A customer has installed a Hitachi Unified Storage (HUS) system with only port 0A connected to a Linux server. There is a video streaming application running on the server. You have to perform a firmware update using SNM2. What will happen when the update is started?

A. The Linux application will continue to function non-disruptively.

B. The Linux server will time-out because there is no alternate path.

C. The firmware update process will abort if the HUS does not have at least 5 seconds of no I/O activity on port 0A within 5 minutes.

D. The firmware update will fail because the HUS active/active controller feature checks for alternate pathing.
