Update: Sun Fire V65x Server with external scsi unit will not boot

[Adam Bisbe <bblp@bisbe.net>]

Now I know what it is, but not how to fix it:

There are 2 adapters, A and B, internal is B and external is A

on B I have 2 discs sda and sdb, sda is the boot disk,
when I connect an external box with a hard disk and a tape the external 
disk gets sda, internals get sdb, sdc.

As boot disk is now sdb, it boots and when it looks for filesystems it 
goes to sda disk which is not yet formated.

I have looked on both setups ( bios and scsi) but cant find how to 
change the order of scsi adapters.
I suppose that I can fix it on grub config?

thank you for your help
Adam
