HP StorageWorks MSA 2/8 - SAN Switch Reference Manual page 167

Since this test includes the media and the fiber cable in its test path, its results
combined with the results of portloopbacktest and spinsilk can be used to
determine which components of the switch are faulty. It is also possible to use
various loopback modes 3 and 5 to further isolate failures, see to -lb_mode below.
Operands
This command has the following operands:
passnum
(V3.1.x only)
singleportalso
(V3.1.x only)
--slot number
(V4.1.x only)
-nframes count
(V4.1.x only)
Fabric OS Version 3.1.x/4.1.x Reference Guide
Specify the number of frames to send. The test will
progress until the specified number of frames has
been transmitted on each port. The default value is
10, so the number of frames sent will be at least 10.
Specify 1 to enable singleportalso mode. This enables
the command to test ports that are cable loopbacked
(port M is connected to port M) in addition to the
cross connection ports (port M is connected to port
N).
Specify the slot number in a StorageWorks Core
switch. The slot number must be followed by a slash
( / ) and the port number.
The StorageWorks Core switch has a total of 10 slots
counted from 1 to 10. Slot number 5 and 6 are
control processor cards, and slot 1 through 4, and 7
through 10, are switch cards. On each switch card,
there are 16 ports counted from the bottom, 0 to 15.
A particular port must be represented by both slot
number (1 through 4, or 7 through 10), and port
number (0 through 15).
This operand is not required for switches that do not
have slots.
Specify the number of frames to send. The test will
progress until the specified number of frames has
been transmitted on each port. The default value is
10, so the number of frames sent will be at least 10.
