Administrator's Guide

NOTE:
• Physical disk resources usually do not have any dependencies set.
• In multi-node clusters it is necessary to specify the node to move the group to. When a cluster
group is moved to another node, all resources in that group are moved.
• When a physical disk resource is owned by a node, the disk appears as an unknown,
unreadable disk to all other cluster nodes. This is a normal condition. When the physical disk
resource moves to another node, the disk resource then becomes readable.
Creating file share resources
To create a file share resource, see two clustering online help topics:
• Create a cluster-managed file share
• Using a server cluster with large numbers of file shares
NOTE:
• A file share resource must reside in the same cluster group as the physical disk resource it will
reside on.
• The physical disk resource specified in this step must reside in the same cluster group as
specified in the beginning of this wizard.
Creating NFS share resources
To create an NFS share resource, see “MSNFS administration on a server cluster” (page 70).
Shadow copies in a cluster
It is recommended that the location of the cache file be placed on a separate disk from the original
data. In this case, a physical disk resource for the cache file disk should be created in the same
cluster group as the intended Shadow Copy resource and the volume for which snapshots will be
enabled. The resource should be created prior to the establishment of Shadow Copies. The Shadow
Copy resource should be dependent on both the original physical disk resource and the physical
disk resource that contains the cache file.
For more information, see the following topics in the clustering online help:
• Using Shadow Copies of Shared Folders in a server cluster
• Enable Shadow Copies for shared folders in a cluster
Extend a LUN in a cluster
To extend a LUN on a storage array in a cluster, review the requirements and procedures from
the storage array hardware provider for expanding or extending storage.
For additional information associated with extending a LUN in a cluster, see the following Microsoft
