New to SCO Unix, need help desperately

[Annex]

I have installed a new SCSI hard drive into a server where its old SCSI is slowly dieing. It is running SCO Unix (what version I dont know, 1997 is the date). Anyhow, I know nothing about unix, I only have some knowledge of linux. Do I need to format/condition the drive first within SCO Unix before it can be used? I dont know how to do that, so I went ahead and tried norton ghost anyhow and cloned the old drive to the new. That did work, and I can start SCO Unix on the new hard drive, but when it runs it stops with the following error:

G hd_config
Warning: hd: no root disk controller was found
H iinit ime Loadable Driver may be required G drain 8042
Panic: srmountfan - Error 19 mounting root dev (1/42)
Error 19 opening dumb dev (1/41)

I believe I need to login as root, possibly su aftewards, and then modify one or more config files to have SCO Unix properly recognize the drive and mount it. I would really appreciate some help with this problem asap.

Have you changed the SCSI adapter ?

No the SCSI Adapter (onboard the motherboard actually) was not changed. No other hardware was changed other than me adding the new SCSI drive. The old drive is a 9gig, the new one is a 36gig.

BTW, your new disk must have SCSI ID=0

Ok its on ID 6. Do I have to change it on the drive with jumpers or will the motherboard have an onboard scsi bios I can access to change the ID?

And once I get this changed (monday), what will I need to do with SCO Unix regarding formatting the drive (if I need to do so), and mounting it properly?

 

[PHV]

Usually you change the Id with jumpers.
If the 9Gb drive is still connected, you have to change their Id.
If the ghost cloning was successfull then doing nothing will probably let the system running OK with your new drive seen as a 9 Gb one.

Ok the old and new drive, neither has any jumpers installed, so I thought it was normal for the new drive on its own to get whatever ID the scsi controller assigned to it. Why it wouldnt assign it ID 0 is beyond me since it is the only SCSI device in the system.

Assuming I dont want to short change the customer by 27 gigs or so, how would I go about formatting the drive so the whole thing is accessible by the OS and then copy over everything to the new HD?

And once all 36 gigs are accessible and the files copied over, what must I do to the OS to get it to mount the new drive properly?

 

[Annex]

Also according to the drive specs, if no jumpers are installed, it should default to ID 0. So I think I only saw ID 6 when I had the two drives installed and I was doing the ghost. Afterwards when I only had the new drive hooked up it SHOULD have been ID 0.

I know nothing about unix
I don't recommend you go about formatting the drive and reinstalling the Os (and probably some apps I presume).

It is because the SCSI controller takes whatever the human sets it up to be.
PHV has recommended that you not reinstall. You reinstall the OS and then you have to install the patches, then you have to create the users, then you do the printers, then the backup device, then the applications. Unix isn't a plug and play operating system. It takes work, even for those who have experience. My first one took 5 weeks to get right.

Ok I DONT want to reinstall. I want to ghost/duplicate the old drive onto the new drive, and get SCO Unix to work on the new drive (which it does not, Error 19). The reason I want to format the new drive first is because it hasnt been formatted, so only the first few gigs which norton ghost copied over contain a file system. The rest of the drive is unformatted. So what I want to do is format the drive with the proper file system, then ghost/duplicate the drive. Regardless, I really need help in getting SCO Unix to work on the new drive.

 

[PHV]

which it does not, Error 19
This is simply, I guess, because the kernel look at SCSI Id 0 for the root drive and not at Id 6.

It is not ID 6, it is ID 0, I had the client verify it. It was only ID 6 when I had both scsi drives connected so I could ghost the old drive. Sorry about that confusion.

If the old system is still operational and you can get on as root, uname -X (if memory holds true) will give you the version you are running. Or more /usr/admin/messages if it exists will show a series of splash screens of successive bootups with version shown. Delete key wiii exit the more.
Usual way would be to run fdisk after the system is working and create another partition and format it, then create a filesystem on it, then attach it into the existing system.
Another help resource is A.P.Lawrence web site. Or a search for pcunix will probably show it.
It will probably help if you have the emergency floppies to do some of the filesystem cleaning.
