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.
AIX AdvancedCopy Manager implements the transaction volume unmount/mount operation using customized pre-processing and post-processing scripts. If a pre-processing script ends with an error during execution of backup/restoration, backup/restore processing is not performed.
For details about the pre-processing and post-processing, refer to "Appendix C Pre-processing and Post-processing of Replication".
When the operation corresponds to either of the following, it is necessary to customize the script used for replication pre-processing and post-processing when:
When replication target is a volume group.
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.
It is also necessary to deactivate a volume group (LVM) before it is used as a replication destination. It is then necessary to reconfigure the volume group after the copy is created.
Refer to "The reconfiguration of the volume group" in "6.8.2 Replication in Units of Physical Disks" for information on the reconfiguration of a volume group.
It is also necessary to configure a disk group before a VxVM volume is used as a replication destination. It is necessary to reconfigure the disk group after the copy is created.
Refer to "6.8.2 Replication in Units of Physical Disks" or "Reconfiguring Disk Group (for Server-to-server Replication)" of "6.9 VxVM Volume Operation" for information on the usage and the reconfiguration of a disk group.
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.
