Here is a link for the S100 documentation for further reference: [URL] You have a couple choices in the Ctrl R bios: 1. Rescan the drives  To perform a rescan, select Rescan Disks from the Main Menu field and press . (The activity indicator, in the information field at the top of the window, spins while the physical disks are being polled).  The Rescan Disks option rescans all the channels, searches for new or removed physical disks, and re-reads the configuration information from each physical disk.    NOTE: Sometimes when a physical disk has failed, it can be brought online through a rescan.   2. Set it as a hotspare and let it rebuild  3. Swap virtual disks.   According to the manual, the boot disk has to be 1 in the boot order.   Regards,
I have a new T110 II with a Perc S100 and 2 drives in a mirrored array. This morning the server wouldn't boot up - the dreaded 'Windows unable to find boot drive'. I unplugged one of the drives (HDD 0) and the system booted up okay. If I plug the other drive back in the system fails to boot.  In this case how do I rebuild the mirror on the failed drive? Just so you are aware the failed drive is physically okay and passes all hardware tests - it appears as though I have a software corruption that fails on boot. Dell have suggested that I format the drive in another machine and put it back into the array - that seems a bit clumsy. Is there no way I can force a rebuild on the machine itself? Thanks for any help.
How do I rebuild a corrupt drive on the Perc S100?
