4.0.0 HP Polyserve Matrix Server Administration Guide (T5392-96052, March 2010)

• 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>
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 HP PolyServe Matrix
Server command reference guide.
Quotas information for PSFS filesystems
Windows utilities or third-party applications used to back up PSFS filesystems are
not aware of the Matrix Server quotas feature and cannot back up the quotas
information. Instead, when you back up a filesystem, also use the Matrix Server
psfsdq command to back up the quota information stored on the filesystem. After
restoring the filesystem, run the psfrq command to restore the quota information.
See “Back up and restore quotas” on page 139 for more information.
Matrix Server network port numbers
Matrix Server uses the following network ports for external and internal connections.
