## LTO Lib Managed Encryption (FC5900) 

TS4300 tape libraries support data encryption on the base drive with LTO-8, 7, 6, 5, and 4 media meeting LTO Generation 8 and 7 media specifications and AME. LME is supported by the LTO LME feature number 5900. IBM Security Key Lifecycle Manager (SKLM) V1 or later is required with this feature. 

## Path failover (FC1682) 

The path failover feature ensures the use of a redundant communication path when the primary path fails. Two types of path failover capabilities exist: Control Path Failover (CPF) and Data Path Failover (DPF). 

## Control Path Failover 

A control path  is a logical path into the library through which a server sends standard SCSI medium changer commands to control the logical library. Other control paths reduce the possibility that failure in one control path causes the entire library to be unavailable. Use of the Control Path Failover feature further reduces that possibility. 

Control path failover is configured on the host device driver. The device driver is controlling failover for the host. For more information and about how to configure this function, see IBM Tape Device Drivers Installation and User’s Guide , GC27-2130. 

## Data Path Failover 

Data Path Failover provides a failover mechanism in the IBM device driver with which you can configure multiple redundant paths in a SAN environment. If a path or component failure occurs, the failover mechanism automatically provides error recovery to try the current operation again by using an alternative, preconfigured path without stopping the current job in progress. This feature provides flexibility in SAN configuration, availability, and management. 

Data path failover is configured on the host device driver. The device driver is controlling failover for the host. For more information and about how to configure this function, see IBM Tape Device Drivers Installation and User’s Guide , GC27-2130. 

## 12.7 Library management 

The library includes the following interfaces for management: 

GLYPH<SM590000> Operator Control Panel (OCP) for local management 

GLYPH<SM590000> Web UI for remote management through the network 

The operator panel is on the front of the base library module. With the Operator Control Panel, operators can work locally on the library by using the touch panel. With the web UI, you can view and perform several library functions from remote sites. 

## 12.7.1 Operator Control Panel 

The Operator Control Panel is on the front panel of the base module with its associated buttons to the right side. To access the menus, you must first log in by using the panel and buttons. The first display that is shown is the main panel, as shown in Figure 12-11 on page 327. 

The main panel provides four menu options:
