Hi Jason,

the machine powers up okay, self tests and all looks normal.

All drives spin okay, no error messages reported by the raid controller.
The "controller" sees all the drives on the SCSI bus and starts them
normally.

The only messages i get is "cannot find boot device" - F1 to continue, F2 to
try again..sort of thing after the whole startup process.

did a Ctrl-A at startup and the only thing i can see is that the container
is flagged as "dead" .

Tried to boot off floppy and it cannot see the MD device, in fact it cannot
see the hard disks at all.

Any help ? what sort of diagnostics are there?

Rgs, Davor
