Thank you very much for this tidbit of information. I had a similar error but from doing something completely different.
After successfully building a s10u6 Ultra 60 on ZFS boot with mirrored drives, I rebuilt disk0 with Solaris 8 to do some testing. When that was completed, I tried to 'boot disk1' from the OBP and was presented with this error: Rebooting with command: boot disk1 Boot device: /pci at 1f,4000/scsi at 3/disk at 1,0 File and args: SunOS Release 5.10 Version Generic_137137-09 64-bit Copyright 1983-2008 Sun Microsystems, Inc.

Resetting ... After 'boot net -s'ing the system and reading this message thread, I did the following: zpool import -f -a zpool list zpool export rootpool init 0 boot disk1 And the system booted just fine.
