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 128.
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 information on minimum firmware levels for path failover, see
“Minimum firmware levels for common library features” on page v. 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.
Note: Follow the instructions in the Dell PowerVault TL4000 Failover Configuration Guide to configure your
environment for failover.

Encryption requires a license key. Contact your TSR (technical sales representative) to purchase this
feature.
