SSSU Command Reference
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.
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.
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.
NAME=
This is the new name for the specified DR_GROUP.
SUSPEND
Stops replication of data from the source to the destination. This causes the same behavior as if the connection failed.
NOSUSPEND
Allows replication of data from the source to the destination to resume. This causes the same behavior as if the connection was restored.
WRITEMODE=
Defines the I/O interaction between the destination and source side. Possible values are synchronous and asynchronous.
