Fibre Channel Fault Isolation Utility; Installing The Utility; Running The Utility - Compaq StorageWorks 4000 - RAID Array Troubleshooting Manual

The Fibre Channel Fault Isolation Utility (FFIU) verifies the integrity of a new or existing FC-
AL installation. When used with troubleshooting flow charts, this utility provides fault detection
and help in locating a failing device on the FC-AL.
Each device on the FC-AL has an Arbitrated Loop Physical Address (ALPA). The ALPA is
allocated dynamicallyit can change with each power-up or as new devices are added to the
loop. The fault isolation utility indicates all devices that are active on the FC-AL. The utility
dynamically updates the screens to show the current ALPA of each component. Additionally, a
Loop Error Histogram is displayed when specific servers or components are highlighted to
further analyze the health of individual components. The utility analyzes Fibre Channel
components including the Host Bus Adapter and the Fibre Channel Tape Controller. The Fibre
Channel Storage Hub 12 is logically transparent to the operations of the FC-AL, but even a
failed Storage Hub 12 can be detected when the Fault Isolation Utility is used in combination
with the Troubleshooting Flow Charts.
