User's Manual

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 height drives with full height

drives may require you to execute Restore Factory Defaults to correctly update the

drive element addressing and drive numbering. See “Configure Library:

Save/Restore Configuration” on page 5-57.

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)

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 Height

drives. Library firmware levels higher than B.50 support Path Failover on LTO 6

drives. Library firmware levels higher than 8.xx support Path Failover on LTO 5

drives, as well as LTO 4 Full Height drives. For more information, refer to the Dell

PowerVault TL4000 Failover Configuration Guide, included with the library

documentation.

Enter the Feature Activation key and click Activate. This page will display if you

have entered the feature key correctly.
