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?

A.
On NodeA run the command /usr/bin/readvgda-V dhbvg -F status
On NodeB run the command /usr/bin/putvgda-V dhbvg -a status=1

B.
On NodeA run the command /usr/sbin/rsct/bin/dhb_transmit hdisk10
On NodeB run the command /usr/sbin/rsct/bin/dhb_receive hdisk10

C.
On NodeA run the command/usr/sbin/rsct/bin/dhb_read-p hdisk10-r
On NodeB run the command /usr/sbin/rsct/bin/dhb_read-p hdisk10-t

D.
On NodeA run the command “echo 1 | /usr/bin/dd of=/dev/rhdisk10 bs=4K skip=2 count=1”
On NodeB run the command/usr/bin/dd if=/dev/rhdisk10 bs=4K skip=2 count=1″
