If a failure occurs in the management partition, the GFS Shared File System within a cluster system stops. To overcome this, it is recommended to mirror the volumes within the management partition.
Also, prior to changing the configuration of the file system, make a backup of the management partition information with sfcgetconf(8).

For details on backup of the management partition, see "9.6 Backup of the management partition information" and "9.7 Restoring of the management partition information".
