Running Loopback and Read/Write Buffer Diagnostic Tests
CAUTION!
Although SANsurfer FC HBA Manager protects against normal operation
interruption and testing disruption, it is your responsibility to ensure that the
diagnostics are run without causing interruptions to other processes and
disruptions to the actual testing process.
The following sections provide information on these diagnostic tests:

Preparing for Diagnostic Testing

Preparation differs for the loopback and read/write buffer tests. In addition, you
can use SANsurfer FC HBA Manager to locate the HBA you want to test.
NOTE:
The loopback test is disabled if you are using inbox drivers with SLES 10.0.
The following sections provide information about how to prepare for diagnostic

Finding the HBA Port You Want to Test

You can find the location of a port by the way the hardware flashes. SANsurfer FC
HBA Manager allows you to activate a flash beacon on a port. This flash beacon
can be toggled on and off. Flash the 2xxx HBA port's LED to locate the HBA port
in your computer.
NOTE:
This feature is not supported on QLA22xx series or older HBAs.
