Automatic failover to an alternate physical path when a permanent error occurs on one path. 2. Dynamic load balancing for tape devices using multiple Host Bus Adapters (HBA). Path Failover is supported on certain tape products with the latest IBM device drivers available on the following ftp download site: ftp://ftp.software.ibm.com/storage/devdrvr Some devices require a path failover feature code to be installed prior to enabling the path failover support in the device driver. Refer to Table 3 on page 16 for a list of supported devices and what path failover feature code may be required for your machine type. Automatic Failover The automatic failover support provides error recovery on an alternate path when a permanent error occurs on the primary path. This is transparent to the running application. There are two types of Path Failover, Data Path Failover (DPF) and Control Path Failover (CPF). They are closely related however the difference is that DPF is an automatic failover support for the transfer of data, which provides error 12 IBM Tape Device Drivers Installation and User's Guide
