the disk upgrade is done using the USM (Unisphere Service Manager). USM will download the correct disk firmware. There is no external link for the disk firmware.  USM will indicate if the disk firmware is on-line of off-line. I believe that all disk firmware upgrades are now on-line, but I can't be sure about all of them.  glen
