Update
You can schedule a time for a firmware update. A firmware update will always include a reboot.

After selecting the certificate file, UI will validate whether the certificate is valid.
Click the "Check" button to view the CAs that have been installed on the CacheDrive.

You can sort SMB connections by memory usage or by CPU usage. You can filter connections by username, share or client machine. You can select one or multiple connections to terminate. You can kill all connections to a share, or all connections from one machine.

Reboot
Rebooting the device may help resolve some temporary issues. You can also set a schedule for reboot time.

Shutdown
You can shut down the CacheDrive with a schedule.

Delete
If you want to delete a device that is still performing jobs, a prompt will appear.
- While Migrate, Duplicate, Clone, Hot standby, or Recovery jobs were in progress. By selecting the prompt and entering the device name, the device can be deleted whether it is online or offline, and the job will also be deleted.
- Limitation: If the device is the source gateway of a Clone job, deleting the device will not automatically delete the Clone job. The job needs to be deleted manually.
- While a Multicloud job was in progress, deleting the device performing the job was not supported. The prompt indicates the needs that to contact Morro Support to switch the task to another device and try again.
