Example 1:
The vxdisk command does not display HDLM devices but displays the sd
or ssd devices corresponding to those HDLM devices.
The vxdisk command displays the SCSI device c3t0d0, which
corresponds to an HDLM device, instead of the HDLM device c5t0d0.
Example 2:
The vxdmpadm command outputs a non-HDLM device, and the STATE
column shows ENABLED.
