The disks shown in the previous sample ioscan -fn are the ST318451FC (used in
the A6191A disk module) and the ST336704FC (used in the A6192A disk
module). The full descriptions of the supported disk modules are:
■ ST336605FC 36 Gbyte 10K rpm disk FC disk module (A6192A)
ST336704FC
■ ST373405FC 73 Gbyte 10K rpm disk FC disk module (A6194A)
■ ST318451FC 18 Gbyte 15K rpm disk FC disk module (A6191A)
ST318452FC
■ ST336752FC 36 Gbyte 15K rpm disk FC disk module (A6193A)
Interpreting the Hardware Path
The elements of the Fibre Channel hardware path are interpreted as follows:
The loop ID, broken out in upper and lower bits in the example above, is 46. To
derive the loop ID from the Bus and Target values of the hardware path:
1 Convert the Bus and Target fields (the upper and lower bits of the loop ID) to
binary:
8/12.8.0.255.2.14.0
Bus Converter
Adapter
Protocol Type (8 = mass storage)
Port (255 = the target connected directly to the FC)
Bus (Upper 4 bits of the loop ID)
Target (Lower 4 bits of the loop ID)
Area (0 = point-to-point or private loop)
LUN (Logical Unit Number of disk)
8/12.8.0.255.2.14.0
0 0 1 0 (Upper 4 bits of the loop ID)
1 1 1 0 (Lower 4 bits of the loop ID)
