Replacing an AOS-CX VSF Stack Member (Same Model and Part Number)

Aruba Central allows you to replace a member of the AOS-CX VSF stack only if the switch model and part number are same. You can replace either the conductor, standby, or any other member of the stack.

Replacing the Conductor

To replace the conductor in the VSF stack, complete the following procedure:

1. Shut down the conductor member in the stack.
2. Wait for the standby member to become the conductor.
3. Replace the switch.
4. Toggle aruba-central disable and enable from the switch CLI.

   If this does not work, go to bash and restart hpe-restd service by running the systemctl restart hpe-restd command.

   switch# configure switch(config)# aruba-central switch(config-aruba-central)# disable switch(config-aruba-central)# enable

   OR

   switch# start-shell switch:~$ sudo systemctl restart hpe-restd
5. Switchover to the new conductor in the switch CLI.

Replacing the Standby or Other Members

To replace the standby or any other member of the VSF stack, complete the following procedure:

1. Shut down the member in the stack.
2. Configure the new switch and the VSF links to the new switch.
3. Renumber the VSF member using the vsf renumber-to command.

   For example, if the member ID of the old switch was 2, renumber the new VSF member to 2.

4. Move the VSF link DAC cable from the old switch to the new switch.
5. Verify the status of the Aruba Central after the new switch reboots.
6. Toggle aruba-central disable and enable from the switch CLI.
   switch# configure switch(config)# aruba-central switch(config-aruba-central)# disable switch(config-aruba-central)# enable

   OR

   switch# start-shell switch:~$ sudo systemctl restart hpe-restd
