IBM ServeRAID, User Reference

Problem Action
After one of the cluster servers has been shut
down normally and the surviving server takes
over the cluster resources, occasionally one
or more of the IBM ServeRAID logical drive
resources will stay in the online-pending state
for several minutes, after they are moved over
to the surviving server (when viewed with the
Cluster Administrator). After this, the resource
will go to the Failed state and the following
error message will be displayed in the
surviving server system log (as viewed with
the Event viewer).
For example, the Windows NT Event Log
Message:
Date: ??? Event ID: 1069
Time: ??? Source: ClusSvc
User: N/A Type: Error
Computer: ??? Category: (4)
Description:
Cluster resource ’IBM ServeRAID Logical
Disk name’ failed.
No action is necessary to bring the resource online after the failover.
MSCS will bring this resource online on the surviving server within
approximately 4 minutes.
If a previous version of IBM ServeRAID
Cluster Solution has been uninstalled, a
message is incorrectly displayed prompting
you to perform an upgrade when you attempt
to reinstall the ServeRAID Windows NT
Cluster Solution. You must delete the C3E76E53-F841-11D0-BFA1-08005AB8ED05
registry key. Complete the following steps to delete the registry key:
1. From the Start menu, click Run .
2. Type: REGEDIT and click OK . The Registry Editor window opens.
3. Select HKEY_CLASSES_ROOT\CLSID and delete
C3E76E53-F841-11D0-BFA1-08005AB8ED05 .
4. Reinstall the ServeRAID Windows NT Cluster Solution. For
instructions, see Chapter 13, “Configuring ServeRAID controllers
for clustering” on page 111.
Array identifiers and logical drive numbers
might change during a failover condition. By design, the array identifiers and logical drive numbers might
change during a failover condition. Consistency between the
merge-group numbers and Windows NT or Windows 2000
permanent (sticky) drive letters is maintained, while the ordering
process during a failover condition is controlled by the Microsoft
Cluster Server software and the available array identifiers on the
surviving server.
