To use all the features of Advanced Reporting, you should install the
latest released version of library firmware on your library. For
information on installing library firmware, see
Firmware on page 235.
If an LTO-5 or LTO-6 FC tape drive is the control path for a partition, you
can select another LTO-5 or LTO-6 FC tape drive in that partition for
control path failover. This means that if the control path tape drive fails,
the failover tape drive becomes the control path for the partition. The
failed-over tape drive remains the control path for the partition unless it
fails or the library is restarted. When either of these events occurs, the
library starts over and attempts to use the original control path tape
drive as the control path, and the original failover tape drive for failover.
The control path and failover tape drives are assigned by location in the
library, so even if you replace a tape drive with another LTO-5 or LTO-6
FC tape drive, the library will still fail over or revert to the specified
location.
To configure control path failover, you must have the following setup on
your library:
• Advanced Reporting License. Refer to
Licensable Features
• The control path and failover tape drives must both be LTO-5 or LTO-
6 tape drives, and you must have a minimum of two drives in a
single partition.
• The control path and failover tape drives must have their topology
configured as Point to Point. Refer to
Parameters on page 64.
