DETACH_VDISK=
Name of a source system VDISK to be removed from the DR Group. The
corresponding destination VDISK on the destination system is removed from the
DR Group but not deleted. The detached destination VDISK continues to exist as
an independent VDISK.

FAILOVER
Reverses the roles of the DR Groups; the source becomes the destination and the
destination becomes the source. This is used to both “fail over” to the destination
site and to “fail back” when normal operation is to be resumed.
destination becomes the source. This is used to both “fail over” to the destination
site and to “fail back” when normal operation is to be resumed.
FAILSAFE
When the connection between the source and the destination system fails, all
writes are immediately halted and none is reported as completing until either the
connection is restored or NOFAILSAFE is set.
writes are immediately halted and none is reported as completing until either the
connection is restored or NOFAILSAFE is set.
NOFAILSAFE
This is the default when you first create the DR Group. When the connection
between the source and the destination system fails, writes are directed to the log
until the connection is restored. At this point, the pending destination writes are
pushed across to the destination system. If the log becomes full, the system makes
a full copy of the source VDISK to the destination VDISK when the connection is
restored. Otherwise, the log resynchs the source and destination VDISKs.
