Communication on the loop does not occur in a simple, orderly sequence. The
relationship between the physical location of a disk and the order in which it is
accessed can be complex.
The order in which disk are accessed is important when analyzing port error
rate metrics. Knowing the order in which communication on the loop occurs
can facilitate isolating the problem. For example, if a disk is experiencing a
high error rate on one of its ports, knowing which disk is the predecessor in the
loop can help identify which disk or path may be at fault.
