This appendix describes shell scripts used for preprocessing and postprocessing of backup and restoration.
Note that a shell script described in this appendix has different linefeed positions due to formatting of this manual.
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.
Normally, the preprocessing acquires the mount status of a transaction volume using the transaction volume name and then performs the following processing:
|
Transaction volume status |
Preprocessing |
|---|---|
|
Mounted |
Unmount a transaction volume.(*1) |
|
Unmounted |
Take no action. |
*1 If the transaction volume cannot be unmounted, however, customize the shell script for pre-processing. For information on this customization, see the section on "When you do not want to unmount a transaction volume."
What to do in the postprocessing must be determined depending on what has been done in the preprocessing.
|
Preprocessing |
Postprocessing |
|---|---|
|
A transaction volume was unmounted. |
Remount the transaction volume. |
|
Take no action. |
Take no action. |
If no transaction volume has been mounted since the start of system operation (e.g., a transaction volume used as a database), neither pre- nor post-processing is performed.
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:
|
Error code |
Usage |
|---|---|
|
0-99 |
Unusable (reserved for AdvancedCopy Manager) |
|
100-255 |
Usable |
If post-processing was failed, execute the Resource match command because the consistency of resource information may be incomplete.
The name of the shell script for pre-processing before backup processing is as follows.
In the case of non-cluster operation
/etc/opt/FJSVswsts/sh/OpcBackup.pre
In the case of cluster operation
/etc/opt/FJSVswsts/<logic node name>/sh/OpcBackup.pre

Use an editor to delete the comments ("#") on the 90th to 100th, 104th, and 137th lines for a transaction volume that is mounted but you do not want to unmount, and indicate the target device in the if statement on the 90th line.
This operation is possible only when the file system is one of the following two:
ufs
SynfinityFILE (single-partition configuration)
The preprocessing by the customized scripts is as follows:
|
State of transaction volume |
preprocessing |
|---|---|
|
It is mounted. |
Updating to operating volume is deterred. |
The postprocessing by the customized scripts is as follows:
|
preprocessing |
Postprocessing |
|---|---|
|
Updating to operating volume was deterred. |
The updating deterrence to operating volume is canceled. Matching of the backup volume is checked. |
In the employment which used the standard script, since the beginning of the cash of a file system and renewal of subsequent are deterred by unmounting a file system before an advanced copy (EC/OPC), the adjustment of the data of the whole file system is guaranteed.
Although the flash of the cash of a file system and renewal of subsequent are deterred using lockfs-w when customizing a script and not unmounting a file system, a guarantee of the contents of a file is not offered about the file in Write Open (the database space of Oracle which is supporting on-line backup removes).
Moreover, when there is a process under renewal of metadata, the data adjustment of the file system itself is not secured on the specification of lockfs, either.
Therefore, it is necessary to take into consideration and cope with it by employment about the data adjustment when not unmounting a file system.
The name of the shell script for post-processing before backup processing is as follows.
In the case of non-cluster operation
/etc/opt/FJSVswsts/sh/OpcBackup.post
In the case of cluster operation

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.
Thus, in pre-processing, the mount state of the transaction volume is determined using its name, and the following processing is then performed:
|
Transaction volume status |
Preprocessing |
|---|---|
|
Mounted |
Unmount the transaction volume. |
|
Unmounted |
Take no action. |
What to do in the postprocessing must be determined depending on what has been done in the preprocessing.
|
Preprocessing |

|---|---|
|

Remount the transaction volume. |
|

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:

Restore processing is not possible on a mounted transaction volume that cannot be unmounted. Specify a device at the restore destination.
The name of the shell script for post-processing after restore processing is as follows.

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.
