Perc3Di SCSI RAID + Adaptec 2810SA RAID = Fatal Grub Error?
I have a Dell PowerEdge 2650 with on-board Adaptec Perc3Di SCSI RAID ontroller (mirrored 18GB drives for OS). It also has an add-in Adaptec 2810SA 8-channel SATA RAID card. After installing FC3, and installing GRUB to the MBR of the mirrored 18GB drives for OS, when I boot the system, I get "GRUB Loading Stage2Read Error".
The Dell system and both RAID controllers were updated to their latest BIOS versions prior to installing the OS. I even tried (to no avail) booting into rescue mode, chrooting, and running: "grub-install /dev/sda". When I remove the add-in card from the system, grub works perfectly off of the on-board Adaptec Perc3Di SCSI RAID controller (mirrored 18GB drives for OS). I don't think the latest Dell BIOS for this machine has the provision to boot from add-in cards first, or to prioritize add-in cards after the on-board devices. I do know that the SATA add-in controller definately comes up first after POST before the on-board SCSI controller's BIOS. As suggested by various people, I booted the system into rescue mode using the install cd. Once booted, I chroot'ed, then ran: grub grub> root(hd0,0) grub> setup(hd0) This command did not return any errors. All output looked successful and normal from my experience on single-disk systems. /boot/grub/devices.map, fdisk -l, and grub tab expansion output all confirm that /dev/sda is indeed (hd0), and root is definately (hd0,0). By the way, I also verified that /dev/sda1 is bootable, and that /dev/sdb1 is not bootable. Now, when I boot the system, instead of getting a grub stage 2 error, I get a grub stage 1.5 error. Any help would be greatly appreciated. |
Didn't the GRUB manual link I gave you over at fedoraforum.org help you with that 1.5 error message you got?

Unfortunately, no. Thanks for the link anyway.
