Cluster Administration Configure the Private Network Adapter The following procedures are Best Practices provided by Microsoft and should be configured on the private network adapter. ■ On the General tab of the private network adapter, ensure that only TCP/IP is selected ■ Ensure that the Register this connection's address in DNS is not selected in the DNS tab under advanced settings for the private network adapter ■ Ensure that the Link Speed and Duplex is set to 100Mps/Full Duplex under the advanced tab for the Ethernet card used for the private network adapter Configure the Public Network Adapter While the public network adapter's IP address can be automatically obtained if a DHCP server is available, this is not recommended for cluster nodes. HP strongly recommends setting static IP addresses for all network adapters in the cluster, both private and public. If IP addresses are obtained via DHCP, 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. In all cases, set static IP addresses for the private network connector. Keep in mind that Cluster service will recognize only one network interface per subnet. Rename the Local Area Network Icons HP recommends changing the names of the network connections for clarity. The naming will help to identify a network and correctly assign its role. 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.
