Configuring FC Host Port Failover

This topic describes how to configure the host port failover feature. For an overview of host port failover, see About FC Host Port Failover.

NOTE: This operation should not be performed concurrently by multiple administrators logged in from different locations. You can access the appropriate screens, but you cannot apply changes while another administrator is performing the same operation.

You need administrator privileges to configure host port failover.

1. From the Setup menu, select FC I/O Blades > Host Port Failover.

   The Setup - Host Port Failover screen appears. The screen displays all the FC I/O blades found in the library. The screen lists the location, World Wide Node Name (WWNN), and status of each blade.

2. Select an FC I/O blade and click Next.

   The Setup - Blade Port Failover screen appears.

   NOTE: To enable host port failover, you must configure target ports 1 and 2 on the FC I/O blade as point-to-point connections (Setup > FC I/O Blades > Port Configuration). FC I/O blade target ports 1 and 2 must be attached to the same SAN fabric to provide host access. See Configuring FC I/O Blade Ports.

3. Do one of the following:
   • To enable host port failover, select Enable FC Host Port Failover. Continue with step 4.

   • NOTE: An error message appears if channel zoning has been configured to restrict access between target ports 1 and 2 and initiator ports 3 to 6 on the FC I/O blade. You must configure channel zoning so all target ports have access to all initiator ports. For more information, see Configuring Channel Zoning.

   • To disable host port failover, clear Enable FC Host Port Failover. Continue with step 5.

   NOTE: When FC Host Port Failover is enabled for the first time, the Active Port will be configured to Port 1. When the Active Port is changed, intervention is required to make both ports available for failover, see Repairing and Enabling a Failed Port

4. Click Apply. The Progress Window displays. The Progress Window contains information on the action, elapsed time, and status of the requested operation.

1. • If Success displays in the Progress Window, the operation was successful. Click Close to close the Progress Window.
   • If Failure displays in the Progress Window, the operation was not successful. Follow the instructions listed in the Progress Window to resolve any issues that occurred during the operation.
6. Save the library configuration.

   For instructions on how to save the library configuration, see Saving the Configuration.
