Hi everybody,

I have a failed RAID controller that I managed to "Ghost" while it was still running. Between this ghost image and the tape backup, I am hoping to get the system back on another hard drive, connected to the non-RAID built-in controller.
Here is some info:
- Openserver 5.0.5 (SCO)
- Compaq box with a dead Smart-2 controller and a living built-in SCSI controller
- ghost (Norton) image of the 18G RAID
- available 18G drive on the SCSI controller that works.

It will take some time until I get a used replacement controller, so I am trying to recover the system onto this other drive.

I was able to ghost the RAID image back onto the 18 G SCSI drive. Right now I am trying to boot it, using either the installation floppy, CD, or the emergency rescue diskettes I made before the controller died.

So far, any attempt to boot yields a Stage 1 failure when I try to boot directly the new drive or if I try the floppy approach and type in the root=hd(00) parameter it fails to see the boot partition.

It seems that the old drive was hd(40) and the new one hd(00), unless I messed it up.

Is there a better approach to this whole thing? Keeping in mind that I feel relatively confortable in Linux, but absolutely terrified of SCO.

Thanks very much.

And please keep in mind I am just learning GRUB so I may be way off base here, but can't you create a GRUB boot floppy (where it just boots into the GRUB command line) and go from there?

Also live CDs like DSL or KNOPPIX might be useful for either creating the floppy I just mentioned, or for trying to correct the booting setup on your hard drive. You can simply dd the stage1 and stage 2 files to your floppy or you can run the GRUB or LILO commands to (re)create your boot record. For the later, boot the live CD, mount your dead system's root partition (making sure not to mount it nodev or noexec), for example on /mnt/temp, and then execute the required commands using:

chroot /mnt/temp ...

Blackhole,

Thanks very mcuh for your reply.

I already tried the Linux approaach, but to no avail.
Neither Knoppix nor the boot CD's like UBCD were able to let me mount the HPFS UNIX filesystem.

Also, the bootloader on my system is the default SCO Openserver 5.0.5 boot loader, not lilo or grub, so there's a lot less documentation on the Net.

I came across aplawrence.com, a great site for UNIX, but my searches didn't yield anything useful to me.

Thanks again.
