Figure 18

CFG mirror images in the stack after removing the BU (unit 1)

As shown in Figure 18 "CFG mirror images in the stack after removing the BU (unit 1)" (page 59):

•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 stack’s NBUs.

•The CFG 2 mirror image is created in unit 3. Unit 3 becomes the next TEMP-BU in case the current TEMP-BU is removed.

Restoring a CFG image

Restoring a CFG image is a process that overwrites the CFG image of a new unit in a stack with an INACTIVE mirror image stored in the stack.
