Managing the Compaq ProLiant Clusters HA/F100 and HA/F200 5-5 Modifying Physical Cluster Resources Removing Shared Storage System Each cluster node, and the cluster as a whole, depends on the shared storage for data, log, and, possibly, application program files. If the shared storage is removed, all clustered applications that are dependent on that shared storage system will be offline. Clearly, network clients will not have access to the clustered applications. NOTE: These procedures for removing a shared storage system assume that you are making modifications to a previously configured HA/F100 or HA/F200. To remove a shared storage from your cluster, follow the steps below: 1. Use Cluster Administrator to bring offline all cluster groups and cluster resources including physical disk resources dependent on the RA4000 you are about to remove from the cluster. 2. Power off the RA4000 you are about to remove. Remove the Gigabit Interface Converter (GBIC) and the cable from the storage hub. 3. Delete the cluster groups and resources you brought offline in step 1. Adding Shared Storage System A Compaq StorageWorks RAID Array 4000 cannot be dynamically added to the cluster. Follow these steps to add another shared storage system to an existing cluster. NOTE: These procedures for adding a shared storage system assume that you are making modifications to a previously configured HA/F100 or HA/F200. The following method of adding shared storage assumes: s Service Pack 5 for Windows NT 4.0 is applied. s Compaq SmartStart CD 4.10 or later is used to apply system drivers. 1. Power down one of the cluster servers (Node2). 2. Insert the Compaq SmartStart and Support Software CD into the CD-ROM drive of the other cluster server (Node1). Power down Node1. 3. Insert all of the SCSI drives into the RA4000.

Managing the Compaq ProLiant Clusters HA/F100 and HA/F200

Modifying Physical Cluster Resources
Removing Shared Storage System
Each cluster node, and the cluster as a whole, depends on the shared storage
for data, log, and, possibly, application program files. If the shared storage is
removed, all clustered applications that are dependent on that shared storage
system will be offline. Clearly, network clients will not have access to the
clustered applications.
NOTE:
These procedures for removing a shared storage system assume that you are
making modifications to a previously configured HA/F100 or HA/F200.
To remove a shared storage from your cluster, follow the steps below:
1.
Use Cluster Administrator to bring offline all cluster groups and cluster
resources including physical disk resources dependent on the RA4000
you are about to remove from the cluster.
2.
Power off the RA4000 you are about to remove. Remove the Gigabit
Interface Converter (GBIC) and the cable from the storage hub.
3.
Delete the cluster groups and resources you brought offline in step 1.
Adding Shared Storage System
A Compaq StorageWorks RAID Array 4000 cannot be dynamically added to
the cluster. Follow these steps to add another shared storage system to an
existing cluster.
NOTE:
These procedures for adding a shared storage system assume that you are
making modifications to a previously configured HA/F100 or HA/F200.
The following method of adding shared storage assumes:
■
Service Pack 5 for Windows NT 4.0 is applied.
■
Compaq SmartStart CD 4.10 or later is used to apply system drivers.
1.
Power down one of the cluster servers (Node2).
2.
Insert the Compaq SmartStart and Support Software CD into the
CD-ROM drive of the other cluster server (Node1). Power down Node1.
3.
Insert all of the SCSI drives into the RA4000.
