Hi Alexey,

There is a red 'eject' button on in the cluster menu alongside the table of control planes.
You can only eject nodes that are currently followers.

Regards,

Phil.

Hi Phil
I cant see red 'eject' button it in GUI. I see just "shutdown" "restart" & "rebalance APs". 3.5.1.0.862ver

unknown

"shutdown" = 'eject' or not ?

No, there should be eject. Can you please attach a screenshot?

Hi Alexey,

You can also delete the Follower from the CLI (On Leader) as below:

SZ-100Leader# show cluster-state (to get the Follower node name)
SZ-100Leader# config
SZ-100Leader(config)# no control-plane

I haven't checked this in 3.5.1 version, but tested on later releases.

So, if I will demontage the failover SZ100 for change it on the NEW one (New RMA SZ100 whould be wizzard whith the same tunes to join to exist cluster), should I delete the Follower from Cluster BEFORE switching off old SZ100?

Hi Alexey, If I understand correctly, you are trying to add the SZ-100 to a new Cluster. If yes, then you will be doing a factory reset before joining it to a new Cluster.

Hi
Of course, Sanjay, I had done the factory reset before wizzard.
Yes, I will try to add the new SZ-100 to the existing Cluster.

The limitation in my LAN: I can not give new ip address to new SZ100.
The wizzard possible only with the same ip address with old failover SZ100 which will be switching off.

I just want to understand clearly what should I do whith failover ControlPlane.

SZ-104_3.5.1.0.862. It works.
Here is short How_2_Do for RMA change one SZ-104 in working cluster:
1.Make sw versions equal in the RMA, Leader & Failover SZs.
2.Swith off "failover" SZ (which is "bad" and need 2 be removed) from cluster by CLI in the leader ((config)# no control-plane ). Wait several minutes to dissappoint the removed SZ in Leader GUI (page "system"/"cluster").
3.Now switch off "bad" failover SZ from network by power or/and links.
4.Plug on the new RMA SZ whith patch of "bad" failover SZ instead the "bad" failover SZ.
5.Wizzard new RMA SZ with the same tunes of "bad" failover SZ (include ip address).
6.Enjoy.
