Unit 2 becomes the TEMP-BU.
•
The CFG 1 mirror image (residing in unit 2) becomes INACTIVE.
•
A second copy of the INACTIVE CFG 1 mirror image is created in unit 3.
•
The TEMP-BU (unit 2) contains all CFG mirror images of the NBUs
in the stack.
•
The CFG 2 mirror image is created in unit 3. Unit 3 becomes the next
TEMP-BU in case you remove the current TEMP-BU.

Restoring a CFG image overwrites the CFG image of a new unit in a stack
with an INACTIVE mirror image stored in the stack.
Note: Restore a CFG image to a new unit happens only if you meet the
following conditions.
