The version of the management
applications might not be HA-

Drives are not reported in a
consistent manner.
Improper connections might
impact the order in which the
drives are discovered.
Make sure you are following the

The management application
does not report a VD or disk
group, but the VD or disk group
is visible to the OS.
The shared VD is managed by
the peer controller.
The VD or drive group can be
seen and managed on the other
controller node. Log in or open a
terminal on the other controller
node.
