Question
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. Hdisk10, 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?
Options
- AOn NodeA run the command /usr/bin/readvgda -V dhbvg -F status On NodeB run the command
- BOn NodeA run the command /usr/sbin/rsct/bin/dhb_transmit hdisk10 On NodeB run the command
- COn NodeA run the command /usr/sbin/rsctfbin/dhb_read-p hdiskl10 -t On NodeB run the command
- DOn NodeA run the command "echo 1 | /usr/bin/dd of=/dev/rhdisk10 bs=4K skip=2 count=1" On
