SM Loop Test
NOTE:
QLogic recommends to change this parameter before starting loop
test. If the parameter is changed after starting loop test, packets will
have to be injected with fm_cmd smLooptestInjectPackets
option.
• Set the minimum number of loops in which to include each ISL
/opt/qlogic_fm/bin/fm_cmd smLooptestMinISLRedundancy
Applicable only when running in Fast Mode
Default is 4
Packet Injection Options
• Packets are injected if the loop test is started normally and a number of
packets has been specified as an argument to the command:
/opt/qlogic_fm/bin/fm_cmd smLooptestStart 4
• Four Packets are injected by default if loop test is started in Fast Mode:
/opt/qlogic_fm/bin/fm_cmd smLooptestFastModeStart
In fast mode, once loop test is started packets are injected only once. They
are not injected at every sweep.
• Packets can be injected once the loop test has been started:
/opt/qlogic_fm/bin/fm_cmd smLooptestInjectPackets numPkts
• Packets can be injected to specific switch node:
/opt/qlogic_fm/bin/fm_cmd smLooptestInjectAtNode
SwNodeIndex
• Packets can be injected on each sweep:
/opt/qlogic_fm/bin/fm_cmd smLooptestInjectEachSweep
The fm_cmd smLooptestInjectEachSweep parameter can be used in
both fast and default mode loop test case to control whether each sweep will
inject a packet or not. In fast mode, the default is not to inject on each
sweep, but it can be changed to inject on each sweep after the loop test is
started. In default mode, this parameter can be changed either before or
after loop test is started to enable packet injection on each sweep.
