Installing a Loopback Connector
Before running the loopback test, you must install a loopback connector on the
HBA port. Note the following about the loopback connector:
„ The loopback connector must be appropriate for the type of FC HBA
connector.
„ Be sure to select the appropriate HBA connector for testing. Each HBA
connector appears in the SANsurfer FC HBA Manager main window HBA
tree as an HBA port.
To install a loopback connector:
1. Disconnect the cable from the appropriate HBA connector.
2. Install the loopback connector on the HBA connector.
Preparing for Normal HBA Operations
When you complete loopback testing, follow these steps to resume normal HBA
operations.
