In AdvancedCopy Manager, replication processing must be performed while volumes are unmounted. Therefore, when replication is executed, processing to mount and unmount the volume is performed by the pre-processing and post-processing scripts respectively.
The replication processing is not executed when the volume cannot be unmounted.
For details of the pre-processing and post-processing, refer to "Appendix C Pre-processing and Post-processing of Replication".
Replication pre-processing and post-processing need to be customized when operational requirements change.
For example:
For specific operational requirements, you want to avoid the unmount/mount processing of the volume where a file system is constructed.
If you want to add special pre-processing or post-processing.
Refer to "Appendix C Pre-processing and Post-processing of Replication" for information on the customization.
Note
The pre-processing and post-processing are not performed in case of replicating a group.
Unmount all the volumes in the group before replication, and mount all the volumes after replication.
Pre-processing and post-processing are not executed for the slices included in a Logical Unit (disk) when Logical Unit (disk) unit copying is executed. Therefore, the slices included in a Logical Unit (disk) must be unmounted before a replica is created, and the unmounted slices must be mounted after the replica is created.
Point
The script may need to be updated after an upgrade of AdvancedCopy Manager.
Therefore, you should check the script after any upgrade to ensure it is compatible with newer versions.
