Configuring Shared Disks; Verifying Disk Access And Functionality; Configuring Cluster Service Software; Using Cluster Administrator - HP X1600 - StorageWorks Network Storage System 5.4TB SAS Model NAS Server User Manual

• Dedicate a separate disk resource for a Quorum disk. Because the failure of the Quorum disk
would cause the entire cluster to fail, HP strongly recommends that the disk resource be a RAID 1
configuration.
• Create a partition with a minimum of 50 megabytes (MB) to be used as a Quorum disk. HP recom-
mends a Quorum disk be 500 MB.
HP recommends assigning the drive letter Q for the Quorum disk. It is also helpful to label the volume
Quorum.
NOTE:
It is possible to change the Quorum disk by clicking the Quorum button. This displays a list of available
disks that can be used for the Quorum disk. Select the appropriate disk, and then click OK to continue.

Configuring shared disks

Use the Windows Disk Management utility to configure additional shared disk resources. Verify that
all shared disks are formatted as NTFS and are designated as Basic.
Additional shared disk resources are automatically added into the cluster as physical disk resources
during the installation of cluster services.

Verifying disk access and functionality

Write a file to each shared disk resource to verify functionality.
At this time, shut down the first node, power on the next node and repeat the Verifying Disk Access
and Functionality step above for all cluster nodes. When it has been verified that all nodes can read
and write from the disks, turn off the cluster nodes and power on the first, and then continue with this
guide.

Configuring cluster service software

Cluster Administrator (cluadmin) provides the ability to manage, monitor, create and modify clusters
and cluster resources.

Using Cluster Administrator

Cluster Administrator shows information about the groups and resources on all of your clusters and
specific information about the clusters themselves. A copy of Cluster Administrator is automatically
installed on a cluster node when the Cluster service is installed.

Creating a cluster

During the creation of the cluster, Cluster Administrator will analyze and verify the hardware and
software configuration and identify potential problems. A comprehensive and easy-to-read report is
created, listing any potential configuration issues before the cluster is created.
Some issues that can occur are:
• No shared disk for the Quorum disk. A shared disk must be created with a NTFS partition at least
50 MB in size.
