I have a Dell PowerEdge 2650 with on-board Adaptec Perc3Di SCSI RAID |
| 2 |
controller (mirrored 18GB drives for OS). It also has an add-in |
| 3 |
Adaptec 2810SA 8-channel SATA RAID card. After installing installing |
| 4 |
GRUB to the MBR of the mirrored 18GB drives for OS, when I boot the |
| 5 |
system, I get "GRUB Loading Stage2Read Error". |
| 6 |
|
| 7 |
The Dell system and both RAID controllers were updated to their latest |
| 8 |
BIOS versions prior to installing the OS. |
| 9 |
|
| 10 |
I even tried (to no avail) booting with a LiveCD, chrooting, and running: |
| 11 |
"grub-install /dev/sda". |
| 12 |
|
| 13 |
When I remove the add-in card from the system, grub works perfectly |
| 14 |
off of the on-board Adaptec Perc3Di SCSI RAID controller (mirrored |
| 15 |
18GB drives for OS). |
| 16 |
|
| 17 |
I don't think the latest Dell BIOS for this machine has the provision |
| 18 |
to boot from add-in cards first, or to prioritize add-in cards after |
| 19 |
the on-board devices. |
| 20 |
|
| 21 |
I do know that the SATA add-in controller definately comes up first |
| 22 |
after POST before the on-board SCSI controller's BIOS. |
| 23 |
|
| 24 |
As suggested by various people, I booted the system using the LiveCD |
| 25 |
and once booted, I chroot'ed, then ran: |
| 26 |
|
| 27 |
grub |
| 28 |
grub> root(hd0,0) |
| 29 |
grub> setup(hd0) |
| 30 |
|
| 31 |
This command did not return any errors. All output looked successful |
| 32 |
and normal from my experience on single-disk systems. |
| 33 |
|
| 34 |
/boot/grub/devices.map, fdisk -l, and grub tab expansion output all |
| 35 |
confirm that /dev/sda is indeed (hd0), and root is definately (hd0,0). |
| 36 |
|
| 37 |
By the way, I also verified that /dev/sda1 is bootable, and that |
| 38 |
/dev/sdb1 is not bootable. |
| 39 |
|
| 40 |
Now, when I boot the system, instead of getting a grub stage 2 error, |
| 41 |
I get a grub stage 1.5 error, even after additionally trying: |
| 42 |
|
| 43 |
grub> root (hd0,0) |
| 44 |
grub> setup --stage2=/boot/grub/stage2 (hd0) |
| 45 |
grub> quit |
| 46 |
|
| 47 |
My setup is |
| 48 |
|
| 49 |
On-Board Raid: |
| 50 |
/dev/sda (18GB Mirror) |
| 51 |
/dev/sda1 = /boot |
| 52 |
/dev/sda2 = / |
| 53 |
|
| 54 |
External SATA Raid: |
| 55 |
/dev/sdb (1.4 TB Raid5) |
| 56 |
(unassigned) |
| 57 |
|
| 58 |
CD-Rom |
| 59 |
/dev/hda |
| 60 |
