grub hangs when adding sata disks
Hi,
My current system works fine, a poweredge 1800 with 2 sata disks on a onboard controller, configured in RAID. Grub boots fine everything is ok. Here is the working menu.lst
title Red Hat Enterprise Linux AS (2.6.9-34.0.1.ELsmp)
root (hd0,0)
kernel /vmlinuz-2.6.9-34.0.1.ELsmp ro root=/dev/VolGroup00/LogVol02
initrd /initrd-2.6.9-34.0.1.ELsmp.img
I've added this PCI controller:
06:03.0 RAID bus controller: Promise Technology, Inc. PDC40719 [FastTrak TX4300/TX4310] (rev 02)
Subsystem: Promise Technology, Inc. PDC40719 [FastTrak TX4300/TX4310]
Flags: bus master, 66Mhz, medium devsel, latency 88, IRQ 10
I/O ports at cc80
I/O ports at c800
Memory at df7ff000 (32-bit, non-prefetchable)
Memory at df7c0000 (32-bit, non-prefetchable)
Expansion ROM at df800000 [disabled]
Capabilities: [60] Power Management version 2
I've compiled the module, and inserted it, until here, no problem.
Now if I add 2 new seagate SATA HDD to this controlller, the controller BIOS will detect them and mark them as working. BUT, if I add them to a RAID, or a JBOD, then the system hangs after grub stage 2. It hangs just before I should read "uncompressing kernel", it just echoes the grub lines from the menu.lst.
I cannot boot a redhat in rescue mode, I'm stuck on a black screen with a blinking cursor, just after I type "linux rescue" at the prompt. I can boot a knoppix with kernel 2.4, but I only see sda after the boot.
There is no big options in the system bios, and I shouln't be making any changes here, since I just want to add 2 storage hdd's.
Using grub in command line generally causes grub to crash, or hang, I'm not sure. I get no results from a "geometry (hd1,0)" or "find /boot/grub/menu.lst".
Someone has any idea ?
