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
service is running on:support shell
hastatus -sum
- If the
infra_svc
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=infra_svc node=<node hostname>
Where <node hostname> is the hostname of the node that you do not want to remove.
You can check the status of the migration with the following commands:
support shell
hagrp -state
- Once you have verified that the
infra_svc
is not 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.
