HP StorageWorks 2/64 - Core Switch Command Reference Manual page 133

At each pass, a different data type is used to create the frame from a palette of seven types meaning that
if a pass of seven is requested, seven different frames are used in the test. If eight passes, the first seven
frames are unique, and the eighth is the same as the first. The data palette of seven are:
CSPAT:
BYTE_LFSR:
CHALF_SQ:
QUAD_NOT:
CQTR_SQ:
CRPAT:
RANDOM:

ports that are cable loopbacked to ports in the same switch are tested. Ports connected outside of the
switch are ignored.
To run the

this is the default) or two ports (lb_mode = 0) cable loopbacked to each other. If this criteria is not met,
one of the following message is displayed:
Need at least 1 port(s) connected to run this test.
Need at least 2 port(s) cross-connected to run this test.
In offline mode (when the switch is disabled prior to executing the
are assumed to be cable loopbacked to different ports in the same switch. If one or more ports are not
connected, the test aborts.
NOTE: All ports must be connected using loopback plugs or loopback cables for this test to run correctly
in offline mode.
The test determines which port is connected to which port transmitting frames. If any ports are not properly
connected (improperly seated SFPs or cables, bad SFPs or cables, or improper connection or improper
connection of SWL to LWL), the following message is displayed:
One or more ports is not active, please double check
fibre channel connections on all ports.
Since this test includes the media and the fiber cable in its test path, its results combined with the results of

faulty. It is also possible to use loopback modes 3 and 5 to further isolate failures; see -lb_mode, below.

spinSilk
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.
Specify the loopback mode for the test. By default,
1 port loopback. Valid values are:
0 Cable loopback
1 Port loopback (loopback plugs)
2 External (SERDES) loopback
3 Silkscreen loopback
5 Internal (parallel) loopback
