This appendix describes shell scripts used for preprocessing and postprocessing of backup and restoration in AIX AdvancedCopy Manager.
Shell scripts used for preprocessing and postprocessing of backup or restoration are started before and after backup or restoration when a backup or restore execution command is executed.
These shell scripts describe processing required by AdvancedCopy Manager to back up or restore a transaction volume.
This chapter describes the setup of preprocessing and postprocessing.
Backup on AdvancedCopy Manager must be performed basically while access to a transaction volume from other processes is inhibited.
For this reason, the transaction volume is unmounted during pre-processing.
Post-processing is determined according to the operations performed during pre-processing.

If special preprocessing or postprocessing is required, you need to add the concerned processing to a shell script.
When customizing a script, strictly observe the following rules regarding error code:

For backing up the volume group that includes logical volume in which the file system has been built, see "Backup a volume group" and the script of preprocessing and postprocessing has to be customized to execute unmount/mount processing for all logical volume in which the file system has been built.
If post-processing was failed, execute the Resource match command (swstsrsemtch) because the consistency of resource information may be incomplete.
The name of the shell script for pre-processing before backup processing is as follows.

When the volume group containing the logic volume by which the file system was built is a candidate for backup, it is necessary to correct an order processing script.
Please comment ("#")-turn the exit sentence of the 75th line of a pretreatment script (OpcBackup.pre) after correcting a script.
Please correct the comment of the 79-148th line of a pretreatment script (OpcBackup.pre), and the comment of the 78-153rd line of a post-processing script (OpcBackup.post) by the editor etc., and correct the description in a comment suitably so that unmount/mount processing is carried out to all the logic volumes by which the file system was built. (Please change the part shown by "*" according to an actual environment. Moreover, please describe it according to the number to be processed the processing of the 115-147th line of the preprocessing script (OpcBackup.pre) and the processing of the 116-147th line of the postprocessing script (OpcBackup.post) when processing it to two or more logical volumes.
Note that unmount/mount processing to a volume group is not carried out in the state where not customized.
If the backup volume is a volume group, deactivate the backup volume during backup pre-processing.
Please correct suitably parameters, options, etc. of the OS command, such as the mount command and the fsck command, according to employment.
Customize of a preprocessing and postprocessing script is needed, when performing cluster oprating by VERITAS Cluster Server, and when mount point of transaction volume is registered into cluster transaction.
Please change unmount/mount processing in preprocessing and postprocessing script into offline/online processing of mount point resource.
Moreover, the Volume is actually after doing offline/online of mount point resource and there will be a time difference by the time mount/unmount is done.
Therefore, please add the processing (The Result of sleep and the df Command is observed) meets until mount/unmount is actually done after the location where the success or failure of offline/online is judged.
The examples below show how the preprocessing and postprocessing scripts are modified.

In AdvancedCopy Manager, restore processing must be performed while transaction volumes are unmounted.
Therefore, transaction volume is unmounted in pre-processing.
What to do in the postprocessing must be determined depending on what has been done in the preprocessing.

When restoring a volume group that includes the logical volumes in which a file system is constructed, see "Restore a volume group", and customize the script of preprocessing and postprocessing so that the unmount/mount processing is carried out for all logical volumes in which a file system is constructed.
If pos-tprocessing was failed, execute the Resource match command (swstsrsemtch) because the consistency of resource information may be incomplete.
The name of the shell script for pre-processing before restore processing is as follows.

Restore processing is not possible on a mounted transaction volume that cannot be unmounted. Specify a device at the restore destination.

When the volume group containing the logic volume by which the file system was built is a candidate for restoration, it is necessary to correct an order processing script.
Please comment ("#")-turn the exit sentence of the 71th line of a pretreatment script (OpcRestore.pre) after correcting a script.
Please correct the comment of the 75-141th line of a pretreatment script (OpcRestore.pre), and the comment of the 95-170th line of a post-processing script (OpcRestore.post) by the editor etc., and correct the description in a comment suitably so that unmount/mount processing is carried out to all the logic volumes by which the file system was built. (Please change the part shown by "*" according to an actual environment. Moreover, please describe it according to the number to be processed the processing of the 111-140th line of the preprocessing script (OpcRestore.pre) and the processing of the 133-164th line of the postprocessing script (OpcRestore.post) when processing it to two or more logical volumes.
When the backup volume is mounted, the LVM management information in the backup volume is rewritten and the normal procedure cannot be used to restore the volume. In such cases, convert lines 65 to 79 and 95 to 170 in the post-processing script (OpcRestore.post) into comments ("#"). Furthermore, an additional step is required after restoration is completed. See "Notes on restoration."
Note that unmount/mount processing to a volume group is not carried out in the state where not customized.
Please correct suitably parameters, options, etc. of the OS command, such as the mount command and the fsck command, according to employment.
Customize of a preprocessing and postprocessing script is needed, when performing cluster oprating by VERITAS Cluster Server, and when mount point of transaction volume is registered into cluster transaction.
Please change unmount/mount processing in preprocessing and postprocessing script into offline/online processing of mount point resource.
Moreover, the Volume is actually after doing offline/online of mount point resource and there will be a time difference by the time mount/unmount is done.
Therefore, please add the processing (The Result of sleep and the df Command is observed) meets until mount/unmount is actually done after the location where the success or failure of offline/online is judged.
The examples below show how the preprocessing and postprocessing scripts are modified.
