Control Path failover support for tape libraries

Note: The library control path failover feature code must be installed before enabling the path failover support in the Atape device driver. Refer to Automatic failover for what feature codes might be required for your machine type.

The Atape device driver path failover support configures multiple physical control paths to the same logical library within the device driver. It also provides automatic failover to an alternate control path when a permanent error occurs on one path. This support is transparent to the running application.
