HP StorageWorks Clustered File System 3.6.0 Windows Storage Server Edition Administration Guide (403103-005, January 2008)

Chapter 4: Cluster Administration 39
NOTE: Be careful not to accidently back up PSFS filesystems multiple
times by using both your site-defined drive letter/mount point
assignments and the reserved mount points created by HP
Clustered File System. Filter out the reserved mount points from
backup jobs, and instead use your own site-defined assignments.
(For more information about the reserved mount points, see
“Differences Between HP Clustered File System and Microsoft
Utilities for Volumes and Filesystems” on page 96.)
Back Up and Restore Membership Partitions
The membership partitions contain three databases that need to be
backed up:
• The device database, which contains information about imported
disks.
• The volume database, which contains information about dynamic
volumes.
• The mxds datastore, which contains cluster configuration information.
The device database and the volume database are automatically backed
up to the file conf\MP.backup whenever they are changed; your backups
of the conf directory will always contain up-to-date copies of these
databases.
The mxds datastore is automatically backed up to conf\MPmxds.backup
once-per-day. If you make configuration changes to the cluster, you may
want to make a backup copy of the mxds datastore to ensure that you
have an up-to-date backup.
Use the following command to back up the mxds datastore to the default
backup file, conf\MPmxds.backup:
mpdump -X
Use this command to back up the mxds datastore to the file of your
choice:
mpdump -x <output-file>
