I had installed solaris 10 on 440 on disk 0. I had done ufsrestore on disk1 from tape and then rebooted
Rebooting with command: boot disk1

This is a shot in the dark, but I think you need to change /etc/vfstab to use the new disk.

Thanks..........I did make changes in vfstab.

I not played with solaris 10 yet but when you restored your root, did you do a installbootblk?

also not sure whether you can still use probe-scsi at the ok prom level for solaris 10.

basically init 0 or stop-a to ok, then probe-scsi will list out the path_to_inst to scsi-devices like disks, cdroms and such

if it does, you can compares the error against the output. Or you can actually try to boot (specify the entire path) ie /pci@something ....

or

at ok prom do a

ok devalias disk2 /pci@something path ....

then boot disk2
