Figure 4: CFG mirror images in the stack after removing the BU (unit 1)
As shown in
• 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
Restoring a CFG image overwrites the CFG image of a new unit in a stack with an INACTIVE
mirror image stored in the stack.
