LTO Lib Managed Encryption (FC5900) Path failover (FC1682) Control Path Failover Data Path Failover 12.7 Library management 12.7.1 Operator Control Panel 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. 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). 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 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. The library includes the following interfaces for management: 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.  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: 326  IBM Tape Library Guide for Open Systems GLYPH<SM590000> Operator Control Panel (OCP) for local management GLYPH<SM590000> Web UI for remote management through the network
