Verifying domain membership All nodes in the cluster must be members of the same domain and able to access a domain controller and a DNS Server. Setting up a cluster account The Cluster service requires a domain user account under which the Cluster service can run. This user account must be created before installing Cluster service, because setup requires a user name and password. This user account should be a unique domain account created specifically to administer this cluster. This user account will need to be granted administrator privileges. About the Quorum disk HP makes the following Quorum disk recommendations: • 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 recommends 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. 136 Cluster administration

and a DNS Server.

HP makes the following Quorum disk recommendations:
•
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
recommends 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
