Title: "Please Insert SCSI Disk 1 in Drive 1" during boot

Hi all, doing some forensic recovery of an old Cube, I came across a message in the boot process I'd never seen before:

Please Insert SCSI Disk 1 in Drive 1

This happens right during, or after, a clean FSCK outcome.  I'm booting this cube from a dd image of the original hard drive -- is it possible there's some hard-coded dependency on specific SCSI ID's or LUN's for the mach kernel?  (The device I'm booting from is actually a SCSI memory card reader, so it has a few logical unit numbers itself that could be confusing things.)

Anyone ever come across this message before?

What OS version is it? In pre-2.2 the OS was a bit finicky about disk geometry... you'd be better off doing a dump and restore after a disk-b instead of dd.

Definitely haven't seen that before.  The two main places where there are disk/partition dependencies are in the nvram boot string and in fstab.  If you're playing with topology, those two things may need adjustment.

The other things to think about is that you can mount the dd'd images in linux using loopback. Unless you need it to boot, that might be easier.

FWIW. With the MO drives, you get a similar message if you insert a disk, eject it from the command line/manually, and then insert a *different* disk.

I think I've tracked this down to the fact that I'm using a SCSI card reader, which (understandably) declares itself to the OS as a removable drive.  

Though counterintuitive, if you just eject the card and re-insert it, the OS seems happy...
