How do you clean up stacking config and port info after a stack member has been removed?

After removing a stack member by logging into the master node - and running "unconfigure stacking" {node address or slot number} then "reboot" {node address or slot number}.

The stack member you chose to remove will reboot and return to factory defaults.  However the master node still "thinks" there is a stack member and shows all ports as being present - present and disabled.

The status of the master (in this case originally a 2 stack)  when a show "stacking" is run - you see that it has "stacking enabled - master"

Port reports from Ridgeline and Netsight still include these ports in results.  

None of these ports show up as unused ports in Netsight....but it does display them in port details in capacity manager.

Hi Peter,

What's the output for show slot command?

I'm wondering about trying to use unconfigure slot <slot_number> if slot-2 still appears when using the command above.

unconfigure slot should take care of this, I believe.

Unconfigure slot was the answer.

Many thanks Henrique (and Brandon)...................................................................................

This is was how it was configured.
Slot-1 XXXXXSW01.2 # sh slotSlots    Type                 Configured           State       Ports
--------------------------------------------------------------------
Slot-1   X440-24p             X440-24p             Operational   24
Slot-2                        X440-24p             Empty         24
Slot-3                                             Empty          0
...................................................................................................

And now no slot info at all.  Config is also without phantom ports.

Thanks for all the help - PB

Was having the same problem.  I removed stack member 4, but the switch still thought it had something in that slot.  unconfigure slot 4.

Success.  Thanks, man.

How to remove a node from a stack

I have a stack of 3 and will be pulling out slot 2.  Will unconfigure slot 2 automatically have slot 3 move to slot 2?

No - you would need to make that change yourself. It would also require you to update the configuration to move items on slot 3 to slot 2.
If you decide to make this change, you will also want to make sure that slot 3 is master capable, otherwise you'll only have a master and standby node with no backup.

Note that if you do this, you will lose the config from the existing slot 3 (new slot 2). It's ports will need to be reconfigured.
