Recovering storage data after a factory reset or a reimage
If you performed a factory reset or a reimage and want to keep the existing storage data, use the following procedure to recover the appliance.
Note:
If you have a multi-node appliance, you only need to use this procedure if you performed a factory reset or a reimage on both nodes. If you only reset or reimaged one of the nodes, add that node back to the appliance. See Adding a node.
To recover the appliance
- Make sure that no new storage has been attached to the appliance that was not added to the appliance before the factory reset or the reimage.
- Log in to the Flex Appliance Shell. If you have a multi-node appliance and performed a factory reset on both nodes, log in to the node that you did not remove from the appliance. If you reimaged both nodes, select one of the nodes to perform this procedure on and log in to that node.
- Run the following command to reconfigure the network:
setup configure-network
Follow the prompts to enter the host network information.
Note:
Make sure that you enter the same settings that were configured before the factory reset or the reimage.
- Run the following command:
system appliance-recover
Warning:
If you have a multi-node appliance, do not run the system appliance-recover command from both nodes.
- Follow the prompts to recover the appliance.
Note:
If the recovery fails, you must restart the node before you retry the recovery.
- If you have a 5150 or a 52xx appliance, add the applications that you have instances of and the add-ons that are installed on them to the repository before you start the instances. See Adding files to the repository.
- If you have a multi-node appliance, add the node that you did not recover back to the recovered appliance. See Adding a node.
- If your appliance previously had security patches installed, reinstall them.
Note:
If the Flex Appliance Console was open before the appliance reset and recovery, open a new session after appliance recovery.
If any of the following features were previously configured on the appliance, note that the settings cannot be saved during a recovery. Make sure that you reconfigure them after the recovery.
Personal API tokens
Note:
The previous tokens still appear after the recovery, but they are shown as Invalid. Reissue the tokens to continue using them.
Predefined API tokens
Note:
The previous tokens still appear after the recovery, but they are shown as Invalid. Delete all invalid tokens and generate new ones.
The appliance metadata for single sign-on (SSO)
After a recovery, the appliance metadata file changes. Copy or download the new file and upload it to your identity provider (IDP).
See Adding an IDP.
Multifactor authentication for the shell
If multifactor authentication was previously configured, you are forced to reconfigure it the next time you log in to the shell.
Remote replication with self-signed certificates
If you have paired appliances that use self-signed certificates for communication, you must repair the connection after a recovery.
