DESCRIPTION

Start the synchronous replication processing (copying between disks by EC and REC).
It will copy all the data from the source volume to the destination volume at the start of the synchronization process, or if run as a restart of the synchronization process it will just copy updated data to the destination volume. Use this command at the start of operation or when you want to reflect updated data (differences) from the equivalency maintenance state.


OPTIONS

-h Server-Name

This option is valid only on a Management Server.
This option can be specified only on a Management Server.

-y

Specifies inter-box synchronization in synchronous mode. This option is valid only when total copy is started for inter-box replication.
Specify this option together with the -a option to start the split mode for inter-box synchronization in Automatic Split mode.
Specify this option together with the -v option to start the mode in Manual Split mode.
Specifying the -y option without the -a or -v option starts the mode in Automatic Split mode.
Not specifying the -y, -k, and -i options sets Through mode.
Synchronization in intra-box replication is always handled in synchronous mode.

-a

Specifies the start of split mode for inter-box synchronization in Automatic Split mode. This option is valid only when total copy is started for inter-box replication.
Specify this option together with the -y option.

-v

Specifies the start of split mode for inter-box synchronization in Manual Split mode. This option is valid only when total copy is started for inter-box replication.
Specify this option together with the -y option.
You must specify this option when specifying synchronization mode (the -y option) on a box that does not support Automatic Split mode.

-k

Specifies the setting of transfer mode for inter-box synchronization in Stack mode. This option is valid only when total copy is started for inter-box replication.
Not specifying the -y, -k, or -i option sets Through mode.

-i

Specifies the setting of transfer mode for inter-box synchronization in Consistency mode. This option is valid only when total copy is started for inter-box replication.
Not specifying the -y, -k, or -i option sets Through mode.

-g

Specifies the setting of recovery mode for inter-box synchronization in Manual Recovery mode. This option is valid only when total copy is started for inter-box replication.
Not specifying this option sets Automatic Recovery mode.

-m

For server-to-server replication, this option specifies that communication processing with non-operational servers is not performed. When this option is specified, volume status check processing and the pre-processing for the replication destination volume of a non-operational server are not performed.
This option is valid only during server-to-server replication.

-t

Specifies that pre-processing for the replication destination volume is not performed.
Use this option if any of the following conditions apply:

  • AdvancedCopy Manager does not perform pre-processing or post-processing for the replication destination volume, and independent pre-processes and post-processes are inserted before and after AdvancedCopy Manager commands.(*)

  • Replication destination pre-processing and post-processing are judged to be unnecessary (for example, for databases constructed on RAW devices).(*)

  • Synchronous processing (REC) between boxes is restarted after a forcible suspend.

*: If you specify this option to start or resume synchronous processing, specify the -t option also when executing swsrpmake (Replication creation command).

-Xgroup Group-Name

Specifies that synchronous processing must be started for each group.

-Xreverse

Specifies that synchronous processing must be started for each group in the reverse direction (from replica volumes to original volumes).

-Xskip

Specifies that synchronous processing must be suspended using the initial copy skip function. This option is valid only when total copy is started for inter-box replication.

-Xremain

Enables data that has been updated to the copy destination during replication established status when synchronous processing is restarted.
This option is valid only when inter-box replication is restarted.
This option is used to reflect to the copy destination volume only those parts of the copy source volume that have been updated, after synchronous processing has been started using the -Xskip option and backup data has been copied from the tape medium to the copy destination volume.

-Xda

Disables update (WRITE) and access (READ) to the replication destination volume from the synchronous processing start until the replication has been completed.
This option is valid only when synchronous processing is started.
If the option is omitted, only update (WRITE) to the replication destination volume is disabled.

DESCRIPTION

When synchronization processing (EC) is not performed, this command will start snapshot processing (OPC/QuickOPC/SnapOPC/SnapOPC+) to create a replication volume.

When synchronization processing is performed, check whether the status of the processing is in the equivalency maintenance state. If so, suspend the synchronization processing and create a replication volume. The status in which synchronization processing is suspended is referred to as the replication established status. After this command is executed, the replication destination volume can be accessed.

This command executes the replication pre-processing and post-processing before a replication is created. For details of these processes, refer to "Appendix C Pre-processing and Post-processing of Replication".


OPTIONS

-h Server-Name

Specifies a Managed Server name.
This option can be specified only on a Management Server.

-m

For server-to-server replication, this specifies that communication processing is not performed with the non-operation server. When this option is specified, volume status check processing and pre-processing and post-processing are not performed for the non-operation server volume.
This option is valid only during server-to-server replication.

-f

Specifies that the pre-processing and post-processing are not performed for a replication source volume.
Use this option only when AdvancedCopy Manager does not execute pre-processing and post-processing of the copy source volume and unique pre-processing and post-processing scripts are inserted before and after (respectively) the AdvancedCopy Manager command, or when you judge that copy pre-processing and post-processing are unnecessary (e.g., for a database constructed on a raw device).

-t

Specifies that the pre-processing and post-processing are not performed for a replication destination volume.
Use this option when applied to either of the following conditions:

  • Pre-processing and post-processing for copy destination volume is not performed by AdvancedCopy Manager but independent pre-processing and post-processing is added in before and after AdvancedCopy Manager commands.

  • Pre-processing and post-processing for copy destination volume is determined to be unnecessary (e.g. Database created on RAW device)

If you specify the -t option to execute swsrpstartsync (Synchronous processing start command), specify the -t option also when executing this command.

-Xflush

Specifies the flushing of the file system buffer of the copy source volume. Before this option is specified, all write processing on the copy source volume must be stopped. If a replica is created without the write processing stopped, then the integrity of the copy source volume data is not guaranteed.
When this option is omitted, the flushing of file system buffer of the copy source volume and locking of the copy source volume are based on the value of 'BufferFlushOnly' in the copy source volume locking specification file. For details, refer to "C.2.4 Copy source volume locking specification file".

-j

Specifies that copy processing will be forcibly suspended even if the execution status of copying is "sync: Total copy or incremental copy is being performed" or "halt: Hard suspend status" in synchronization processing of intra-box replication. This option can only be used for intra-box replication; if attempted for intra-box replication, an error will occur.
When this option is specified, the data in the destination volume is not guaranteed.
Additionally, when this option is specified, pre-processing and post-processing for the source and destination volumes are not performed. When restarting synchronous processing (REC) between boxes, execute swsrpstartsync (Synchronous processing start command) with the -t option specified.

-T

Specifies that differential snapshot processing will be executed.
This option cannot be specified while synchronous processing is performed.
This option is valid only for a replication within the ETERNUS Disk storage system and when the ETERNUS Disk storage system supports the QuickOPC function.
For a snapshot replication without specifying this option, ordinary snapshot processing (OPC without using the QuickOPC function) is started. This option must be specified to perform the replication operation using differential snapshots.

-Xgroup Group-Name

Specifies that a replication will be created for each group.

-Xreverse

Specifies that a replication will be created for each group in the reverse direction (i.e., from replica volumes to original volumes).

-Xconcur

Specifies that a replication will be created using the concurrent suspend function.

This option is not supported when GDS Snapshot linkage is being used.

Xconcur-opc

Specifies that a replication will be created using the concurrent OPC function.

This option is not supported when linking with GDS Snapshot.

-C

Specifies that SnapOPC will be started.
This option is only valid for intra-box replications and for ETERNUS Disk storage system that supports the SnapOPC function.
In order to execute SnapOPC, the copy destination volume must be a Snap Data Volume.

-P

Specifies to start SnapOPC+.
This option is only valid with intra-box replications and for ETERNUS Disk storage system that supports the SnapOPC+ function.
In order to execute SnapOPC+, the copy destination volume must be a Snap Data Volume.
An error occurs in the following cases:

  • The same SnapOPC+ session exists at the copy source volume and the copy destination volume.


OPERANDS

From-Volume-Name

Specifies a replication source volume.
Specifies the replication source volume or the replication destination volume that was set with swsrpsetvol (Replication volume information setting command).
Specifies the AdvancedCopy Manager device name for the volume name.

To-Volume-Name

Specifies a replication destination volume.
Specifies the replication source volume or the replication destination volume that was set with swsrpsetvol (Replication volume information setting command).
Specifies the AdvancedCopy Manager device name for the volume name.

For the items displayed by this option, refer to the table in the description above.

-E

An option which when set will display the operational status in the opposite direction only (from the copy destination to the copy source).
If this option is not set, the operation status will always be displayed in the normal direction (from the copy source to the copy destination) when a bi-directional OPC physical copy is taking place.
In case this option is set, the operational status in the normal direction will not be displayed. Only the operational status in the opposite direction will be displayed.
This option can be used to check the operational status of an OPC session performed in the opposite direction if a QuickOPC/SnapOPC session in the normal direction exists.

Specifies that the operation statuses are displayed by the group.
If this option is set, all the operational statuses relating to the specified group will be displayed.

-H

Changes the Status column display method used when a REC enters a hard-suspend (halt) status.
If this option is specified, then "halt (sync)" will be displayed when hard-suspend status occurs during a total copy or a differential copy. "halt (equivalent)" will be displayed when hard-suspend status occurs during an equivalency maintenance state.
If the transfer mode is Consistency mode and a REC Disk buffer is set, "halt(use-disk-buffer)" will be displayed when issue of a hard suspend causes transfer data to be saved to the REC Disk buffer.
If the transfer mode is Consistency mode and a REC buffer is set, "halt(use-buffer)" will be displayed when issue of a hard suspend causes transfer data to be saved to the REC buffer.

-O

Changes the error suspend(failed) status Status column display method.
If this option is specified, the display will be as follows:
There is a bad sector: "failed(badsector)"
When there is insufficient Snap Data Volume or Snap Data Pool capacity: "failed(overflow)"
All other cases: "failed(other)"

To be executed on the Management Server: group specification
<program-directory>\bin\swsrpcancel -h Server-Name [-c] {([-f] [-t] [-m] [-b])|[-T]} [-Xreverse] [-Xflush] [-Xforce] -Xgroup Group-Name

DESCRIPTION

This command stops snapshot processing (OPC/QuickOPC/SnapOPC/SnapOPC+) and synchronization processing (EC) of the specified replication volume. Use this command when an error is detected during the replication operation and when you want to stop replication processing.


OPTIONS

-h Server-Name

Specifies a Managed Server name.
This option can be specified only on a Management Server.

-c

Specifies that the copy processing is forcibly stopped from a non-operation server when the operation server cannot be used because of a system failure. If this option is used, the copy processing is stopped without implementing pre-processing and post-processing.

As a result, the copy destination volume may become locked if copy processing is cancelled using this option. Check the status of the copy destination volume using swstvollockstat (Locked-volume information display command) and, if it is locked, unlock the volume using swstvolunlock (Volume unlock command).

This option cannot be specified on the operation server.

-m

For server-to-server replication, this option specifies that communication processing is not performed with non-operation servers. When this option is specified, volume status check processing and pre-processing and post-processing are not performed for the replication destination volume of a non-operation server.
This option is valid only during server-to-server replication.

-f

When stopping synchronous processing under the equivalency maintained status, specify that pre-processing and post-processing for the copy source volume is not being executed.
Use this option only when AdvancedCopy Manager does not execute pre-processing and post-processing of the copy source volume and unique pre-processing and post-processing scripts are inserted before and after (respectively) the AdvancedCopy Manager command, or when you judge that copy pre-processing and post-processing are unnecessary (e.g., for a database constructed on a raw device).

-t

When stopping the synchronous processing under the equivalency maintained status, this specifies that post-processing for the copy destination volume will not be executed.
Use this option only when AdvancedCopy Manager does not execute pre-processing and post-processing of the copy destination volume and unique pre-processing and post-processing scripts are inserted before and after (respectively) the AdvancedCopy Manager command, or when you judge that copy pre-processing and post-processing are unnecessary (e.g., for a database constructed on a raw device).

-Xflush

Specifies flushing the file system buffer of the copy source volume when synchronous processing under the equivalency maintained status is stopped. Before this option is specified, all write processing on the copy source volume must be stopped. If a replica is created without the write processing stopped, then the accuracy of the copy source volume data is not guaranteed.
The file system buffer can be flushed by specifying 'on' for BufferFlushOnly in the copy source volume locking specification file instead of using this option.

When this option is omitted, the flushing of file system buffer of the copy source volume and locking of the copy source volume are based on the value of 'BufferFlushOnly' in the copy source volume locking specification file.

For details, refer to "C.2.4 Copy source volume locking specification file".

-b

Specifies that the inter-box copy operation in the halt status be stopped.
For replication on a single server, the copying is cancelled for both boxes.
For replication between servers, the copying is cancelled only for the box connected to the server on which this command was executed.
Use the option only for a copy operation in the halt status and whose recovery is not expected to be done successfully.
The option is valid only for a copy operation in the HALT status.
The option can be used on the server that is not specified as the operation server.

If this option is specified together with the -Xgroup option, copy processing is only stopped for sessions in the group whose status is halt.

-T

Specifies that differential snapshot processing will be terminated.
This option only terminates tracking processing and does not terminate snapshot processing (OPC physical copying) when it is in progress. This option releases the OPC session if snapshot processing (i.e., OPC physical copying) is complete.
This option can only be used while physical copying or tracking is in progress.

If this option is specified together with the -Xgroup option, only tracking processing within the group is stopped.

-Xgroup Group-Name

Specifies that copy processing will be stopped for each group.

-Xreverse

Specifies that copy processing that is being executed in the reverse direction (from replica volumes to original volumes) will be stopped.

-Xforce

Specification of this option forcibly stops a SnapOPC+ session.
Forcibly stopping SnapOPC+ stops the specified snap generation and all earlier snap generations.
This option can be specified even if there is only one snap generation.
This option is a SnapOPC+ fixed option.
If this option is specified at the same time as the -Xgroup option, the SnapOPC+ sessions in that group are stopped, and all the snap generations and snap generations before it in the group are also stopped.


OPERANDS

You can specify either of the following parameters in the operand:

Auto : Changes to Automatic Split mode.
Manual : Changes to Manual Split mode.

Changing the split mode requires this option.
To specify this option, you must also specify -F Sync, or the transfer mode of the current synchronization must be synchronous mode.

-Xgroup Group-Name

Changes the operation mode of inter-box synchronous processing for each group (transfer mode, recovery mode, or split mode).

-Xreverse

Specifies that the operation mode of synchronous processing that is being executed in reverse direction (from replica volumes to original volumes) will be changed.


OPERANDS

From-Volume-Name

Specifies a copy source volume name.
Specifies the replication source volume or the replication destination volume set with swsrpsetvol (Replication volume information setting command).
Specifies the AdvancedCopy Manager device name for the volume name.

To-Volume-Name

Specifies a copy destination volume name.
Specifies the replication source volume or the replication destination volume set with swsrpsetvol (Replication volume information setting command).
Specifies the AdvancedCopy Manager device name for the volume name.


EXIT STATUS

=0: Completed successfully
>0: Terminated abnormally

NOTES

12.4.2.6 swsrprevsync (Synchronization reverse command)

NAME

swsrprevsync - reverses the copying direction of synchronization


SYNOPSIS

To be executed on the Managed Server
<program-directory>\bin\swsrprevsync From-Volume-Name To-Volume-Name
To be executed on the Management Server
<program-directory>\bin\swsrprevsync -h Server-Name From-Volume-Name To-Volume-Name
To be executed on the Managed Server: group specification
<program-directory>\bin\swsrprevsync [-Xreverse] -Xgroup Group-Name
To be executed on the Management Server: group specification
<program-directory>\bin\swsrprevsync -h Server-Name [-Xreverse] -Xgroup Group-Name

DESCRIPTION

This command reverses the copying direction of synchronization when in suspended status.

Note that this command cannot be used to handle a logical volume of an SDX object.


OPTIONS

-h Server-Name

Specifies the name of a Managed Server.
This option can be specified only on a Management Server.

-Xgroup Group-Name

Changes the direction of synchronous processing for each group.

-Xreverse

Specifies that the direction of synchronous processing that is being executed in reverse direction (i.e., from replica volumes to original volumes)will be inverted.


OPERANDS

From-Volume-Name

Specifies a copy source volume name. (as the destination in the reverse direction)
Specifies the replication source volume or the replication destination volume set with swsrpsetvol (Replication volume information setting command).
Specifies the AdvancedCopy Manager device name for the volume name.

To-Volume-Name

Specifies a copy destination volume name. (as the source in the reverse direction)
Specifies the replication source volume or the replication destination volume set with swsrpsetvol (Replication volume information setting command).
Specifies the AdvancedCopy Manager device name for the volume name.


EXIT STATUS

=0: Completed successfully
>0: Terminated abnormally
