Chapter 7: Maintenance
Most maintenance operations within a cluster may be performed with one or more
nodes online, and usually without taking the entire cluster offline. This
ability allows higher availability of cluster resources.

Installing Service Packs
Microsoft Windows NT service packs may normally be installed on one node at a
time and tested before you move resources to the node. With this advantage of
having a cluster, if something goes wrong during the update to one node, the
other node is still untouched and continuing to make resources available. As
there may be exceptions to the installation of a service pack and whether or
not it can be applied to a single node at a time, consult the release notes for
the service pack for special instructions when installing on a cluster.

Service Packs and Interoperability Issues
To avoid potential issues or compatibility problems with other applications,
check the Microsoft Knowledge Base for articles that may apply. For example,
the articles in table 5 discuss installation steps or interoperability issues
with Windows NT Option Pack, Microsoft SQL Server, and Windows NT Service Pack
4:

Replacing Adapters
Adapter replacement may usually be performed after moving resources and groups
to the other node. If replacing a network adapter, ensure the new adapter
configuration for TCP/IP exactly matches that of the old adapter. If replacing
a SCSI adapter and using Y cables with external termination, it may be possible
to disconnect the SCSI adapter without affecting the remaining cluster node.
Check with your hardware vendor for proper replacement techniques if you want
to attempt replacement without shutting down the entire cluster. This may be
possible in some configurations.

Shared Disk Subsystem Replacement
With most clusters, shared disk subsystem replacement may result in the need to
shut down the cluster. Check with your manufacturer and with Microsoft Product
Support Services for proper procedures. Some replacements may not require much
intervention, while others may require adjustments to configuration. Further
information on this topic is available in the Microsoft Cluster Server
Administrator's Guide and in the Microsoft Knowledge Base.

Emergency Repair Disk
The emergency repair disk (updated with Rdisk.exe) contains vital information
about a particular system that you can use to help recover a system that will
not start, allowing you to restore a backup, if necessary. It is recommended
that the disk be updated when the system configuration experiences changes. It
is important to note that the cluster configuration is not stored on the
emergency repair disk. The service and driver information for the Cluster
Service is stored in the system registry. However, cluster resource and group
configuration is stored in a separate registry hive and may be restored from a
recent system backup. NTBACKUP will backup this hive when backing up registry
files (if selected). Other backup software may or may not include the cluster
hive. The file associated with the cluster hive is CLUSDB and is stored with
the other cluster files (usually in c:\winnt\cluster). Be sure to check system
backups to ensure this hive is included.

System Backups and Recovery
The configuration for cluster resources and groups is stored in the cluster
registry hive. This registry hive may be backed up and restored with NTBackup.
Some third-party backup software may not include this registry hive when
backing up system registry files. It is important, if you rely on a third-party
backup solution, that you verify your ability to back up and restore this hive.
The registry file for the cluster hive may be found in the directory where the
cluster software was installed梟ot on the quorum disk.

As most backup software (at the time of this writing) is not cluster-aware, it
may be important to establish a network path to shared data for use in system
backups. For example, if you use a local path to the data (example: G:\), and
if the node loses ownership of the drive, the backup operation may fail because
it cannot reach the data using the local device path. However, if you create a
cluster-available share to the disk structure, and map a drive letter to it,
the connection may be re-established if ownership of the actual disk changes.
Although the ultimate solution would be a fully cluster-aware backup utility,
this technique may be a better alternative until such a utility is available.

What Not to Do on a Cluster Server
Below is a list of things not to do with a cluster. While there may be more
items that may cause problems, these items are definite words of warning.
Article numbers for related Microsoft Knowledge Base articles are noted where
applicable.

Do not create software fault tolerant sets with shared disks as members.
(Q171052)

Do not add resources to the cluster group. (Q168948)

Do not install MSCS when both nodes have been online and connected to the
shared storage at the same time without MSCS installed and running on at least
one node first.

Do not change computer names of either node.

Do not use WINS static entries for cluster nodes or cluster addresses. (Q217199)

Do not configure WINS or default gateway addresses for the private
interconnect. (Q193890)

Do not attempt to configure cluster resources to use unsupported network
protocols or related network services (such as IPX, Netbeui, DLC, Appletalk,
Services for Macintosh). Microsoft Cluster Server works only with the TCP/IP
protocol.

Do not delete the HKEY_LOCAL_MACHINE\System\Disk registry key while the cluster
is running, or if you are using local software fault tolerance.
