    If you list the devices in the system, you should see a physical
    location ID as one of the columns. The example below is taken from one
    of our system audits for an obsolete system:

    lsdev -C | grep scsi

    scsi0 Available 00-00-0S Standard SCSI I/O Controller
    ascsi0 Available 00-03 Wide SCSI I/O Controller Adapter
    scsi1 Available 00-04 SCSI I/O Controller
    scsi2 Available 00-05 SCSI I/O Controller
    scsi3 Available 00-08 SCSI I/O Controller
    vscsi0 Available 00-03-00 SCSI I/O Controller Protocol Device
    vscsi1 Available 00-03-01 SCSI I/O Controller Protocol Device

    The number in the third column is your physical location information.
    If I recall correctly, the R30 numbers for your SCSI cards would be
    something like the following:

    1/5 should show as 01-05
    0/4 should show as 00-04

    You can then look to see if there are any other devices defined on
    those cards, such as an external tape drive, hard disk, etc. In the
    case of the adapter we used to have, the lsdev command below shows we
    had two hard disks attached to the adapter (with SCSI ID 0 and SCSI ID
    2 because of the "-00" and "-20" suffixes showing)

    lsdev -C | grep "00-04"

    hdisk0 Available 00-04-00-00 1.37 GB SCSI Disk Drive
    hdisk1 Available 00-04-00-20 1.37 GB SCSI Disk Drive

    Hope this helps. By the way, this is the location for the Service Guide
    for the R30 which may also give some insight:
