Chapter 11 Example of Fault Isolation 149

Sun Proprietary/Confidential: Internal Use Only

The primary path to Drive F: failed. The alternate path is currently handling all

of the I/O.

3. Check the HBA

Using the HBA utility (Qlogic SANblade in this example), confirm the fault.

4. Isolate the components in the path.

The components in the path are the HBA, the cable, the switch-side GBIC, and the

Sun StorEdge network FC switch itself.

To isolate all components, use a combination of the Storage Automated Diagnostic

Environment and the HBA utility (QLogic SunBlade).

Note – If no HBA utility is present, or if the utilities do not offer diagnostics, a best

guess effort will have to suffice. Storage Automated Diagnostic Environment cannot

test HBAs on Microsoft Windows 2000 hosts at this time.
