FRU Tests Available for the A1 or B1 FC Link Segment

The following FRU tests are available for the A1 or B1 FC link segment. All diagnostics are located in /opt/SUNWstade/Diags/bin. Refer to the man pages for more details.

■HBA—qlctest(1M)

■Available only if the Storage Automated Diagnostic Environment is installed on a data host

■Causes HBA to go offline and online during tests

■Switch —switchtest(1M)

■Can be run while the link is still cabled and online (connected to HBA)

■Can be run only from the Storage Service Processor.

■The dev option to switchtest is in the following format:

Port:IP-Address:FCAddress

The FCAddress can be set to 0x0.

Note –If you are testing an A1 or B1 FC link that is connected to an HBA, you must specify a payload of 200 bytes or less. This is a limitation in the HBA application- specific integrated circuit (ASIC).
