Removing an appliance from a stack
When you remove an appliance from the stack, the capture data on the appliance is retained. You can run local searches on the appliance to access the data.
Procedure
To permanently remove an appliance from a stack, select the appliance and click
Remove in the STACKING widget.
Note: You cannot remove the Stack Controller until all Stack Nodes are removed from a stack.
What to do next
Physically remove the cabling from the appliance, and re-cable the stack ring. You may see temporary cabling errors while stack connectivity is re-established.
