How to reformat a dead SCSI disk from RedHat installation CD?


My RedHat - based Dell server suddenly died. The native Dell boot did indicate the presence of the drive but no partition (=drive letter) was found and it offered no way to re-format and partition that drive.

I ran the RedHat Enterprise V.3 installer several times, but it never gave me a prompt from which I could have run any command. First question: how to get to the point at which I can interact with the installer?

Second question: Provided I get a prompt, how should I format the disk, create a bootable file system, and mount it?

Thank you,
-Pierre

Does this 'RedHat Enterprise V.3 ' mean RHEL3 ? If so that's been out of support for a very long time.
See here for support lifetimes http://www.redhat.com/security/updates/errata/.
Its possible that installer is too old to recognise the/include a device driver for the disk.

In any case, RHEL install will offer a GUI or pseudo-gui partitioning option and that will automatically format as reqd.
No need to pre-format.

It might help if you could post the basic HW specs of your box.

Hi Chris,

The computer in question is about 30 miles away and I may go out there tomorrow or the day after. In any case, I checked w/ RH and, indeed, there is no easy support for EL3. So, here is what I could do: lift the disk out of the machine, reformat it on another computer that can create a NTSF file system (this is what I will need), and then go back and try to run the EL3 installation disk once more. Maybe it will let me interact once it can recognize a disk. I also have an external RAID on that computer but I don't want to install RH on it.

Cheers, try to stay cool in your summer (it is a balmy winter in the SF area),
-Pierre

I've personally used Puppy Linux and it worked for me, but I was just moving files around from a bad hard drive. Recently I've used fdisk which ships with all newer distro's I believe, but that might be a good start for you troubleshooting the drive to even see if it's being recongnized by the computer.

You could create a live boot usb or dvd of Ubuntu 13.10 and use it's tools.

You could also use lsblk to get a nice view of what's connected to your computer.

To create a filesystem, you will need to use mkfs so type, man mkfs, for help

To mount use, sudo mount. Man mount, for help.

Good luck,
Chris

Why don't you use Centos instead if you don't want to pay for an up to date version of RHEL (latest is v6.5).
Centos is basically a free binary compatible clone; includes updates but not support.
Incidentally, RH have just announced they're going to get even closer with Centos if that helps.
