NOTE
You can use interactive-setup to renumber the members in the newly merged stack. Refer to
on page 75 for more information.
The following examples show how stack merging works:
•
If a stack partitions into multiple stacks because of a connection failure, you can fix the connection and the stack
partitions will merge back into the original stack with no change to stack IDs because all stack IDs are distinct.
•
In a linear stack topology, the end units of the stack have only one stacking port configured. Before you can merge two
linear stacks, you must reconfigure the end units so that both ports are stacking ports.
Unconfiguring a stack
The stack unconfigure command is a runtime command that returns stack units to their pre-stacking state. When a stack unit is
unconfigured, its stacking flash is removed, and its startup-config.txt flash file is recovered. These actions apply to all units to
which this command is applied, regardless of the role of the unit in the stack.
When the stack unconfigure command is applied to the active controller, it removes stack enable from the runtime
configuration but not from the startup configuration. If you want to remove the stack enable command from the active
controller permanently, you must enter the write memory command after the stack unconfigure command.
When the stack unconfigure command is applied to the standby controller or a stack member (besides the active controller), it
removes stack enable from the recovered startup-config.txt file and resets the unit.
NOTE
When a stack member becomes a standalone unit after the stack unconfigure command, it could become a clean unit
if it had no startup configuration flash. When a clean unit matches the active controller’s static configuration, the active
controller integrates the clean unit into the stack. Thus, the standalone unit is reloaded to be a member of the stack.
Users can avoid this problem by disconnecting the member unit from the stack and issuing the stack unconfigure me
command on the unit to change it to a standalone unit.
To remove the configuration from the current stack unit, enter the following command.
device# stack unconfigure me
To remove the configuration from the current unit, including the startup configuration, so that the unit reboots as a clean unit,
enter the following unit on the stack member console.
device# stack unconfigure clean
NOTE
The stack unconfigure clean command can be entered only on the stack member console.
To remove the configuration from the entire stack, enter the following command on the active controller for the stack.
device# stack unconfigure all
To remove the configuration from a specific stack unit, on the active controller for the stack, enter the stack unconfigure
command followed by the stack unit ID as shown in the following example.
device# stack unconfigure 3
The example unconfigures stack unit 3.
