TOPIC: SCSI

SCSI 5 years 1 month ago #543

Hi

I have both IDE and SCSI disks.

I can install Toorox on both types

I can boot from the IDE but am unable to boot from the SCSI.

Other OS's have loaded and ran from the same SCSI partition I am trying to use.

Any ideas please

Regards

John

Hi johnathan,

have you installed the bootloader into the MBR of your scsi disk?
Do you see the bootmenu when booting from scsi?

Hi Joern

Yes I think I have as I used the exact installation proceedure as for the IDE partition which boots with no problems.

System Info: 2 IDE disks hda,hdb 4 SCSI disks sda,sdb,sdc,sdd

Toorox installed on hdb2 and sdd3 when viewed in Ubuntu (on sda1) both partitions contain all the same files.

When booting, boot fails with message
VFS Cannot open root device “sdd3” or unknown block(0,0)
Please append a correct “root=” boot option here are available partitions

It then lists all my IDE partitions but does not list any SCSI partitions

I have used this partition for other OS's and other SCSI partitions for PclinuxOS and Debian

Below part of my grub menu all these and others boot

title Toorox 06.2009 (on hdb2)
root (hd1,1)
kernel /boot/vmlinuz root=/dev/hdb2 vga=791 nomce noapic lang=us
#initrd /boot/initrd.gz

title Debian GNU/Linux, kernel 2.6.26-1-686 (on /dev/sdd2)
root (hd5,1)
kernel /boot/vmlinuz-2.6.26-1-686 root=/dev/sdd2 ro
initrd /boot/initrd.img-2.6.26-1-686

Below THIS FAILS TO


title Toorox 06.2009 (on sdd3)
root (hd5,2)
kernel /boot/vmlinuz root=/dev/sdd3 vga=791 nomce noapic lang=us
#initrd /boot/initrd.gz

Looks like a missing (not build-in) scsi module.

Boot from the IDE disk, open a terminal and execute:
sudo lspci -v

Hi Joern

The print from your code, I have only included the SCSI part the disks are connected to the first controller

Kernel driver in use: aic7xxx
All SCSI host controller drivers were not built directly into the kernel.
So, the kernel cannot find your Toorox scsi partition after booting.
You can rebuild the kernel with a built-in aic7xxx module or make
a ramdisk.

Hi Joern

Thanks for taking the time to reply.

As I am a bit new to this I will stick with my Toorox on the IDE (which is working fine with all 6 drives) and use the SCSI for a different distro.
