Control Path failover support for tape libraries
Note: The library control path failover feature code must be installed
before control path failover support is enabled in the Linux® lin_tape device
driver. Refer toAutomatic failover to
determine which feature code is required for your machine type.
The Linux lin_tape device driver control path failover support configures multiple physical control paths to the same logical library within the device driver. It also provides automatic failover to an alternative control path when a permanent error occurs on one path. This support is transparent to the running application.
