Renaming The Local Area Network Icons; Verifying Connectivity And Name Resolution; Verifying Domain Membership; Setting Up A Cluster User Account - HP ProLiant 300 Series Administration Manual

access to cluster nodes could become unavailable if the DHCP server goes down. If DHCP must be used
for the public network adapter, use long lease periods to assure that the dynamically assigned lease
address remains valid even if the DHCP service is temporarily lost. Keep in mind that Cluster service
recognizes only one network interface per subnet.

Renaming the Local Area Network icons

HP recommends changing the names of the network connections for clarity. The naming helps identify
a network and correctly assign its role. For example, "Cluster interconnect" for the private network
and "Public connection" for the public network.

Verifying connectivity and name resolution

To verify name resolution, ping each node from a client using the node's machine name instead of its
IP number.

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 user 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 not belong to a user on the domain. This user account will need to
be granted administrator privileges.

About the Quorum disk

When configuring the Quorum disk only one node should be powered on. All other potential cluster
nodes must be powered off.
The quorum disk is used to store cluster configuration database checkpoints and log files that help
manage the cluster. The Quorum disk must be a shared disk resource. HP makes the following Quorum
disk recommendations:
NOTE:
Use the WebUI Disks tab to configure the Quorum disk resource.
• 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 small partition [A minimum of 50 megabytes (MB) to be used as a quorum disk. HP
recommends a Quorum disk be 500 MB.]
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. It is also helpful to label the volume Quorum.
