TS3100 Tape Library and TS3200 Tape Library Setup, Operator, and Service Guide
Note: When reducing the number of drives in your library, update the Logical
Library configuration. This will remove the Attention LED on the front
panel and the exclamation mark on the Home screen indicating that a drive
is missing.
Updating the Logical Library configuration will also update the drive element
addressing and drive numbering. Replacing LTO half high drives with full high
drives may require you to execute Restore Factory Defaults to correctly update the
drive element addressing and drive numbering. See "Configure Library:
Save/Restore" on page 5-68.
Configure Library: Path Failover
This page allows the user to enter the Path Failover feature activation key
(Supported on 4U library only for library firmware levels at or below 8.xx.
Supported on both the 2U and 4U libraries with library firmware levels above 8.xx)
Path Failover is a combination of two previous features: Control Path Failover (key
entered at the library user interface) and Data Path Failover (key entered at the
device driver interface). A single activation key entered at the library user interface
now activates both features unless the LTO-3 drive firmware level is equal to or
lower than 73P5 and/or the library firmware is equal to or lower than 1.95. For
either or both of these two cases, the device driver interface Data Path Failover key
activation will still be required. For library firmware levels below 8.xx the Path
Failover feature is available for select LTO 4 tape drives, and Path Failover is not
supported for Half High drives. Library firmware levels higher than B.50 support
Path Failover on LTO 6 Full High and Half High drives. Library firmware levels
higher than 8.xx support Path Failover on LTO 5 Full High and Half High drives,
as well as LTO 4 Full High and Half High drives.
Enter the Feature Activation key and click Activate. This page will display if you
have entered the feature key correctly.
