Adding Shared Storage

A ProLiant storage system cannot be added while the cluster is running.
Follow these steps to add another shared storage system to an existing cluster.
1. Use Microsoft Cluster Administrator to bring all cluster groups and
resources offline.
2. When installing the new storage system, you do not want the cluster
service to start automatically. On each server node, go into the
Windows NT Services Control Panel applet and set the cluster service to
Manual.
3. Shut down and power off both server nodes and the shared storage
array.
4. Plug all of the SCSI drives into the shared storage array.
5. Power up the newly added storage system and the CL1850 shared
storage array.
6. Power up server node 1 and run the CR3500 Configuration Utility. Set
up the logical drives.
IMPORTANT: Be sure you understand your cluster groupings of applications and
resources whose data, log, and program files may reside on these drives. See Chapter 4
for information on creating cluster group.
7. Run Disk Administrator to assign permanent letters to the drive
volumes.
8. Shut down the server node 1.
9. Power up the server node 2.
IMPORTANT: Do not run the CR3500 Configuration Utility on the second server node. The
information entered from the first server node is maintained on the drives; therefore, the
drives are already configured for the second server node.
10. Boot Windows NT on server node 2, then run Disk Administrator.
Verify that the drive letters displayed are the same as those assigned
from the first server node.
11. Power on server node 1 and allow it to boot into Windows NT. Go into
the Service Control Panel applet and start the cluster service. Start
Cluster Administrator and verify that the added drives are visible as
unassigned physical disk resources.
