CFG mirror images after removing unit 4
Removing a BU
When you remove a BU, the TEMP-BU assumes the
role of the BU. Because all the CFG mirror images of the NBUs reside in
the removed BU, the TEMP-BU mirrors all the CFG image of the NBUs
in the stack.
After you remove the BU from the stack shown in
the stack after adding unit 4" (page 124)
, the TEMP-BU (unit 2) must mirror
all the CFG images in the stack (see
"CFG mirror images in the stack after
removing the BU (unit 1)" (page 126)
). The feature also ensures that the
stack always has two copies of an INACTIVE CFG mirror image.
