5 If you are using multipath I/O, in the Cluster Administrator, right-click the
network name that represents your SAN network and select Properties.If
you are not using multipath I/O, you have completed the network
configuration modifications.
In the Network Properties window, uncheck Enable this network for
cluster use option. This allows multipath I/O to control the link failover for
the SAN interfaces.
NOTE:
If all the redundant network connections fail on the node that is controlling
the cluster, services fail over to another node. This is because the cluster cannot
reach the backend of the PS Series storage.
It is recommended that you test multipath I/O failover. On a cluster node,
unplug one of the network cables that connects to the SAN network. The
connectivity to the PS Series storage array should not be lost.
