NOTE: Any drives that belong to an access group and have hosts mapped to the second
port are considered to be custom mapped. BDPF cannot be enabled on these drives until the
custom mapping is removed.
Advanced Data Path Failover can only be enabled on LTO-6 drives. Basic Data Path Failover
can be enabled on both LTO-5 and LTO-6 drives.
See the HP StoreEver Enterprise Systems Library (ESL) G3 Tape Library User Guide for more
information on modifying partitions.

Verifying data path failover
To verify that basic data path failover is configured, navigate to Monitor→Drives to launch the
Drive Status dialog.
When basic data path failover is enabled for a drive:
• The Link Status for one of the ports is listed as Active.
• The Link Status for the second drive is listed as Passive, meaning that this is the failover port.
• The Data Path Failover column displays Enabled.
When advanced data path failover is enabled for a drive:
• The Link Status for both ports is listed as Active.
• The Data Path Failover column displays Enabled.
