Performing a factory reset
The purpose of a factory reset is to return a node to a clean, unconfigured, factory state. A factory reset discards all configuration data but does not affect the storage data. If you have a multi-node appliance, a factory reset only affects the node that you run this procedure from.
A factory reset resets the node to the current version. However, if you installed any security patches, they must be reinstalled after the factory reset.
After you perform a factory reset, you can also reset the storage if your appliance is not in lockdown mode. If it is in lockdown mode, storage reset is disabled.
Note:
If more than the tested number of Fibre Channel devices or paths are connected to the appliance, Cohesity recommends that you disable the ports or disconnect the devices before you begin this procedure. When the procedure is complete, reenable or reconnect them. You may need to scan the ports from the Fibre Channel interfaces page.
To perform a factory reset
- If you have a multi-node appliance, remove the node that you want to reset from the appliance. If you want to reset both nodes, choose a node to begin the procedure with and remove that node. See Removing a node.
- Log in to the Flex Appliance Shell from the node that you want to reset.
Note:
Cohesity recommends that you log in from the Veritas Remote Management Interface instead of an SSH session to perform a factory reset. To access the Veritas Remote Management Interface, refer to the initial configuration procedure. See Performing the initial configuration.
- Enter the following command:
system factory-reset
- Type yes to continue, and then press Enter.
Note:
Once you have started the factory-reset operation, do not perform any other tasks on the appliance until the reset is complete.
When the process is complete, you are prompted to restart. The factory reset is not complete until after the system is restarted. The system continues to run with the current configuration until after the restart is completed.
- Do one of the following:
To restart the node now, type yes, and then press Enter.
To restart the node later, type no, and then press Enter.
You can type the following command at any time to restart:
system restart
- When the restart is complete, the hostadmin user password resets to the default password (P@ssw0rd). Use the default password to log back in to the Flex Appliance Shell, then run the following command to change the password:
set user password
- If you have a multi-node appliance and want to reset both nodes, repeat the procedure on the other node.
After the factory reset is complete, do one of the following:
If you want to delete the existing storage data, perform a storage reset and then perform the initial configuration again to reconfigure your settings.
This option is not available if your appliance is in lockdown mode.
If you do not want to delete the storage data, you can recover the appliance with the existing storage data.
See Recovering storage data after a factory reset or a reimage.
If the node was never configured with the configure-console command, proceed with the initial configuration.
After the factory reset is complete, do one of the following:
If you performed the factory reset on only one of the nodes, add it back to the appliance. If the node was previously updated, reinstall the update after you add it back.
See Adding a node.
If you performed the factory reset on both nodes and want to delete the existing storage data, perform a storage reset and then perform the initial configuration again to reconfigure your settings.
This option is not available if your appliance is in lockdown mode.
If you performed the factory reset on both nodes and do not want to delete the storage data, you can recover the appliance with the existing storage data.
