connected to a host computer over two loops to two FC ports. In this example, both
ports are on dual-port HBAs.

When you connect your SANnet II 200 FC JBOD array to a host over two loops, the
format
command shows 24 drives, 12 on each loop, because the host sees a device
entry for each path. If the loop switch ID is set to 0, these drives are identified as
ranging from c1t0d0 to c1t11d0 and from c2t0d0 to c2t11d0, as shown in
Table B-4. However there are, of course, still only 12 physical drives in the JBOD
array. These drives are arranged in four columns of three drives each, as shown in
Table B-3.
