Basic Data Path Failover (BDPF): Basic Data Path Failover is a feature
provided as part of the Storage Networking license and applies to HP
LTO-5 and later Fibre Channel tape drives only. It provides an alternate
data path when a preferred data path fails. If you previously installed a
Storage Networking license, you can use this feature once you upgrade
library firmware to the appropriate version. Verify firmware version
Scalar i6000 Release Notes
requirements in the
The HP LTO-5 and later Fibre Channel tape drives have two Fibre Channel
ports. If you enable Data Path Failover on the tape drive, one port is
used as the "active port" for data transmission, and the other port
stands by for use if the active port fails. If the tape drive loses its Fibre
Channel link with the active port, it will automatically "fail over" and use
the standby port to continue drive operations.
