Changing the HA configuration
To change the configuration of a NIC, select the server on the Servers panel, and then select NICs
from the lower Navigator. Click Modify on the NICs panel. The General tab on the Modify NIC
Properties dialog box allows you change the IP address and other NIC properties. The NIC HA
tab allows you to enable or disable HA monitoring and failover on the NIC and to change or
remove the standby NIC. You can also enable link state monitoring if it is supported on your cluster.
See “Configuring link state monitoring for iSCSI network interfaces” (page 34).
To view the power source for a server, select the server on the Servers panel, and then select Power
from the lower Navigator. The Power Source panel shows the power source configured on the
server when HA was configured. You can add or remove power sources on the server, and can
power the server on or off, or reset the server.
Configuring automated failover manually
To configure automated failover manually, complete these steps:
1. Configure file serving nodes in backup pairs.
2. Identify power sources for the servers in the backup pair.
3. Configure NIC monitoring.
4. Enable automated failover.
1. Configure server backup pairs
File serving nodes are configured in backup pairs, where each server in a pair is the backup for
the other. This step is typically done when the cluster is installed. The following restrictions apply:
• The same file system must be mounted on both servers in the pair and the servers must see the
same storage.
• In a SAN environment, a server and its backup must use the same storage infrastructure to
access a segment’s physical volumes (for example, a multiported RAID array).
For a cluster using the unified network configuration, assign backup nodes for the bond0:1
interface. For example, node1 is the backup for node2, and node2 is the backup for node1.
