How does it fail?

Comment 2 Thomas Zine 2004-07-01 13:36:22 UTC
grub will not be able to address any drives beyond 8 devices. If you
are hooking up an external array, grub will not locate the drive it is
installed on, due to drives being reordered. Starting the device.map
at the drive in which it is installed on (hd0) /dev/sdo also fails.
Claims invalid device.

Comment 3 Thomas Zine 2004-08-13 15:39:08 UTC
The latest ROM update from DELL for the PERC controllers modify the
load order on the PowerEdge 2650's. This appears to resolve the issue
for now. To duplicate you may have to back rev the PERC controller to
an older ROM. GRUB however, will still locate only 8 drives.

Comment 4 Peter Jones 2005-01-14 21:59:00 UTC
What screen is showing you the 8 drives?

Comment 5 Thomas Zine 2005-01-19 21:09:27 UTC
The source code. 
/dev/sdi through /dev/sdp in this case, grub cant recognize.

Comment 6 Peter Jones 2005-03-30 20:10:15 UTC
Please show me the output of "grub-intall --recheck" when it fails.

Comment 7 David Tonhofer 2005-03-31 16:40:03 UTC
I don't have the problem described here but I just came across this
remark in the Fujitsu-Siemens manual:

Linux drivers for PRIMERY servers, Revision 1.9, 23rd Aug 2004

pp 33 ff:

6.4.3. Booting fails on systems with GRUB and more than 9 hard disks.

Problem: The installation of the GRUB bootloader fails
Solution: GRUB supports only 9 (!) (sic) hard disk drives. Make sure no
more drives are specified in the GRUB device map. (...) Delete any lines
other than (hd0)-(hd8). Then re-run grub (...)
