Chapter 11 Example of Fault Isolation 153
Sun Proprietary/Confidential: Internal Use Only
The first run failed, indicating a problem with either the GBIC or with the Sun
StorEdge network FC switch.
To further isolate the problem, a new GBIC was inserted into the port, the loopback
connector was re-inserted, and the same test was run a second time.
FIGURE 11-8 Successful Switch Test Results
On this pass, the test was successful. This indicates that the problem was most likely
the switch-side GBIC, which was replaced.
6. Recover the problem with the GBIC or the switch.
a. Recable the link between the HBA and switch.
b. Use the Sun StorEdge T3+ Array Failover Driver GUI for the Sun StorEdge 3900
series system, or the CLI for the 6900 series, to recover the multipathing.
