Supported Media 2

Q-EKM supports IBM LTO-4 and IBM LTO 5 media.

Library Firmware

Requirements 2

It is recommended that you upgrade your library to the latest released

version.

Tape Drive Firmware

Requirements 2

It is recommended that you upgrade your tape drive firmware to the

latest version qualified with your library firmware.

Linux System Library

Requirements 2

For Linux, the following libraries must be installed on your Q-EKM

server:

•

glibc, version 2.3 or later

•libstdc++.so5

•libXp.so.6

Using Multiple Q-EKM Servers for Redundancy

Q-EKM is designed to work with tape drives and libraries to allow

redundancy, and thus high availability, so you can have up to two

Q-EKM server servicing the same tape drives and libraries. Moreover,

these Q-EKM servers need not be on the same systems as the tape drives

and libraries. The only requirement is that they be available to the

libraries through TCP/IP connectivity.

This allows you to have two Q-EKM servers that are mirror images of

each other with built-in synchronization as well as a failover in the event

that one Q-EKM server becomes unavailable. When you configure your

library, you can point it to two Q-EKM servers (primary and secondary).

If the primary Q-EKM server becomes unavailable for any reason, the

library will use the secondary Q-EKM server.

In order for the secondary server to be used in a failover situation, its

keystore must be identical to that of the primary server. Keeping the

keystores matched is a manual process (it does not happen

automatically). See Keeping the Keystores Matched

on page 36.
