sessions.
5.4.1
Setup Snap Data Pool
This section describes how to set a Snap Data Pool (SDP), the pool area for SDV.

• Only one RAID group is registered in the ETERNUS DX60/DX80/
DX90, and Logical Device Expansion is in progress in the RAID
group
• The status of all the RAID groups is not "Available", or "Present"
- When no SDPV is created in the ETERNUS DX60/DX80/DX90, and
the maximum number of volumes for each model is already
registered.
147
P2X0-0700-07ENZ0
• Unlike other volumes, SDPV cannot be created by "5.3.1 Create
Volume" (page 111) menu or deleted by "5.3.2 Delete Volume" (page
114) menu.
• While SDPV can be created in any level RAID group, it is recommended
that the same RAID group configuration be used for all SDPVs created.
• The maximum capacity of SDP is 32TB for ETERNUS DX60, and 64TB
for ETERNUS DX80/DX90.
• Allocated space (SDPE) to SDV from the SDPV is released in the
following conditions:
- When deleting the SnapOPC+ session:
If one SnapOPC+ session is deleted, all the SnapOPC+ sessions
started earlier than that session are also deleted. The space used in
the SDV for the stopped generation is released.
- When the SnapOPC+ session turns to "Error" status:
If one SnapOPC+ session status turns to Error, the status for all the
SnapOPC+ sessions started earlier than that session also change to
Error. The space used in the SDV for the generation in Error status is
released.
The procedure to create SDPV is as follows:
Procedure

→ Snap Data Pool setting is started. The SDPV is created in the selected RAID group.
After SDPV is created, new volume is automatically formatted.
End of procedure
Delete SDPV
This function deletes the registered SDPV.
There are two methods for deletion: "Reserve Delete" and "Force Delete".
• Reserve Delete
If the target SDPV is being used, the SDPV is scheduled for deletion. SDPV that is scheduled
for deletion will be deleted after the Advanced Copy session completes (when the usage of
SDPV becomes "0").
• Force Delete
The selected SDPV is forcibly deleted even if the copy session is under progress. However,
SDPV that is scheduled for deletion cannot be deleted. Wait for the scheduled deletion to
occur.
Up to 128 SDPVs can be deleted at the same time.

P2X0-0700-07ENZ0
5.4.4
Modify Copy Parameters
The [Modify Copy Parameters] function sets the parameters to enable automatic reporting and
processing when a SDP capacity shortage occurs during the SnapOPC+ operation.
If the copy source data exceeds the physical capacity of copy destination (and when the free
SDP does not exist), an error occurs in the relevant copy session and other older copy sessions.
This function prevents stopping copy session when the capacity shortage occurs.
There are two methods for notification; E-mail and SNMP Trap. ETERNUS DX60/DX80/DX90
reports the notification using the method specified in the [Setup Event Notification] screen. Select
whether to notify when a SDP capacity shortage occurs. When notifying, select the notification
method in advance.
The procedure to modify copy parameters is as follows:
Procedure
1
Click the [Modify Copy Parameters] under the [Advanced Copy Management]
→ The [Modify Copy Parameters] screen appears.

Select the threshold for SDP usage ratio.
The magnitude relation for each value must be in the following order:
Threshold for Policy Level 1 < Threshold for Policy Level 2 < Threshold for Policy Level 3
• Policy Level 1 (Informational) of Snap Data Pool
- Threshold (%)
Specify the usage ratio of SDP between 1 and 97.
If the copy source data exceeds the specified value, the ETERNUS DX60/DX80/
DX90 notifies that effect.
• Policy Level 2 (Warning) of Snap Data Pool
- Threshold (%)
• Policy Level 3 (Error) of Snap Data Pool
- Threshold (%)
156
P2X0-0700-07ENZ0
• When reporting automatically if the threshold is exceeded, set the
notification method using the method specified in the "6.4.7 Setup
Event Notification" (page 245) in advance.
• Notification of the shortage of SDP capacity is sent only once for
each policy level. Even if the threshold is satisfied again within the
24 hours from the first notification, the ETERNUS DX60/DX80/
DX90 does not report that effect. After 24 hours has passed, the
device sends a notification again.
• If the threshold for multiple policies is satisfied at the same time,
the ETERNUS DX60/DX80/DX90 notifies of the highest policy
level.
3
→ The specified copy parameters are registered.
End of procedure
157
P2X0-0700-07ENZ0
5.4.5
Modify EC/OPC Priority
The [Modify EC/OPC Priority] function is used to set the copy speed when using EC (EC and
REC(*1)) and OPC (OPC, QuickOPC, and SnapOPC+).
The EC/OPC speed is usually set in consideration of the host's I/O load and copy processing
load. The set speed of EC/OPC becomes effective when the next session starts.
Select the EC/OPC priority from the following:
• Automatic Priority
This mode changes the EC/OPC priority automatically in response to the operating load
status.
• High Priority
This mode operates by making maximum use of internal resources.
This mode greatly affects host access performance, thus should not be used during normal
operation. Use when the operation load is low.
• Low Priority
This is a mode in which the influence on host access is reduced to a minimum.
Set this mode when using EC and/or OPC during operation.
*1:
The REC priority is specified using the [Modify REC Multiplicity] function, however, setting values
specified here are available in the following conditions:
• When the connection type is "Direct"
• When the REC multiplicity is not specified
Refer to "5.4.7 Set Copy Path" (page 164) for connection type settings.
Refer to "5.4.9 Modify REC Multiplicity" (page 186) for REC multiplicity settings.
The procedure to modify EC/OPC priority is as follows:
Procedure
1
Click the [Modify EC/OPC Priority] under the [Advanced Copy Management]
→ The [Modify EC/OPC Priority] screen appears.
158
P2X0-0700-07ENZ0
2
Specify the following item, and click the [Set] button.
• EC/OPC Priority
Select the EC/OPC speed from "Automatic Priority", "High Priority", or "Low Priority".
3
→ The selected EC/OPC priority is set.
End of procedure
159
P2X0-0700-07ENZ0
5.4.6
Modify Copy Table Size
The [Modify Copy Table Size] function is used to set the control table size on the CM cache
memory installed in the ETERNUS DX60/DX80/DX90, which is used by the device firmware.
When an EC (EC or REC), or OPC (OPC, QuickOPC, or SnapOPC+) function is in use, this control table (hereafter: copy table) is used as the bitmap area that manages the progress of the
copy.
Changed settings will be effective when the next session is started.
• When the copy table size is equal to 0MB, copy functions cannot be
used. Note that the initial (factory default) copy table size setting is 0MB.
• Make sure to stop the copy session before reducing the copy table size.
• The copy session status can be checked from the [Advanced Copy
Status] screen on the [Status] tab.
Copy table size (table size) and resolution vary according to the copy capacity and number of
sessions that are operated at the same time.
(1) Resolution
This value determines the amount of data each bit in the copy bitmap represents.
The allowed resolution settings of "1 (standard)", "2", "4", "8", and "16" respectively give
8KB, 16KB, 32KB, 64KB, and 128KB regions of data per bitmap bit. The same value is
used for all the copy sessions in the ETERNUS DX60/DX80/DX90.
The resolution should be set as small as possible to reduce the internal process overhead.
Set "1" if possible.
(2) Copy Table Size
A dedicated memory area is required for Advanced Copy management and is allocated as
a table size.
The table size and resolution settings are determined by the copy capacity and the
number of sessions (volumes) that will be run simultaneously. The following shows the
table sizing formula.
S (Table size) [MB] =
S1 (EC/REC table size) [MB]
+ S2 (OPC table size without OPC Restoration) [MB]
+ S3 (OPC table size with OPC Restoration) [MB]
+ S4 (QuickOPC table size without OPC Restoration) [MB]
+ S5 (QuickOPC table size with OPC Restoration) [MB]
+ S6 (SnapOPC+ table size) [MB]
160
P2X0-0700-07ENZ0
• Round the derived value up to the next multiple of 8 to obtain the correct
setting for the copy table size.
• A copy table of the appropriate size (as derived above) is created in
each controller (CM0/CM1).
• If the total table size value (S) exceeds the maximum size allowed,
adjust the resolution (M) upward until the maximum table size is no
longer exceeded. The resolution should be kept as small as possible.
• Maximum allowed table sizes are as follows:
ETERNUS DX60: 64MB
ETERNUS DX80/DX90: 128MB
• Allowance should be made for possible future increases in the copy
capacity when calculating the EC/OPC/QuickOPC/SnapOPC+ table
size.
• If the resolution is changed during an existing copy session, the table
sizing formula described in this section is not applied.
• The same bitmap ratio (M) value must be used by both the copy source
device and copy destination device. If the bitmap ratio settings for the
copy source and copy destination devices are different, REC cannot be
performed. Note that the table sizes (S) do not need to be identical.
When different recommended bitmap ratios are calculated for of the
copy source and copy destination devices, use whichever bitmap ratio is
larger for both devices, recalculating the table size setting for the device
whose original bitmap ratio was lower.

For EC, OPC, QuickOPC, and REC copy sources, the copy capacity is the total capacity of all
volumes (slices or partitions) in the ETERNUS DX60/DX80/DX90 that are defined as copy sources.
For REC copy destinations, the copy capacity is the total capacity of all the volumes (slices or partitions) in the ETERNUS DX90 that are defined as copy destinations.
For multi-copy sessions, the copy capacity is the total capacity of multi-copy source volumes (slices or
partitions), multiplied by the number of multi-copy destinations for each copy source.
[Example] Calculating capacity of multi-copy sessions:
Copy area in the copy source volume A: 200MB, Number of multi-copy destination: 4
Copy area in the copy source volume B: 500MB, Number of multi-copy destination: 8
B
A
200 × 4 + 500 × 8 = 4800MB.
Add this 4,800MB to the copy capacity C1, C2, or C4, depending on the copy type. (For EC and REC,
add the value to C1. For OPC, add the value to C2. For QuickOPC, add the value to C4.)
When using EC or REC, add the number of multi-copy sessions to obtain N1. When using OPC, add
the number of multi-copy sessions to obtain N2. When using QuickOPC, add the number of multi-copy
sessions to obtain N4. In this example, use 12 (= 4 + 8) for N1, N2, or N4, depending on the copy
type.
When using multi-copy and executing OPC Restoration from the copy destination, select one copy
destination and apply the above formula. (For QuickOPC, the QuickOPC destination should be used.)
Other copy destinations are calculated as for normal multi-copy.
162
P2X0-0700-07ENZ0
*2:
For SnapOPC+, copy capacity indicates the total capacity of SnapOPC+ copy source volumes (slices
or partitions) × number of generations in a device.
[Example] Calculating capacity of SnapOPC+ sessions:
SnapOPC+ copy area in the copy source volume C: 200MB, Number of SnapOPC+ generations: 8
SnapOPC+ copy area in the copy source volume D: 500MB, Number of SnapOPC+ generations: 4
D
C
Capacity of SnapOPC+ copy source = 200 [MB] × 8 + 500 [MB] × 4 = 3600 [MB]
3600 [MB] derived above is the copy source capacity C6.
*3:
In the example above, use 12 (= 8 + 4) for N6, the number of SnapOPC+ sessions (total number of
generations).
The procedure to set the copy table size is as follows:
Procedure

(RA)).
• CA
Used for connecting to the host.
• RA
Used for performing REC.
• The [Modify Port Mode] function is available when using ETERNUS
DX90.
• When changing the port mode of a live port from "CA" to "RA", it is necessary to stop the host access connected to the CA Port to be changed.
To change the mode of a newly added port, it is not necessary to stop
host access.
• When changing the port mode of a live port from "RA" to "CA", it is necessary to check that there is no session in the RA Port to be changed. If

Modify REC Multiplicity
The [Modify REC Multiplicity] function sets the REC multiplicity.
REC multiplicity is the line speed parameter for each copy path.
By specifying the appropriate multiplicity, the device controls the I/O of the line being used for
remote connection, and uses lines efficiently.
• This function is available when using ETERNUS DX90.
• Normally, do not change REC multiplicity and make sure to use the
default ("Auto") setting.
• If no destination device information is registered, this function is not
available.
• Each line device may not perform with the REC multiplicity specified
with this function. Setting values are used as information for using a line
efficiently.
• Suspend the session status between the devices in the following conditions. In other cases, there is no need to suspend the copy session.
- When changing the connection method ("Direct" or "Remote")
- When measuring round trip time again
• The REC multiplicity can be specified when selecting "Remote" for the
specification mode in "5.4.7 Set Copy Path" (page 164).
• In the following conditions, EC/OPC priorities specified in "5.4.5 Modify
EC/OPC Priority" (page 158) is used instead of REC multiplicity:
- When the connection method is "Direct"
- When no REC multiplicity is set
• Specified REC multiplicity is enabled immediately
The procedure to set REC multiplicity is as follows:
Procedure
1
Click the [Modify REC Multiplicity] under the [Advanced Copy Management]
→ The [Modify REC Multiplicity] screen appears.

When selecting "Manual" for the specification mode, specify the REC multiplicity
between 1 and 256 using numeral characters.
When the round trip time is not obtained, "***" is displayed. To display the recommended multiplicity, obtaining round trip time using
the [Set Copy Path] function is required.
3
→ The REC multiplicity is set.
End of procedure
187
P2X0-0700-07ENZ0
5.4.10
Modify REC Buffer
The [Modify REC Buffer] function sets the transfer buffer for copying data via the REC buffer in
asynchronous Consistency mode.
Copy via REC buffer stores multiple REC session I/Os in the REC buffer for a certain period of
time, and copies them in blocks. This enables mirroring of whole database and securing copy
speed when performing REC between remote locations, several thousand kilometers away from
the source device.
Consistency mode stores data in the large capacity of REC transfer buffer for a certain period of
time, and copies them at one time. Note that one REC buffer cannot be used bi-directionally
(both of sending and receiving). When performing REC bi-directionally, also set the REC buffers
in the opposite direction.
REC buffer usage can also be checked using the ETERNUS SF AdvancedCopy Manager
(ACM).
• This function is available when using the ETERNUS DX90.
• REC buffer must be specified for both devices performing REC. Note
that one REC buffer is unidirectional. When transferring data bi-directionally, both of sending and receiving REC buffers must be specified in
the each device.
• Up to four REC buffers can be specified. A maximum of 512MB REC
buffers in total can be secured.
• When changing or deleting REC buffers, suspend the sessions using
the target REC buffers.
• When copying data via REC buffer, REC buffer settings are required in
both of copy source and copy destination devices. Make the REC buffer
size the same for the devices of the copy source and destination. The
size will be adjusted to whichever is smaller.
• If no destination device and/or copy path are set, REC buffer setting is
not available.
Refer to "5.4 Advanced Copy Management" (page 139) for details about
REC data transfer method and mode.
The procedure for setting REC buffer is as follows:
Procedure
1
Click the [Modify REC Buffer] under the [Advanced Copy Management] menu on
→ The [Modify REC Buffer] screen appears.
188
P2X0-0700-07ENZ0
2
• Usage
Select the usage of REC buffer from "Send" or "Receive".
If the REC buffer is not set, "Unused" is displayed.
When the target REC buffer is not used, select "Unused".
• Remote Box ID
Select the Box ID for the remote device.
A ’- (hyphen)’ is displayed when the usage of REC buffer is "Unused".
If the REC path information is deleted, "???" is displayed. Select
"Unused" for REC buffer usage or select a new remote Box ID.
• Size (MB)
Select the REC buffer size (MB) from the following:
- 128
- 256
- 512
REC buffer size is secured from the cache memory. When using
broadband connections or responding to temporary line transfer
delays, a larger REC buffer size is needed.
• Forwarding Interval (sec)
Select the forwarding interval (second) to transfer the data stored in the REC buffer to
the destination device from the following:
- 1
- 2
- 4
- 8
- 15
- 30
- 45
- 60
- 75
- 90
- 105
- 120
A long interval will reduce the Host I/O overhead, but increases
the amount of data susceptible to loss in the event of disaster.
189
P2X0-0700-07ENZ0
• Monitoring Time (min)
Select from 0 to 15 (minutes) for the REC buffer monitoring time. The recommended
value is "5 (minutes)".
When the REC Buffer has large amounts of data to be stored and is in a high-load
state, the time required for I/O responses to the server delays for the specified time in
the "HALT Wait Timer" (from the server's viewpoint, the ETERNUS DX60/DX80/DX90
seems to be delaying its response).
Once the delay state has continued for longer than the watch time setting (this item), all
REC Consistency mode sessions that are currently transferring data are HALTed to
allow priority processing of the server responses. If "0 (minutes)" is set, monitoring is
disabled.
• HALT Wait Timer (sec)
Select from 0 to 15 (seconds) for the HALT Wait Timer. Although the recommended
value is "15 (seconds)", select the appropriate value considering the effect on the system.
HALT Wait Timer is the maximum no-response time for which host I/O responses may
be delayed in order to prioritize data transfers from the REC Buffer when it is in a highload state.
When the set time is exceeded, responses for the Host I/O is restarted, but the REC
session is automatically HALTed. If "0 (seconds)" is set, the Host I/O always takes priority when this occurs and the copy session is HALTed immediately.
An error screen appears in the following conditions:
• Clicking the [Set] button without changing any setting values
• When two or more REC buffers have the same usage and the
same remote Box ID
• The total size of four REC buffers exceeds 512MB
• Clicking the [Set] button when any of the remote Box ID is "???"
190
P2X0-0700-07ENZ0
Make sure to set the same REC buffer information (size, forwarding
interval, monitoring time, and HALT wait timer) for copy source and
copy destination devices.

Setup SNMP Agent
Simple Network Management Protocol (SNMP) is a standard protocol used by the network management of TCP/IP. This standard protocol is used to monitor the equipment connected with the
network, via the network.
SNMP is comprised of a monitoring part (SNMP Manager) and a monitored part (SNMP Agent).
Information to be transferred with SNMP is defined in the Management Information Base (MIB), a
database installed in the SNMP Agent. The equipment that configures the network is managed
by transferring parameters between the SNMP Manager and SNMP Agent.
SNMP uses the following five commands to request, respond to, and provide the management
information between SNMP Manager and SNMP Agent.
When an ETERNUS DX60/DX80/DX90 uses the SNMP Agent
environment, it is necessary to install software in the SNMP Manager.
The procedure to set an SNMP Agent is as follows:

Host I/F Management
Host I/F Management provides the following host connection related functions.
• Set Port Parameters
• Setup Host
• Setup Host Response
• Modify Reset Group
ETERNUS DX60/DX80/DX90 can relate the Logical Unit Number (LUN) of the host to volumes in
the device, and set or limit the volume that is recognized from the host.
Host Affinity relates the LUN and volume to each interface port connected in the host.
● When using Host Affinity function
The [Host I/F Management] is used when connecting multiple servers via a switch.
The server recognizes the affinity group specified for each Host Bus Adapter (HBA).
By restricting the volumes can be recognized from each server, security improvement is
expected.

Modify Reset Group
The [Modify Reset Group] sets the reset group to switch the path for some servers.
A reset group is a setting that groups multiple ports that will be reset. If a host is unable to access
the volumes in a port, this function releases the volumes reserved by the inaccessible port to the
ports in the specified reset group, without affecting other ports. The reset group setting sets this
range for each port.
When a 2-port configuration server (including duplication) using the same volume cannot be
accessed, it is possible to access the ETERNUS DX60/DX80/DX90 from the opposite port
(standby side). The port for the paths that access the same volume must be grouped in the same
reset group. Even if the server is different, ports accessing the same volume must be set in the
same reset group.
• When a port is shared by multiple servers using the "5.3.10 Configure
LUN Mapping" (page 131) function, only volumes that are included in
the LUN mapping assigned to the target server in the Host Affinity
setting are subject to release.
• One port cannot be registered in multiple reset groups.
• When using the ETERNUS DX90, ports whose port mode is "RA" cannot be selected as a grouping target port.

Appendix C The Maximum Number of Concurrent
Volume Formats
The maximum number of concurrent volume formats (*1) differs depending on RAID levels, volume capacity, and the model. If 80 or more 2TB disks have been installed in the ETERNUS
DX80/DX90, the maximum number of concurrent volume formats may be exceeded. In this case,
an error message appears.
Use the following procedure to check the maximum number of concurrent volume formats.
Calculate the corresponding value for each formatting volume. When the total of corresponding
values for all the formatting volumes is smaller than the maximum value, concurrent volume formats are available.
*1:
Includes the volume format that is performed automatically when creating a new volume.
Procedure
1
Calculate the corresponding value for each formatting volume.
Use the following formula to calculate the value for each volume to be formatted.
Corresponding Value for each Volume = Volume Capacity (MB) / Coefficient
Volume capacity:
The capacity of the volume to be formatted (MB).
Coefficient
The following table shows the coefficient for each RAID level where the target volume
is registered.

Compare the total of the corresponding values and the maximum number of
concurrent volume formats.
If the total of the corresponding values is smaller than the maximum value, concurrent
volume formats are available.
Total of Corresponding Values < Maximum Value
The total of corresponding values:
Add up the corresponding values for each volume.
The maximum value of concurrent volume formats:
The following table shows the maximum value of concurrent volume formats for each
model.
The maximum value: 33,554,432
End of procedure
The following table shows an example when formatting volumes in the RAID5(5D+1P) in which
the capacity is 9,331,200MB.
