Solaris 10 - system hung, and now will not boot

Question

I have a SunFire V240 with 2 73 SCSI disks running Solaris 10. Only the first disk has been formatted. The box was newly installed last week.
It had 2 zones set up on it and one of them was running a service out of it (called knowledgetree). I came in this morning (monday), and although I could ping the main server and the zone, I could not ssh to the box. I hooked up a console cable to the box, and there was nothing.
I then went to the OK prompt and typed boot.
It said
1} ok boot disk2
Boot device: /pci@1c,600000/scsi@2/disk@0,0:a File and args:
Can't open boot device
{1} ok
I then typed
{1} ok setenv auto-boot? false
auto-boot? = false
{1} ok reset-all
followed by
{1}ok probe-scsi
Target 1
Unit 0 Disk SEAGATE ST373207LSUN72G 045A
If I type the following I get the results below.
{1} ok show-disks
a) /pci@1c,600000/scsi@2,1/disk
b) /pci@1c,600000/scsi@2/disk
c) /pci@1e,600000/ide@d/cdrom
d) /pci@1e,600000/ide@d/disk
q) NO SELECTION
Enter Selection, q to quit: a
/pci@1c,600000/scsi@2,1/disk has been selected.
Type ^Y ( Control-Y ) to insert it in the command line.
e.g. ok nvalias mydev ^Y
for creating devalias mydev for /pci@1c,600000/scsi@2,1/disk
Does anyone have any ideas on what happened, or what I have to do to get the OS to boot again. I am a bit of a nubie when it comes to Solaris .... I am not sure what happened, or why all of the sudden the server will not boot.
Thanks for the help

Answer 1

Usually you can just do a "boot disk" or "boot disk1"
devalias will show you what actually devices the short alias map too.
It might be a faulty drive bay.
Try pulling it out of one and plugging it into another.
The do the probe-scsi again.
Then put it back into the first to confirm....
