After the utility program has been installed on both servers, all shared
ServeRAID groups and disk resources will be automatically created by the
IBM ServeRAID Cluster Solution setup program and then brought online.
Server A is the current owner of these groups.
11. Move the quorum resource from localquorum to a ServeRAID disk resource by
doing the following:
a. On Server A, run the Microsoft Cluster Administrator program and open a
connection to the cluster you just created.
b. Verify that the same server (for example, Server A) owns the ServeRAID
disk resources and the localquorum resource and that the quorum resource
is moved to a RAID level-1 logical drive.
Note: Set the quorum resources on a RAID level-1 logical drive. Do not
set the quorum resources on a RAID level-5 or level-5E logical
drive.
c. Right-click the cluster name to open the cluster.
d. Select Properties ; then, click the Quorum tab.
e. In the Quorum Resource field, select a ServeRAID shared disk.
f. Click OK .
g. Delete the Local Quorum Resource and the Local Quorum Group.
See the Microsoft Cluster Solution Administrator’s Guide for more information.
12. Install the latest Windows NT 4.0 Service Pack on both cluster server nodes.
Note: If you installed a Windows NT 4.0 Service Pack previously, you must
reinstall it now.
You now can move the shared disk resources manually using the Microsoft Cluster
Administrator program or automatically during failover.
See Microsoft Knowledge Base Article Q258750, “Recommended Private
’Heartbeat’ Configuration on a Cluster Server,” for additional configuration
information.
Creating additional ServeRAID disk resources on a Windows NT 4.0
ServeRAID cluster
You can use a ServeRAID logical disk that has not already been designated as a
cluster resource, or you can create a new array and logical disk on Server A, using
the ServeRAID Manager program. For more information about creating new arrays
and logical drives, see Chapter 4, “Configuring ServeRAID controllers” on page 35.
Note: Be sure to assign a unique shared merge-group number to the new shared
logical drive.
Important
Before creating the ServeRAID logical cluster resource, you must assign a permanent
(sticky) drive letter to the shared logical drive on both servers. The two servers must have
the same drive letters on each shared drive. If you do not assign permanent drive letters,
Windows NT might assign different drive letters on each server. Assigning a permanent
drive letter ensures that Windows NT assigns the same drive letter to the partition on both
servers.
