Can you update hard drive firmware from within Windows OS?

We are replacing a failed 36GB SAS drive in a RAID5 array with a replacement that's several firmware levels below the working drives and wish to bring it up to the level of the others.  Must this be performed offline?  The box is a HP Proliant DL360 G5 and the drive is HP model DG036A8B53.  OS is W2K3.  The system admin says we need to perform the update offline but HP's site does not indicate this is necessary.

Looks to me like, the download is an iso image. Usually, you would boot to this DVD which has all the firmware updates on it. Your system admin would have the right of it. The drive mounted would prevent the update of the firmware.

There are drives that support online firmware updates, but they are not common.  I don't know what HP would call them ... Dell calls them DUP-Enabled drives.  They are not available in every model and are usually pretty expensive ... odds are, you will need to do it while offline.

The disks can not be updated online, as the tail end of the firmware update requires the HDD to reboot it's O/S, for the new firmware to kick in.  

HP's site did not indicate that it can't be updated online for the same reason that they didn't indicate if the update can be done on a Tuesday.  These disks are commercial Seagate family with nearly off-the-shelf firmware that brands the HDD as HP.
