Internal Mirrored Groups (IMG)
You may create, edit and destroy IMGs from the system, as well as breaking, merging, adding and
deleting LUNs within the IMG. For detailed instructions on IMGs, refer to document number 96-
00165-001.
To display the currently created IMGs (Firgure 3-62)
,
enter command
MIRROR
.
The
MIRROR CREATE
command will create a new IMG in the system. The system will prompt you for
all the necessary information to create the IMG and indicate if the IMG was successfully added to the
system.
The
MIRROR DESTROY
command will permanently delete an IMG from the system. This will delete
only the IMG itself, but not the data on the individual LUNs.
Note that all Backup LUNs in the IMG must
be broken before a delete can occur
.
The
MIRROR ADD
command can be used to add additional Backup LUNs to the IMG after it has been
created. All data on the Backup LUN is destroyed and then it is data-synchronized with the Primary
LUN.
The
MIRROR DEL|DELETE
command will delete a broken Backup LUN from the IMG. All data on the
Backup LUN is preserved.
The
MIRROR BREAK
command can be used to break Backup LUNs from the IMG where the Backup
LUN will no longer be mirroring the Primary LUN. All data on the Backup LUN is preserved.
Parentheses surrounding a Backup LUN is an indication that the LUN is broken from the IMG.
The
MIRROR MERGE
command will add the Backup LUN back into the IMG allowing it to mirror the
Primary LUN once again. All data from the Primary LUN is copied over onto the Backup LUN so they
are again identical.
The
MIRROR PAUSE
command can be used to temporarily pause the merge procedure.
The
MIRROR RESUME
command will release the paused merge operations.
The
MIRROR STOP
command can be used to abort the merge procedure all together.
