Description Todor Tanevski 2005-12-14 08:32:03 UTC
the 2005.1 livecd works correctly. the system is correctly installed. 
the hard disk is within internal RAID. its name is /dev/cciss/c0d0, and
partitions which are successfuly created with fdisk and mounted as swap and ext3
are /dev/cciss/c0d0p1 (swap) and /dev/cciss/c0d0p2 :

root@livecd ~ # fdisk -l

Disk /dev/cciss/c0d0: 36.4 GB, 36414750720 bytes
255 heads, 32 sectors/track, 8716 cylinders
Units = cylinders of 8160 * 512 = 4177920 bytes

           Device Boot      Start         End      Blocks   Id  System
/dev/cciss/c0d0p1               1         246     1003664   83  Linux
/dev/cciss/c0d0p2             247        8716    34557600   83  Linux
root@livecd ~ #

after several iterations i got this grub.conf file which somehow boots the Proliant:

root@livecd ~ # mount /dev/cciss/c0d0p
c0d0p1  c0d0p2
root@livecd ~ # mount /dev/cciss/c0d0p2 /mnt/gentoo
root@livecd ~ # cat /mnt/gentoo/boot/grub/grub.conf

default 0
timeout 30

boot=/dev/cciss/c0d0
device (hd0) /dev/cciss/c0d0
root (hd0,1)

splashimage=(hd0,1)/grub/splash.xpm.gz

title=Gentoo Linux 2.6.14-r4
kernel /boot/kernel-genkernel-x86-2.6.14-gentoo-r4 ramdisk=8192 doscsi udev
initrd /boot/initramfs-genkernel-x86-2.6.14-gentoo-r4
root@livecd ~ #

after the 'unclean' boot process (there is something wrong in parts with the
display) i got to the point where something (presumably udev) tells me that
there is unkown root block device. i get the busybox shell and the /dev/ does
not have any reference to the /dev/cciss/ not to any other resembleing device
(i.e. scsi). there is however one disfunctional /dev/hda device file and off
course the /dev/ide/... cdrom . 

i had RHEL 3.0 U3 linux running happily on the machine without any problem.
unfortunately i did not saved the grub config before reinstall. 



Reproducible: Always
Steps to Reproduce:
1. Install form 2005.1 livecd.
2. configure correctly everything.
3. reboot.

Actual Results:  
failed

Expected Results:  
to reboot properly and the installed system to recognize the /dev/cciss/c0d0 as
the livecd does.

What version of udev are you running?
Do you have the proper driver for your disks built into your kernel, or as a module?

It sounds like your module is just not being loaded.
Comment 2 Todor Tanevski 2005-12-15 00:35:42 UTC
it could be. i made a 'genkernel all' kernel build. i have never done that
before in any other gentoo installation. i have done that exactly for proper
loading of all the modules i even did not know Proliant needed. i did not
controlled what and how is loaded. i think that the cciss module need to be
loaded. however, the grub has problems with detecting the (hd0) as
/dev/cciss/c0d0 anyway. it is the root problem. i found on other web page that
at least on one occassion the lilo did not help either with detecting it on
gentoo. grub device.map did not contained (hd0) entry at all. i had to add it
manually. this was fixed at grub bugs page a year ago. do i need to recompile
the kernel or initrd or add the cciss module to the /etc/autoload... file?

Comment 3 Todor Tanevski 2005-12-15 01:04:49 UTC
hello. i have read more on the issue in the gentoo forums. i think that the
problem with grub is separate from my own problem where cciss module most
probably is not not loaded AFTER boot. however i would say at the moment that if
this is to be pursued as a bug it is most likely to be configuration issue
within grub and not a bug as such in gentoo. 

to be frank - this should be closed. 

if you have good information how to overcome grub installation (grub-install
definitely not works) with Compaq Smart Array 5i (cciss) disks than perhaps this
should be mention as a warning or something within the gentoo installation handbook.

thank for your help!
