Marvell recommends running diagnostics port tests on multipath configured boot
from SAN (BFS)/Fabric Assigned Boot LUN (FABootLUN). Using single path
BFS/FABootLUN may cause issues with OS stability in true BFS environments.
Not all SFP vendors support the optical output (OWRAP) and electrical output
(EWRAP) capability that is required for a D_Port configured on the switch or
Diagnostics Port configured on the Marvell QLogic Fibre Channel Adapter.
Brocade features are not supported on all mezzanine cards.
When a switch port is enabled as a D_Port, the Marvell QLogic 2600 or 2700
Series Adapter automatically runs the basic diagnostic test at both ends of the
link. The Brocade switch then runs the following additional tests:
Electric loopback test
Optical loopback test
Measure link distance test
Link traffic test
Example output of a Dport test result is as follows:
Using config file: M:\qaucli\qaucli.cfg
Installation directory: M:\qaucli
Working dir: M:\qaucli
