Firmware Maintenance
Overview
This function performs the maintenance operation for the firmware that is managed in the storage system.
Firmware maintenance is performed to update the firmware version. The firmware can be applied after being registered in the Bootup and Utility Device (BUD).
There are two types of firmware; "controller firmware" and "disk firmware".
Refer to the following table to determine whether to stop the host I/O when applying firmware.

The [Apply Controller Firmware] function is automatically started at the date and time that are displayed in the information field according to the application mode that is used. When the application mode is "Update & Reboot", the storage system is automatically rebooted after the controller firmware is applied.
