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.
