
When using D_Port in a boot from SAN configuration, the configuration must
have redundant paths to the boot LUN and only one of the redundant adapter
ports should be set to D_Port.

Syntax
DPortTest
Parameters
Considerations When Using D_Port

Because it is not possible to detect if a Brocade switch can support D_Port
functionality, a test failure occurs if the DPortTest command is run with a
switch that does not support D_Port testing.

Typing while the D_Port tests are running terminates the tests and the
completed results are displayed.

If the Overall Test Result is "FAILED", you must either re-run the tests
successfully, or reset the adapter port to bring up the link.

If a test phase fails, the D_Port diagnostics are automatically stopped. As a
result, test phases that would have occurred after the failure are not displayed.

When there is more than one error in a single test phase, multiple lines are
displayed showing each error.
