4.12 Update TotalStorage DS300 and DS400 firmware

Two different firmware images can be stored on a DS300 and DS400. During
boot of the controller, one of the images can be selected by pressing 1 or 2 for
the first or second image. One firmware image is active and used to run the
controller and the other is passive. Only the passive firmware image can be
overwritten during a upgrade.
Note: The firmware update can be performed during normal operation. There
is no danger because the update process does not restart the DS300 or
DS400.
After the update is performed, choose a safe time for a reboot of the DS300 or
DS400. After the reboot, the DS300 and DS400 will load the new firmware image
because the update process sets the next boot image to the updated image
number.
Firmware of the DS300 and DS400 can be updated with the ServeRAID
Manager or over the CLI.
