OK here it is with the fixed ofpath... rbthomas@kmac:~/tmp/usr/sbin$ ./ofpath /dev/sda /ht@0,f2000000/pci@5/k2-sata-root@c/@0/@0 rbthomas@kmac:~/tmp/usr/sbin$ ./ofpath /dev/sdb /ht@0,f2000000/pci@5/k2-sata-root@c/@1/@0 rbthomas@kmac:~/tmp/usr/sbin$ ./ofpath /dev/sda1 /ht@0,f2000000/pci@5/k2-sata-root@c/@0/@0:1 rbthomas@kmac:~/tmp/usr/sbin$ ./ofpath /dev/sdb1 /ht@0,f2000000/pci@5/k2-sata-root@c/@1/@0:1 All seems well on this machine...
