Backup of LPAR manager
This section describes backing up the LPAR manager configuration.
Backup Files for LPAR manager

When in failure, backup files of LPAR manager configuration information allow you
to rapidly recover the system. It is recommended that you back up LPAR manager
configuration information on a regular basis in case you need to restore the LPAR
manager configuration in normal operation.

Hardware failure may cause a device to be degenerated or isolated. LPAR manager
cannot recognize degenerated or isolated devices, and a part of LPAR manager
configuration information related to the devices will be deleted or reconfigured. If this
happens, restore the backup files after hardware is replaced by service personnel.
