In order to utilize PowerHA 7 SAN based communications in a VIO Server environment, what task
must be performed on the AIX client nodes?

An administrator is configuring a PowerHA 6 cluster to use disk heartbeat as a non IP network. A
shared volume group, dhbvg, has been configured using a single disk, hdisklO, on NodeA and
NodeB.
The administrator believes that the prerequisites have been met, but would like to test connectivity
of the disk heartbeat network before adding the network into the cluster.

How can the connectivity of this disk heartbeat network be tested?

There is a two-node cluster with Node1 and Node2. An administrator changes filesystem size on
Node1 by using the chfs command, and moves resource the group to Node2.
The administrator finds the change of filesystem size is recognized on Node2.
Why is the filesystem size change reflected on Node2?

A 2-node cluster has three multi-node disk heartbeat (MNDHB) networks and data volume groups
on separate disks. Application resource groups are online on Node1. What happens if Node1
loses access to two of the three MNDHB disks?

What is the command used to check the status of all interfaces and hearbeats in a PowerHA 7
cluster?
