  Nimbus2018, I suggest that any time you are working with the Raid hardware it is a good idea to have a complete back up, just to be safe. That being said I don't believe you have anything to worry about with the update, although I would suggest that you start by updating the servers BIOS, iDrac, and the raid controller. Then after those I would update the drives firmware.  Now just a side note, with the BIOS and iDrac let me know what version they are on, this is because if they're really far behind in updates then jumping to the most current can cause issues.  Let me know how it goes and what you see.
Hi All, I've got a pair of R730xd servers which contain 24 x Seagate ST91000640SS 1.0TB drives. The disks are configured into a RAID5 and RAID10 volume with a disk 0:1:9 configured as a global hotspare. OME is reporting that both servers require a hard drive firmware update. It's showing the message "Disk 0 in Backplane 1 of Integrated RAID Controller 1" and references the package SAS-Drive_Firmware_M2P11_WN64_AS0D_A00.EXE. Will this firmware update preserve the data on the drives? I just want to check it's safe to run as I really don't like the idea of rebuilding the server and restoring from backup! Many Thanks...
