card itself, must be assigned a unique fibre ID number. A Fibre channel can

connect up to 128(0 to 127) devices. The RAID subsystem is as a large Fibre

device. We should assign an LUN base from a list of Fibre LUN Base.

Fibre LUN: Each Fibre LUN base can support up to 8 LUNs. Most Fibre

Channel host adapter treats each LUN like a Fibre disk.

3.7.3.1.8 Tag Queuing

The Enabled option is useful for enhancing overall system performance under

multi-tasking operating systems. The Command Tag (Drive Channel) function

function should normally remain enabled. Disable this function only when using

older SAS drives that do not support command tag queuing.
