Nuginy,   All drive firmware updates will require a reboot to complete. The update itself won't force a reboot, but the installation of the firmware update won't complete until it is rebooted.    Hope this helps.    
Hello,   I have one question about update physical disks on poweredge server.   Can i update firmware on this disks without shutting down virtual machines running of it or i must shutt down all VMs? I´m afraid about losing data or breaking RAID with this disks. We are talking about update disks through Vrtx Chassis Management Control or iDrace - Storage - Update - Upload new firmware - choose disks and Update. Thanks for answer my question. MZ.
