Enabling D_Port testing with a QLogic HBA
This task illustrates how to enable D_Port testing with a QLogic HBA.
D_Port testing is supported on QLogic 16G and 32G cards. For the latest firmware/driver and product-specific details, go to
www.qlogic.com. If the latest firmware/driver supporting D_Port testing is installed in the server, nothing further needs to be done on the
server side.
NOTE
The QLogic cards support only electrical and optical loopback tests. They do not support link traffic tests.
1. On the Brocade switch, convert the port from an F_Port to a D_Port, disabling the specified F_Port by entering the portDisable
port_ID command, as in the following example.
switch:admin> portdisable 1/1
2. Enter the portCfgDport --enable port_ID command.
switch:admin> portcfgdpdort --enable 1/1
3. Enable the port by using the portEnable port_ID command.
switch:admin> portenable 1/1
The D_Port test begins automatically.
