8.3.1

FC-AL Loop Problem Indicators

The following symptoms indicate possible FC-AL loop problems:

1. The first indication observed by a customer might be performance degradation in

the suspect Sun StorEdge T3 array. See Section 8.3.2, “Checking Performance
Against Baseline Data” on page 8-12 for more detail.

2. A second indication might be StorTools message monitoring from a host that is

receiving remote array

syslog

messages. StorTools monitoring can be configured

to look for particular message classes in the log file that the array entries are
written to. The program looks through this log file at a customer- determined
