            This Path Failover for the TS3200 Tape Library is designed to provide automatic control path failover to a preconfigured redundant control path in the event that a host adapter or control path drive is lost without aborting the current job in progress. Support is provided under various operating systems such as System p, Linux, Solaris, HP-UX, and Windows for Fibre Channel attachments when the IBM tape device driver is used.

            Data path failover and load balancing supports native Fibre Channel Ultrium 4 Tape Drives in the Tape Library using the IBM tape device driver for System p, Linux, Solaris, and Windows. Data path failover is designed to provide a failover mechanism in the IBM device driver, which is designed to enable you to configure multiple redundant paths in a SAN environment. In the event of a path or component failure, the failover mechanism is designed to automatically provide error recovery to retry the current operation using an alternate, preconfigured path without aborting the current job in progress. This helps allow flexibility in SAN configuration, availability, and management.

            When accessing a tape drive device that has been configured with alternate pathing across multiple host ports, the IBM device driver is designed to automatically select a path through the host bus adapter (HBA) that has the fewest open tape devices, and assign that path to the application. This autonomic self-optimizing capability is called load balancing. The dynamic load balancing support is designed to optimize resources for devices that have physical connections to multiple HBAs in the same machine. The device driver is designed to dynamically track the usage on each HBA as applications open and close devices, and balance the number of applications using each HBA in the machine. This may help optimize HBA resources and improve overall performance. Further, data path failover is designed to provide autonomic self-healing capabilities similar to control path failover, and is designed to failover to an alternate data path in the event of a failure in the primary host-side path. Data path failover and load balancing for Ultrium 4 Tape Drives requires the optional path failover feature.
