This section provides information on the maintenance of a backup management list. A backup management list is maintained on the server that performs the backup.
A backup management list is backed up.
For details of this, refer to swstresback (Resource backup command).
Backup management list backup data size
Check the size of the file that the subdirectory of the following directory contains.
/etc/opt/FJSVswsts/data |
In the cluster environment, check the size of the file that the subdirectory of the following directory contains
/etc/opt/FJSVswsts/<logic node name>/data |
Point
When you reuse a directory used before to save the data, the size of this directory must be capable of supporting repositories which have been allocated a size to cater for high growth. Rule of thumb would suggest that the file system in which these directories exist should be at least three times greater than the size returned in query above.
A backup management list is restored.
For details of this, refer to swstresrst (Resource restore command).
AIX AdvancedCopy Manager uses transaction volumes and backup volumes as volume groups. If LVM volume management information is lost, volumes cannot be backed up or restored correctly. When a volume group is created, it is recommended volume configuration information be backed up using the savevg command in preparation for a system crash. For information on the savevg command, refer to the AIX manuals.
This section describes the maintenance of a replication management list.
To back up a replication management list, back up the repository of the Storage Management Server. For information about backing up a repository, refer to "Saving a database" relevant to the OS of the Storage Management Server.
Point
Operational information for replication management is saved in a repository.
It is recommended that a replication management list be backed up when operation information for replication management is changed with swsrpsetvol (Replication volume information configuration command), or with swsrpdelvol (Replication volume information deletion command).
Perform the following steps to restore a replication management list:
Restore the repository to the Storage Management Server. For information about restoring a repository, refer to "Recovering a database" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" relevant to the OS of the Storage Management Server.
If the Storage Management Server is Windows
Select "RDB dictionary and DSI recovery (LOAD Mode)" as the recovery method.
If the Storage Management Server is Solaris or Linux
Specify 0 for stgdbrcv -m option (recovery mode) as the recovery method.
On the Storage Server, execute swsrprecoverres (Resource adjustment command) with the -r option specified. For details of the resource adjustment command, refer to "swsrprecoverres (Resource adjustment command)".
Point
When step 1 above is performed, operational information for replication management of a repository is copied to a Storage Server, where it is then available for use.
When this information for replication management in the repository does not need to be changed, and only the operation information for replication management on the Storage Server is incorrect (for some reason), perform only step 2.
AIX AdvancedCopy Manager uses source and replica volumes as volume groups. If LVM volume management information is lost, correct operations cannot be achieved. When a volume group is created, it is recommended volume configuration information be backed up using the savevg command in preparation for a system crash. For information on the savevg command, refer to the AIX manuals.
For information about maintaining a database used by a Storage Management Server, refer to the "Maintaining a database" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" relevant to the OS of the Storage Management Server:
For information about maintaining an authentication management, refer to the "Maintaining an authentication management list" in the "ETERNUS SF AdvancedCopy Manager Operator's Guide" relevant to the OS of the Storage Management Server:
This section describes the maintenance of a registry. Perform this procedure on a Storage Management Server or a Storage Server.
In a command prompt window, back up the following files using the copy command, etc.
/etc/opt/swstorage/swnode.ini
/etc/opt/swstorage/Logical-node-name/swnode.ini
Save it in the /backup directory.
# cp /etc/opt/swstorage/swnode.ini /backup |
Registry backup data size
Check the size of the file to be backed up.
In a command prompt window, use the copy command or another method to restore the following files.
/etc/opt/swstorage/swnode.ini
/etc/opt/swstorage/Logical-node-name/swnode.ini
Restore the following file saved in the /backup directory:
# cp /backup/swnode.ini /etc/opt/swstorage |
