ISE Node Deregistration Issue

[Michael Conroy]

I recently de-registered an ISE 2.2 node but it is still appearing in the deployment as a standalone node.  Is there a way to remove this node?

If you desregister then it shouldn't show in the pan. If you to login to
deregistered node what do you see in deployment

[Michael Conroy]

Exactly.  I was expecting it to disappear from the deployment within the PAN but strangely, it hasn't.    When I log into the node that was de-registered, it is correctly listed as a standalone.

Ok. Seems a bug pattern. Try to open a ticket with tac. Also try to move
from 2.2. Its the worst in 2.x series. 2.3 is much better

Thanks Mohammed.  I was actually in the process of moving the ISE VMs to new servers that will support migrating the deployment to 2.3.  In any case, I restored a recent backup, deregistered the node again and this time everything worked.  Appreciate the help.
