NAME
swsrpsetvol - sets the replication source volumes and replication destination volumes
SYNOPSIS
/opt/FJSVswsrp/bin/swsrpsetvol [-n] [-u] [-Xvtoc] [-Xgroup Group-Name] Original-Volume-Name Replica-Volume-Name
/opt/FJSVswsrp/bin/swsrpsetvol [-n] [-u] [-Xvtoc] -o (ORG|REP|BOTH) [-Xgroup Group-Name] Original-Volume-Name Replica-Volume-Name
/opt/FJSVswsrp/bin/swsrpsetvol -h Server-Name [-n] [-u] [-Xvtoc] [-Xgroup Group-Name] Original-Volume-Name Replica-Volume-Name
/opt/FJSVswsrp/bin/swsrpsetvol -h Server-Name [-n] [-u] -o (ORG|REP|BOTH) [-Xvtoc] [-Xgroup Group-Name] Original-Volume-Name Replica-Volume-Name
DESCRIPTION
This command sets the replication source volumes and replication destination volumes that will be used in a replication operation. Execute this command to declare that the replication operation will performed using the specified replication volumes.
OPTIONS
Specifies the name of a Storage Server that is subject to the replication operation. This option is valid only on a Storage Management Server.
If this option is omitted, the Storage Server on which the command is entered will be the target of the processing.
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.
Specifies the operation server.
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.
On the server that is not specified as the operation server, only the following commands can be executed for a replication volume:
swsrpvolinfo (Replication volume information display command)
swsrpcancel (Replication cancellation command) (The forcible stop option is required.)
Specifying BOTH in the operand enables the execution of all commands on both the copy-source server and copy-destination server. Note that the BOTH option is usable when the versions of both servers are 11.0/V11.0L10 or later.
This option is valid only for replication between servers.
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 (GDS Snapshot function linkage function).
Specifies that the copy source and copy destination volumes will be 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 minus sign (-), 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 not specified, 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
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@Storage-Server-Name."
Specifies an 1.5 Managing a Device on AdvancedCopy Manager for the volume name.
Specifies a replication destination volume name.
For the volume names of other servers, use the format "Volume-Name@Storage-Server-Name."
Specifies an 1.5 Managing a Device on AdvancedCopy Manager for the volume name.
EXIT STATUS
=0:Completed successfully
>0:Terminated abnormally
EXAMPLES
Set replication volume information by specifying volume/dev/dsk/c1t2d0s3 of Storage Server SRC-SV as the replication source volume and volume /dev/dsk/c1t2d0s3 of Storage 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 cabinet information (ie, box identifier, OLU number, EXTENT start position, and EXTENT size) as the cabinet 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 systems, the remote copy function of the ETERNUS disk storage systems is not correctly set.
Communication with the Storage Management Server fails.
Communication with a destination server fails for replication between servers.
When the replication source volume and the replication destination volume are a replication management function and a logical volume of unsupported VxVM
(For details on the logical volume that can be supported by the replication management,
refer to "1.5.1 Normal devices").
The replication source volume or the replication destination volume exists in ETERNUS DX60, ETERNUS DX80 or ETERNUS DX90, and the license of its ETERNUS disk storage system is not registered in the License Manager.
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 cabinet information on ETERNUS disk storage systems device using such functions as an OS management tool (format command etc ) or ETERNUS Web GUI, GDS provided by ETERNUS Storage Server, you need to reset the registered replication volume information associated with the changed volumes, by following these steps:
Delete the replication volume information using swsrpdelvol (Replication volume information deletion command)
In the GUI client, "information acquisition / Display" of all devices is performed, otherwise stgxfwcmsetdev (Device information collection / reflection command) is executed in a Storage Management Server.
Reset the replication volume information using swsrpsetvol (Replication volume information configuration 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 following cases:
When the group configuration conditions are not met
When both servers involved in inter-server replication are not running version 13.0 or later
When GDS SDX objects are used: Refer to "Configuration and conditions of unsupported SDX objects", and "11.1.5.2 Notes on SDX object operations (replication management)".
This command cannot be executed while any of the following commands are running:

>0:Terminated abnormally
EXAMPLES
Delete replication volume information on Storage Server SRC-SV.
# /opt/FJSVswsrp/bin/swsrpdelvol /dev/dsk/c1t2d0s3 /dev/dsk/c1t2d0s3@TARG-SV swsrpdelvol completed #
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 Storage Server that executed the command is not the operation server of the replication volume.
Communication with a Storage 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 or halt 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 with ETERNUS disk storage systems, or perform b).
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 GDS SDX objects are used: Refer to "Configuration and conditions of unsupported SDX objects", and "11.1.5.2 Notes on SDX object operations (replication management)".
This command cannot be executed while any of the following commands are running:

NOTES
Information is displayed only for cabinets that contain replication volumes for the server where the command was executed.
If inter-cabinet replication is being performed between servers, then the command must be executed on both servers involved in the replication in order to check information for the transfer buffers in both cabinets.
It will take a short time for changes to REC transfer buffer settings to take effect, during which time the buffer may become unusable (the "Rate" field will be displayed as "----"). In this case, wait about one minute and then execute the command again.
This command cannot be executed while the following command is running:

NOTES
The device name on a cabinet 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 asynchronous Consistency mode sessions in either the ACTIVE or ERROR SUSPEND state.
It will take a short time for changes to buffer settings to take effect, during which time the transfer buffer will become unusable. Do not perform REC operations during this time.
This command cannot be executed while any of the following commands are running:
