A.3 Pre-processing and Post-processing of Restoration

In AdvancedCopy Manager, restore processing must be performed while transaction volumes are unmounted.

Thus, in pre-processing, the mount state of the transaction volume is determined using its name and the following processing is then performed:

Table A.4 Pre-processing for a transaction volume
Transaction volume status	Preprocessing
Mounted	Unmount the transaction volume.
Unmounted	Take no action.

Post-processing tasks will be determined by what has occurred in pre-processing

Table A.5 Pre-processing and post-processing for restoration
Preprocessing	Post-processing
A transaction volume was unmounted.	Remount the transaction volume.
Take no action.	Take no action.

If special pre-processing or post-processing is required, you need to add the instructions as appropriate to the shell script.

When customizing a script, strictly observe the following rules regarding error codes:

Table A.6 Error code rules
Error code	Usage
0-99	Unusable (reserved for AdvancedCopy Manager)
100-255	Usable

Note

If the post-processing fails, the resource information may have inconsistencies. Execute swstsrsemtch described in Section, "swstsrsemtch (Resource match command)".
When restoring a file system in a volume group, refer to "Restore a volume group", and customize the pre-processing and post-processing scripts so that the unmount/mount command is carried out for all logical volumes across which a file system exists.
