Performing Backups and Restores in a MSCS Cluster
The process of configuring and performing backups and performing
restores in a cluster
is similar no matter which clustering solution you are using. Guidelines
and instructions
for backups and restores are covered in the chapter "Using NetBackup to
Perform
Backups and Restores in a Cluster" on page 83.
This following section covers information on restoring the cluster
quorum, which is
specific to a MSCS environment.
Restoring the Cluster Quorum for Windows 2000 Systems
The cluster quorum is backed up as part of System State for each node.
To restore the
cluster quorum, other nodes in the cluster must be offline. If you
cannot take the other
nodes in the cluster offline before restoring the cluster quorum, you
can create the
following registry entry to force the restore of the cluster quorum:
HKEY_LOCAL_MACHINE\Software\VERITAS\NetBackup\CurrentVersion\Config\
Cluster_Database_Force_Restore
Note The actual registry entry above must be on a single line.
If required, create this registry value as data type REG_SZ with a value
of YES. When this
value is set, the cluster service is stopped for any nodes that are
online.
Restoring the quorum to a node that is running Active Directory or to a
node that is
currently a domain controller, requires additional steps not listed
here. If Active Directory
is running on the target server or the target server is currently a
domain controller, see
"Restoring Cluster Quorum to Windows 2000 Node With Directory Services"
on page 12.
To restore the cluster quorum
1. From the NetBackup Backup, Archive, and Restore interface, select the
backup image
(or range of images) that contains the backup of the System State for
this node of the
cluster. Then, select the node of the tree labeled System_State as the
directory to be
restored. For details, see the section on performing restores in the
NetBackup User's
Guide for Windows.
2. If the disk where cluster quorum previously resided has been changed
(The disk
could have been replaced with a new one, or the disk configuration could
have been
changed so that the cluster quorum now resides on a different disk.),
you may have to
set the registry entry described above to force the restore to continue.
This allows the
drive letter of the disk that the cluster quorum was on to remain the
same, even if the
configuration has changed and the disk signatures contained in the
restore media do
not match the disk signatures contained in the cluster quorum.
3. Continue the restore operation as explained in the section on
performing restores in
the NetBackup User's Guide for Windows.
4. When the restore operation is complete, either reboot the cluster
node or use the
Microsoft Cluster Administrator to restart the cluster service on any
nodes where it
was stopped, whichever is appropriate.
Restoring Cluster Quorum to Windows 2000 Node With
Directory Services
To restore the quorum to a node that is running Active Directory or to a
node that is
currently a domain controller, the node must be in Directory Services
Restore Mode. The
cluster services cannot run in this mode, so the cluster quorum must be
restored
separately, after System State is restored and the node has been
rebooted.
To restore the cluster quorum to a node running Active Directory or that
is currently
a domain controller
1. From the NetBackup Backup, Archive, and Restore interface, select the
backup image
(or range of images) that contains the backup of the System State for
this node of the
cluster. Then, select the node of the tree labeled System_State as the
directory to be
restored. For details, see the section on performing restores in the
NetBackup User's
Guide for Windows.
2. Exclude the cluster quorum from being restored with System State at
this time by
expanding the System_State node and deselecting the Cluster_Database
node of the
tree.
3. Continue the restore operation by following the steps on performing
restores in the
NetBackup User's Guide for Windows.
4. When the restore operation is complete, reboot the cluster node in
safe (repair) mode
(restart the computer and press F8 when prompted to select an operating
system) and
then select Directory Services Restore Mode.
5. Start the NetBackup service(s).
6. In the NetBackup Backup, Archive, and Restore interface, expand the
System_State
node and select only the Cluster_Database node.
7. If the disk where the cluster quorum previously resided has been
changed, you may
have to set the registry entry described above to force the restore to
continue. The disk
could have been replaced with a new one, or the disk configuration could
have been
changed so that the cluster quorum now resides on a different disk. This
allows the
drive letter of the disk that the cluster quorum was on to remain the
same, even if the
configuration has changed and the disk signatures contained in the
restore media do
not match the disk signatures contained in the cluster quorum.
8. Continue the restore operation by following the steps in the section
on performing
restores in the NetBackup User's Guide for Windows.
9. When the restore has completed, reboot the target node.
10. When the restore operation is complete, use the Microsoft Cluster
Administrator to
restart the cluster service on any nodes on which it was stopped.
