Two-Server Configuration 2

The recommended two-server configuration allows the library to

automatically fail over to the secondary Q-EKM server should the

primary Q-EKM server be inaccessible for any reason.

In an environment with two Q-EKM servers, such as those shown in

Figure 3

, the library will automatically fail over to the secondary Q-EKM

server should the primary go down. In such a configuration it is essential

that the servers are synchronized and that the two keystores match.

Once synchronization is configured, updates to the configuration files of

the primary Q-EKM server are automatically duplicated on the secondary

Q-EKM server (see Synchronizing Primary and Secondary Q-EKM

Servers on page 33). However, the keystore file is not automatically

updated. Any change to the keystore on the primary server (such as

Note: When different Q-EKM servers are used to handle requests

from the same set of tape drives, the information in the

associated keystores MUST be identical. This is required so

that regardless of which Q-EKM server is contacted, the

necessary information is available for the Q-EKM server to

support requests from the tape drives.
