DESCRIPTION
nas_mview retrieves MirrorView/S cabinet-level information,
initializes the source and destination Celerra Network Servers for
MirrorView/S, activates a failover to a destination Celerra, or
restores the source site after a failover.
MirrorView/S is supported on a Celerra Network Server attached to
a CLARiiON CX-Series storage array serving as the boot storage, not
the secondary storage. nas_mview must be run from a Control
Station in slot 0; it will report an error if run from a Control Station in
slot 1.
nas_mview must be issued as root from the
/nas/sbin
directory.
For-init and -info, you can log in as nasadmin and su to root; for
-activate
and -restore, you must log in to the destination Celerra
Network Server using the remote administration account (for
example, dradmin) and su to root.
