Removing a node
Use the following procedure to remove a node from a multi-node Flex appliance.
Note:
If your appliance is in lockdown mode, removing a node also removes the lockdown mode on that node. This change does not go into effect until you physically disconnect the removed node from the shared storage shelves.
To remove a node
- From the Flex Appliance Console, make sure that there are no instances running on the node that you want to remove. Use the System topology page to view all of the running instances and relocate them as necessary.
- Log in to the Flex Appliance Shell on the node that you want to keep in the appliance. Run the following commands and check which node the
infra_svc
andrep_svc
services are running on:support shell
hagrp -state | grep infra_svc
hagrp -state | grep rep_svc
- If either service is running on the node that you want to remove, run the following command to move it to the other node:
system ha-service migrate service=<service> node=<node hostname>
Where <service> is either infra_svc or rep_svc, and <node hostname> is the hostname of the node that you do not want to remove.
Rerun the support shell > hagrp -state commands to check the status of the migration.
- Once you have verified that the services are no longer running on the node that you want to remove, run the following command to remove it:
setup remove-node
Follow the prompts to remove the node.
Note:
Do not perform any other tasks on the appliance until the remove-node operation is complete.
- When the remove-node operation is complete, disconnect the removed node from the shared storage shelves.
- If you plan to add this node back to the original appliance or use it in another Flex multi-node appliance, you must first perform a factory reset. See Performing a factory reset.
