Setting up networks
Verify that all network connections are correct, with private network adapters connected to other
private network adapters only, and public network adapters connected to the public network.
Configuring 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 Internet Protocol (TCP/IP) Properties.
•
In all cases, set static IP addresses for the private network connector.
Configuring 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 though 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.
Keep in mind that Cluster service recognizes only one network interface per subnet.
Renaming the local area connection 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 address.
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 512 MB to be used as a Quorum disk.
HP recommends assigning the drive letter Q for the Quorum disk. It is also helpful to label the
volume Quorum.
