I had an old Dell Precision 470 with 2 hard drives, a 250GB boot drive with Red Hat installed, and a 500GB hard drive with data on it. Both of these are SATA. The computer died and I have replaced it with a Dell T3500. I was hoping just to move the hard drives into this computer and let generic drivers take over until I make the necessary changes. Unfortunately, I get the following kernel panic message after POST:

VFS: Cannot open root device "Volume00/root" or 00:00
Please append a correct "root= " boot option

Right now the arguments to boot from the hard drive are:

ro root=/dev/Volume00/root hdc=ide-scsi hdd=ide-scsi

I don't know if this is enough information or not to help me, but does anyone have any ideas?

Judging by the Volume00 errors, I would guess it has something to do with the LVM setup on the hard disks. I'm guessing the drive identifier (hda, sda, etc) changed from one computer to the other and that the lines listed to boot the LVM no longer point to the correct spot. I don't have much experience with LVM though, so I'm probably not much help.

I'm not familiar with LVM, I will do some research on this.

I guess what I'm thinking is, put more simply, that if (for example) there was a floppy drive or multiple CD-ROM drives etc, they should appear in the same order to the new computer? Or is there more to it than that?
