SYNOPSIS
/opt/FJSVswsrp/bin/swsrpsetvol [-n] [-u] [-Xvtoc] [-Xgroup groupName] originalVolumeName replicaVolumeName
/opt/FJSVswsrp/bin/swsrpsetvol [-n] [-u] [-Xvtoc] -o (ORG|REP|BOTH) [-Xgroup groupName] originalVolumeName replicaVolumeName
/opt/FJSVswsrp/bin/swsrpsetvol [-h serverName] [-n] [-u] [-Xvtoc] [-Xgroup groupName] originalVolumeName replicaVolumeName
/opt/FJSVswsrp/bin/swsrpsetvol [-h serverName] [-n] [-u] -o (ORG|REP|BOTH) [-Xvtoc] [-Xgroup groupName] originalVolumeName replicaVolumeName
DESCRIPTION
This command sets the replication source volumes and replication destination volumes that are used in a replication operation. Execute this command to declare that the replication operation is performed using the specified replication volumes.
When using the Storage Cluster Continuous Copy Function, configure the replication source and replication destination volume information that are commonly used by the Primary Storage and Secondary Storage.
OPTIONS
When executing on the Management Server, specify the name of the target Managed Server.
When executing on the target Managed server, it is not necessary to specify this option.
For the server name, accurately specify the same letters, including upper and lower case, as the server name displayed with the stgxfwcmdispsrv command.
Specifies the direction of copying.
If this option is specified, copying is performed only in the direction from replication source volume to a replication destination volume. Copying from a replication destination volume to a replication source volume is prohibited.
If this option is omitted, copying between the replication source and replication destination volumes is bidirectional.
When performing the server-to-server replication, specify the operation server(s) authorized to manage replication.
Specify one of the following for this operand:
ORG : Sets the replication source server as the operation server.
REP : Sets the replication destination server as the operation server.
BOTH : Sets both the copy-source server and copy-destination server as operation servers.
When BOTH has been specified, all commands can be executed from either the replication source server or the replication destination server.
When ORG or REP was specified, the non-operation server cannot issue the following commands:
However, in the following cases, the non-operation server can issue the above commands.
When specifying the -d option with the swsrpdelvol command.
When specifying the -c option with the swsrpcancel command.
When specifying the -b option with the swsrpcancel command.
If this option is omitted, replication volume information cannot be set when the sizes of the replication source volume and replication destination volume are different.
When this option is specified, the sizes of the replication source volume and replication destination volume are not checked. Use this option when volume sizes are different (for example, for replication between different OSs).
When the volume sizes of the replication source volume and replication destination volume are different, copying is performed as follows:
The address at which copying starts is the first sector of the replication destination volume.
The copy data size is the size of the smaller volume.
Therefore, ensure that the size of the copy destination volume is the same size or larger than the size of the copy source volume.
This option cannot be used for SDX object logical volumes (PRIMECLUSTER GD Snapshot linkage function).
Specifies that the copy source and copy destination volumes are registered in a group.
If the specified group does not exist, a new group is created. Otherwise, the specified copy source and copy destination volumes are added to an existing group.
The characters that can be used for the group name are single-byte alphanumeric characters, the hyphens (-), underscore (_), number sign (#) and period (.). The first character must be a single-byte alphanumeric character. Up to 64 characters can be used.
If this option is omitted, Solaris slices that include VTOC cannot be set as replication source volumes or replication destination volumes.
Specification of this option avoids checking to see whether or not replication source and replication destination volumes include VTOC.
This option is specified for the following replication source and replication destination volumes:
Under Solaris, VTOC-labeled disk slices that contain VTOC
Under Solaris, a VTOC-labeled disk second slice that indicates the entire disk
Under Solaris, an EFI-labeled disk MPxIO device that indicates the entire disk
This option is ignored if it is set for volumes other than the above.
OPERANDS
Specifies a replication source volume name.
For the volume names of other servers, use the format "Volume-Name@Managed-Server-Name".
Specifies the AdvancedCopy Manager device name for the Volume-Name.
Specifies a replication destination volume name.
For the volume names of other servers, use the format "Volume-Name@Managed-Server-Name".
Specifies the AdvancedCopy Manager device name for the Volume-Name.
EXIT STATUS
=0: Completed successfully
>0: Terminated abnormally
EXAMPLES
Set replication volume information by specifying volume "/dev/dsk/c1t2d0s3" of Managed Server "SRC-SV" as the replication source volume and volume "/dev/dsk/c1t2d0s3" of Managed Server "TARG-SV" as the replication destination volume. In addition, specify one-way copying for the copy direction and specify the replication source server "SRC-SV" as the operation server. The example below shows the command executed on "SRC-SV":
# /opt/FJSVswsrp/bin/swsrpsetvol -u -o ORG /dev/dsk/c1t2d0s3 /dev/dsk/c1t2d0s3@TARG-SV swsrpsetvol completed #
When the same settings are made from "TARG-SV", the example is as follows (be careful with the volume name):
# /opt/FJSVswsrp/bin/swsrpsetvol -u -o ORG /dev/dsk/c1t2d0s3@SRC-SV /dev/dsk/c1t2d0s3 swsrpsetvol completed #
NOTES
Replication volume information cannot be set if:
Replication volume information has already been set.
The specified replication source volume and replication destination volume are already set as the replication destination volume and the replication source volume respectively.
The -n option is not specified when the sizes of the replication source volume and the replication destination volume are different.
Two volumes that have the same box information (ie, box identifier, OLU number, EXTENT start position, and EXTENT size) as the box information of the specified two volumes have already been set as replication volumes.
The replication destination volume has been registered as a backup volume by the backup management function.
The replication source volume has been registered as a backup volume by the backup management function and bi-directional copying is specified as a replication volume attribute.
The specified replication destination volume and replication source volume are volumes belonging to other servers (at least one volume must be a volume on the local server).
If the replication source volume and the replication destination volume are located on another ETERNUS Disk storage system, the remote copy function of the ETERNUS Disk storage system is not correctly set.
Communication with the Management Server fails.
Communication with a destination server fails for server-to-server replication.
The IP version registered on AdvancedCopy Manager differs between the replication source server and the replication destination server.
When the replication source volume or the replication destination is VxVM logical volume that is not supprted by the replication management function.
(For details on the logical volume that can be supported by the replication management, refer to "1.4.1 Normal Devices").
The license for the ETERNUS Disk storage system that contains the specified replication source/target volume is one of the following:
The license is not registered in the license management function.
The license is expired.
When the specified replication source and replication destination volumes are neither of the following combinations:
Both the replication source volume and the replication destination volume are TFOV.
Both the replication source volume and the replication destination volume are non-TFOV.
The specified replication source and destination volumes belong to different TFO groups.
The specified replication source and destination volumes are in the failover or in the failback state.
Note the following points about creating copy source volumes and copy destination volumes under Solaris:
When creating multiple volumes (slices) on the same disk, volume areas must not overlap.
If slices contain VTOC, check the notes in "Slices that contain VTOC" under "General notes".
When you change physical information on volumes (ie, partition size, drive letter, and box information on ETERNUS Disk storage system device using such functions as an OS management tool (format command etc ) or ETERNUS Web GUI provided by ETERNUS Disk storage system, PRIMECLUSTER GD, you need to reset the registered replication volume information associated with the changed volumes, by following these steps:
Delete the replication volume information using the swsrpdelvol command.
Refer to "Add/Reload Device" in the Web Console Guide to reload the configuration. Otherwise the stgxfwcmsetdev command is executed in a Management Server.
Reset the replication volume information using the swsrpsetvol command.
When you use a replication destination volume by mounting after a replication volume is created in another partition, the size of the replication destination volume must exactly match the size of the replication destination volume to the byte. If you do not use a replication destination volume (for example, when you need copy data, you restore it to the replication source volume and then use it), the size of the replication destination volume can be larger than the size of the replication source volume.
Group configurations cannot be made in the group configuration conditions are not met.
When SDX objects of PRIMECLUSTER GD are used: Refer to "Configuration and Conditions of Unsupported SDX Objects", and "10.1.7 Notes on SDX Object Operations (Replication Management)".
This command cannot be executed while any of the following commands are running:

NOTES
Replication volume information cannot be deleted if:
The specified replication source volume and the replication destination volume are not set as replication volumes.
The copy processing (synchronization processing and snapshot processing) is performed between replication volumes.
For server-to-server replication, the Managed Server that executed the command is not the operation server of the replication volume.
Communication with a Management Server fails.
For server-to-server replication, communication with a destination server fails.
However, OPC sessions are neither confirmed nor cancelled by execution in emergency operation mode. If an OPC session is in the error suspended state, then unmanaged sessions remain. In this event, ETERNUS Web GUI must be used to cancel these sessions.
If a logical volume of VxVM is deleted, or if changes are made to its configuration that cannot be supported by AdvancedCopy Manager, replica volume information cannot be deleted. In this case, perform processing of a or b shown below.
Specify the -e option and execute the command, after checking that an Advanced Copy is not processing in the replica volume to be deleted (if an Advanced Copy is running, stop the Advanced Copy processing in the target ETERNUS Disk storage system).
Execute the command after re-creating the logical volume with a configuration that AdvancedCopy Manager can support, or after returning the logical volume configuration to its original state.
When SDX objects of PRIMECLUSTER GD are used: Refer to "Configuration and Conditions of Unsupported SDX Objects", and "10.1.7 Notes on SDX Object Operations (Replication Management)".

NOTES
The device name on a box to display information can be specified as -Xaltpath.
Settings for dedicated REC buffers must be made in advance.
Change the settings while there are no Consistency mode sessions in either the ACTIVE or ERROR SUSPEND state.
It takes a short time for changes to buffer settings to take effect, during which time the REC buffer becomes unusable. Do not perform REC operations during this time.
This command cannot be executed while any of the following commands are running:
The REC buffer settings cannot be changed by using TFOV.
