Preparing for the Loopback Test
Perform the following steps before running the loopback test:
1. Modify the HBA port settings Connection Options setting (see
section 10.1.2.1).
2. Attach a loopback connector to the Fibre Channel connector on the HBA port
(see section 10.1.2.2).
Skip this step under the following conditions (an echo test will be run instead):
❑ You have a QLA23xx HBA that is connected to the fabric through a
point-to-point connection (F-port).
❑ The HBA is connected to a switch.
❑ Your operating system has one of the driver versions listed in table 10-1.
3. If the HBA port is connected to the fabric through a point-to-point connection
(F-port) and is connected to a switch, make sure the Connection Options
setting is 1—Point-to-Point Only. See section 11.1.1 for information about
viewing and modifying the setting.
