Auto Unit Replacement
127
•
At least one INACTIVE CFG mirror image exists in the stack.
•
The MAC Address of the new unit is different from all the AMA of the
INACTIVE CFG mirror images in the stack.
The image restore process consists of the following steps.
Step
Action
1
Add a new unit to a stack:
a. If more than one INACTIVE CFG mirror image is in the stack,
select the one with the smallest unit ID for restoration.
b. Send the INACTIVE CFG mirror image in the stack to the new
unit. The INACTIVE CFG mirror image becomes ACTIVE.
c. The new unit saves the received CFG image to the flash drive.
d. The new unit resets itself.
—End—
For example, if you add a unit 5 (MAC Address 5) to the stack shown in
"CFG mirror images in the stack after removing the BU (unit 1)" (page 126)
,
the following occurs (see
"CFG mirror images in the stack after adding unit
•
The INACTIVE CFG 1 mirror image is copied to the CFG 5 image. Unit5
now has the configuration of unit 1, which is no longer in the stack.
•
The INACTIVE CFG 1 mirror image in unit 2 becomes ACTIVE.
•
The INACTIVE CFG 1 mirror image in unit 3 is removed.
•
The MAC Address 5 of the unit 5 becomes the new AMA of the CFG1
mirror image.
