-lb

(Perform Loopback Test)

CAUTION!

Before doing a loopback test, ensure that the HBA does not have any outstanding I/O operations.

To run a loopback test, enter the -lbcommand as follows:

-lb <hba_port_inst> [-STOP] [-EXTLB] [-CNT <Test Count>]

Where:

hba_port_inst = The HBA port where you do the loopback test. –STOP= The loopback test stops if a failure occurs.

–EXTLB= Runs an external loopback test. By default, runs an internal loopback test.

-CNT= Used with Test Count to say how many loopback tests to run. Default is 1.

Test Count = The number of loopback tests to run. One is the default. To run more than one test, enter a number between 2–(2^31).

For information on the interactive version of this command, see “Perform Loopback Test (CLI Option -lb)” on page 4-31.

-lc

(Configure Link Configuration)

To configure the link settings, enter the -lccommand as follows:

-lc <hba_port_inst>

The optional parameters are auto-negotiate [-AUTONEG], link speed [-LNKSPD], and flow control [-FLOW]. With auto-negotiate on, no entries should be provided for link speed. For a copper connection and auto-negotiate off, a link speed of 100 or 10 must be provided. For a fiber connection, the link speed is always 1000 Mbs. The optional parameter [-FLOW]will turn on or off flow control.

-lcd

(Display Configured Link Configuration)

To display the configured link settings, enter the -lcd command. Note that because a system reset is required for changes in link configuration to take effect, the settings shown here may be different than the operating link configuration.
