If you have a failed node in an ExtremeNetworks Summit virtual stack, there are some steps that must be followed in order to replace the node with new hardware.
- First, make sure sure your new node is the same firmware as the stack. It doesn’t have to be the latest, but it should match.
- Remove the failed switch and install the new switch in the stack
- Issue the command ‘disable stacking’ on the new switch and reboot
- Console into the master node and issue these two commands:
- ‘synchronize stacking node-address (MAC of the switch your adding to the stack)’
- ‘conf stacking node-address (MAC of the switch you are adding to the stack) slot-number (The next available slot #)’
- Return to the new switch being added and issue a reboot, but only on the new switch.
- When the switch is rebooted and back online, the switch will be added to the stack and ready to go.
- On the master, verify by issuing the ‘show slot’ command.
NOTE: I just tried these instructions and they didn’t work: The failed ‘node’ would not come on-line (it continued to say ‘Disabled’ when I did a ‘show stack’). I finally issued an ‘enable stacking node-address ‘ and rebooted that node. Then it worked fine.
NOTE 2: Another useful command so you don’t have to switch back and forth between nodes:
reboot node-address <address of node to be rebooted>
