Configuring Shared Disks; Verifying Disk Access And Functionality - HP StorageWorks 4000s - NAS Administration Manual

Cluster Administration
During the Cluster service installation, a drive letter must be provided for the quorum disk. HP
recommends the drive letter Q for the quorum disk.

Configuring Shared Disks

Use the WebUI to configure additional shared disk resources. Verify that all shared disks are
formatted as NTFS and are designated as Basic.
Additional shared disk resources will be automatically added into the cluster as physical disk
resources during the installation of cluster services. Each physical disk resource will reside in
its own cluster group.

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.

Create a small partition [A minimum of 50 megabytes (MB) to be used as a quorum disk.
HP recommends a quorum disk to be 500 MB.]
Dedicate a separate disk resource for a quorum disk. As the failure of the quorum disk
would cause the entire cluster to fail, it is strongly recommended that the disk resource be
a RAID 1 configuration.
