Mapping Logical Addresses to Physical Devices
Because there are no physical addresses below the SCSI port level, determining the
physical location of a disk, tape, or CD-ROM device requires some knowledge of
how the buses are wired. Use the following information to identify specific devices
in your system.
Continuum Series 400/400-CO systems support two internal disk enclosures. The
slots are wired (and labeled) and one SCSI bus supports each enclosure. The slot
order is the same for both enclosures (although the numbering sequence differs
between StorageWorks and Eurologic enclosures). For example, disks in the
rightmost slot of each StorageWorks enclosure use SCSI ID 0 and are logical
addresses 14/0/0.0.0 and 14/0/1.0.0, respectively, while disks in the second
rightmost slot use SCSI ID 4 and are logical addresses 14/0/0.4.0 and
14/0/1.4.0, respectively.
Continuum Series 400/400-CO systems support CD-ROM and tape drives
through the external ports at addresses 14/0/2 and 14/0/3. You can daisy-chain
devices to support more than one CD-ROM or tape drive on a single bus.
lsm3 14/0/3 3 0/3/7/0 none
lsm4 14/0/4 4 0/2/3/0 0/3/3/0
lsm5 14/0/5 5 0/2/3/1 none
