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 matrix 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 matrix, 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>
If the -X option was used to back up the mxds datastore, use the
mpimport -X command to restore the datastore to the membership
partitions. If the -x <output-file> option was used for the backup, use
mpimport -x <output-file> to restore the datastore.
To restore the device database and volume database to the membership
partitions, use the mpimport -f <input-file> command. The input file is
typically conf\MP.backup.
For more information about mpdump and mpimport, see the PolyServe
Matrix Server Command Reference.
