Forcing Data Path Failover

You can manually switch the active Fibre Channel port on a DPF-enabled tape drive by forcing a failover. You might want to force a failover to check that the non-enabled port still works, or to switch back to using Port 1 once the issue that originally caused it to fail over is fixed.

To force a failover:

1. From the Tools menu, click Drive Operations.
   
   The Tools - Drive Operations screen displays.
2. Select Force Data Path Failover and click Next.
   
   The Force Data Path Failover page displays. All of the tape drives that have data path failover enabled are listed. The port currently being used as the data path is listed in the Active Port column. The Active Port column will state “No Link” if neither port is connected.
3. Select the radio button of the tape drive on which you want to force the failover. The tape drive must be in the “ready” state in order to be selected.
4. Click Apply.
   
   The new active port displays in the Active Port column.

   NOTE: If the new active port does not display, refresh the page in the browser. .

   NOTE: The library will issue a RAS ticket if the forced failover attempt fails. It will not issue a RAS ticket if the forced failover succeeds.
