Fibre Channel ID Assignment
Each FC drive slot has a unique ID assigned to it.
The IDs are assigned by a combination of slot number and
enclosure ID. The slot numbers are pre-assigned, as shown in

between 0 and 9, using the ID switch on the ES module, shown in

When you power-on the enclosure, the ES module and LIO module
read the ID switch setting and set the enclosure ID.
If you change the enclosure ID, you must power cycle the enclosure
before it will read the change.
