Cluster Resource Group

When you create a new cluster, the cluster will contain (by default) a cluster group that contain the default settings and resources for the cluster. This group contains a list of the cluster resources, which includes the following:

•

Cluster IP address

IP network name (cluster network resource name)

Quorum disk

When you install the Cluster Service and configure the cluster in the Cluster Configuration wizard, the IP address and the name of the cluster you enter in the wizard becomes the IP address and IP network name of the cluster. If you prefer to relocate the quorum disk, you can move the quorum disk to another disk group.

Adding Additional Applications and Data to the Quorum Disk

The quorum disk, by default, is installed in the “Cluster Group.” Dell recommends that you do not install additional applications into the Cluster Group. The Cluster Group also contains a network name and IP address resource, which is used to man- age the cluster. However, if you choose to use the quorum disk for applications and data, Dell recommends that you perform the following steps:

1.Create a small partition on one of the shared RAID drives.

2.Allocate 100 megabytes (MB) to the partition.

One hundred megabytes (MB) (100 MB) is a satisfactory size for this partition, but no other applications or data should be stored there.

3.Assign a drive letter to the partition.

4.Assign the Cluster Service files (quorum disk) to this drive letter during installa- tion.

This procedure will prevent other application programs or data from filling the par- tition where the quorum resource is located.

NOTICE: If the quorum disk's partition becomes full, the quorum resource is not able to expand and may become corrupt. If a separate partition is not used for the quorum resource, ensure that the quorum disk’s partition does not become full when used by other applications or files.

You can place applications and data on the remaining partitions or space on the shared disk with the quorum resource partition. These partition(s) must be placed in the same cluster group as the quorum resource partition to ensure failover consistency.

5.Move the quorum disk (which the quorum resource partition) out of the cluster group and into another group.
