waiting for /dev/sda2 to appear


Hi,

I have a problem to boot from a SATA disk. The filesystem image was created by our customer and copied to the SATA disk. It is SLES 10.2.
When booting, "waiting for /dev/sda2 to appear" appears. The filesystem seems not to be corrupted, it can be mounted via a live CD. Here are the files I consider being useful for you.

menu.lst
Code:
timeout 10
gfxmenu (hd0,1)/boot/message
title SLES 10.2
 kernel (hd0,1)/boot/vmlinuz root=/dev/sda2  vga=0x314 splash=silent resume=/dev/sda1   showopts
 initrd (hd0,1)/boot/initrd
title Failsafe -- SLES 10.2
 kernel (hd0,1)/boot/vmlinuz root=/dev/sda2  vga=0x314 splash=silent resume=/dev/sda1   showopts ide=nodma apm=off acpi=off noresume selinux=0 nosmp noapic maxcpus=0 edd=off
 initrd (hd0,1)/boot/initrd
fstab
Code:
devpts  /dev/pts   devpts  mode=0620,gid=5 0 0
proc    /proc      proc    defaults 0 0
sysfs   /sys       sysfs   noauto 0 0
/dev/sda2 / ext3 defaults 0 0
/dev/sda1 swap swap pri=42 0 0
fdisk -l
Code:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         262     2104514+  82  Linux swap / Solaris
/dev/sda2   *         263        4209    31704277+  83  Linux
thanks for helping

Is your bios searching for the usb drive? If you simply have it in grub, you may have problems loading a kernel, and fall into a catch-22 type situation.

thanks for the answer. It is not a usb drive, it is a SATA drive. It is correctly recognized by BIOS.

Are the correct modules for reading /dev/sda2 available in an initrd or compiled into the kernel? It sounds like the sot of place you might stop> Have you tried google

thanks business_kid for your reply. How can I find whether the correct modules are available in kernel or initrd? We were given the disk from our customer for testing purposes, so I don't anything about the way they prepared the system.
Thanks.

OK, find out what fi8lesystem is on it. Reiser? Amiga? Solaris? fdisk -l usually lists the ID as a hex number. Note what it's called, and run through your kernel config to see
1. You can read the filesystem
2. you can read the partition

If it was made on a mac it could be awkward. Try and mount the beast.
