Scsi(Pun0,Lun0) HP MSL6000 Series 0520 ( 20 MBytes/sec)
Scsi(Pun1,Lun0) HP Ultrium 3-SCSI G63W (320 MBytes/sec)
ReconnectController(0,0,0) : Status = Success
From this we gather that the Ultrium 3 Tape Drive is Pun1, Lun0.
At this point exit from the shell... returning you to the boot menu. At this point enter the boot configuration menu and boot from a file if you want a one time boot and look for result of your reconnect -r output... in my case it was Pun1, Lun0.
Boot menu showed the device as follows:
Device Path Acpi(HWP0002,PNP0A03,700)/Pci(1|1)/Scsi(Pun1,Lun0)
Other helpful commands would be:
devtree, devices, map
