HP StoreEver MSL6480 Tape Library - Manual (Page 29)

Figure 8 Status of the Partitions Configuration to verify basic control path failover
After verifying library connectivity using each of the library control paths, the library control path
can be moved back to the original drive if needed by power cycling the alternate control path
drive.
Configuring data path failover
Basic and advanced data path failover can be used with the drive ports configured in loop mode
or fabric mode. For best results and compatibility with basic control path failover, HP recommends
that the drive ports be configured in fabric mode and connected to an FC switch.
Enabling data path failover
Data path failover is configured with the Expert Partition Wizard. From the Configuration area,
click Expert Wizard in the Partitions menu to start the wizard. Select the type of data path failover
for each tape drive in the partition from the Select Data Path Failover Settings screen.
For example, Figure 9 (page 29) shows advanced data path failover enabled for drives 1 and 2.
In this case, Advanced DPF was pre-set by the wizard because Advanced CPF is configured for
the partition. Because a partition cannot use a mixture of basic and advanced failover, the wizard
will not allow Basic DPF to be selected in this case.
