Comment:

I have an ultra60 with an external cdrom drive.
I do a probe-scsi-all and the cdrom is recognized at
/pci@1f,4000/scsi@3,1 target 6 unit 0
My other scsi devices are at
/pci@1f,4000/scsi@3
When I perform a probe-scsi the cdrom dr does not appear.
How do I get the system to boot off this cdrom drive?
I do a boot cdrom and I receive
can't open boot device.
Any suggestions?

Is the scsi ID of the external CDrom set to 6 ?

Thanks for your responses. I have done a reset-all without any change.
The scsi ID is set to 6.
Any thoughts

I will assume the CD in your drive is a bootable solaris cd that hasn't been damaged. It is possible that someone has changed the nvram settings for the cdrom alias to a different ID. Instead of typing
boot cdrom
you can specify the whole device id, the information that shows up about the device while your machine boots. pci@1f,4000/scsi@...

I attempted the boot using
boot /pci@1f,4000/scsi@3,1/
I now get boot load failed
I moved cdrom drive and media to an old sparc 20 and booted from the cdrom ok

If I were to boot one of these sbus machines with scsi the command is
boot /sbus@1f,0/espdma@e,8400000/esp@e,8800000/sd@6,0
see if you see something similar.
stop-n should reset the nvram to the default settings and would probably restore the cdrom alias if it had been changed.

I tried unsuccessfully. I do a show-devs and I don't see anything for sbus. I will keep plugging and thanx for all your suggestions.
Should anything else pop into your head please post for me. Thanks again

Ran into this myself.
Did the following and got it working:
1. probe-scsi-all
Locate your cdroms scsi "Target" for instance, 5
2. running "boot cdrom" might show something like this
/sbus@1f,0/espdma@e,8400000/esp@e,8800000/sd@6,0
The one thing that is important is the "sd@6".
The "Target" number of your cdrom and the sd@ should match.
For instance, my scsi device was set to target 5, so I booted from sd 5 instead of 6, like:
boot /sbus@1f,0/espdma@e,8400000/esp@e,8800000/sd@5,0
The /sbus or /pci "path" will likely be different from the one listed above. Make sure you specify the correct path or you will continue to receive errors.
If all goes well, then you can modify your eeprom settings with the nvalias command. Modifying the eeprom settings with devalias is temporary and will only last until the next reset.
