An administrator has installed and configured AIX and PowerHA 7 on multipath vSCSI disks.
There are two VIO Servers, and both are accessing the same SAN storage system. The

expected?

A.
Delete the rootvg disk devices using the rmdev command.

B.
On both VIO Servers .remove all rootvg disk mappings for one node.

C.
Perform a quick system shutdown using the halt -q command on one node.

D.
Use the HMC to halt one of the VIO Servers which supports the primary MPIO path
