Removing a Node from a Stack

To remove a node from a stack, follow these steps:

Determine if the target node to be removed is using the SummitStack-V feature by issuing the show stacking stack-ports command.
Examine the Select column to see whether the target node is using alternate (non-native) stacking ports.
If the target node is using alternate stacking ports, do the following:
1. Log into the target node and issue the command: unconfigure stacking-support
2. Log out of the target node.
  
  Note
  Do not reboot the target node at this time.
Log into the master node.
Delete the target node stacking configuration by entering the following command:
unconfigure stacking {node-address node_address | slot slot_number}
Reboot the target node by entering the following command:
reboot [node node-address | slot slot-number]

When the node reboots, it detects that the configuration file selected is a stacking configuration file (see Stack Configuration Parameters, Configuration Files, and Port Numbering). It de-selects the configuration file and uses the factory defaults.
Disconnect the node from the stack, and redeploy it as needed.
