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).
