Install SCSI hard disk on SCO Unix V/386 1

[Ryerson]

Hi,
Do anyone online can help me to install a SCSI hard disk on a SCO unix V/386 PC?

My SCO unix V/386 hard disk crashed and I try to reinstall the system.I used the boot and root floppy to startup the system but the SCO unix system can't detect the new hard disk. After the system startup, I used command " Fdisk" to format the new hard disk, but system said no such drive.

Thanks

Do you have the original install disk and cd? The root & boot won't be enough by themselves to do a reinstall.
What kind of SCSI controller are you using, and did it come with a driver disk for unix?
Support for SCSI controllers , other than the ones built into the install set, are used with the aid of BTLDs, boot time loadable drivers, called at boot time to access the controller and root hard drive during original install ,and then loaded into the kernel near the end of install. Ed Fair

Any advice I give is my best judgement based on my interpretation of the facts you supply.

Help increase my knowledge by providing some feedback, good or bad, on any advice I have given.

Is it possible you have this new disk at a different SCSI ID? Normally it should be 0- but some new drives come set to 6.

Most SCSI controllers have some sort of BIOS level diagnostic capability- for example, with Adaptec you hit CTRL-A when it tells you to.

If THAT can't see the hard drive nothing else can.


Have you considered that maybe there was nothing wrong with the old drive and it's actually the controller that is defunct?

And of course as Ed said, if this is not a supported controler, you need a btld or a boot disk that has the proper driver in it.

BTW, Ed said above that root and boot aren't enough to do a reinstall.

That's not necessarily true. If properly made (that is, the disks have the necessary tools on them), AND you have a complete backup tape, you certainly can reinstall from that.

Also, if you are lucky enough to have root and boot from one of the Supertars (

) , not only is everything you need on the disks, you even get programs to help you recreate the system without having a clue how to do it yourself
