Chapter 3. Installing the Encryption Key Manager and

Keystores

The Encryption Key Manager is shipped with the IBM Java Virtual Machine

installation, and requires the IBM Software Developer Kit for Linux, and the IBM

Runtime Environment for Windows (see “Hardware and Software Requirements”

on page 2-2). Follow the procedure appropriate for your operating system:

v

“Installing the Encryption Key Manager on Linux”

v

“Installing the Encryption Key Manager on Windows” on page 3-2

If you are uncertain whether you have the latest version of Encryption Key

Manager, “Downloading the Latest Version Key Manager ISO Image” explains how

to learn if a newer version is available. It is a good idea to get the latest version of

Encryption Key Manager, which may not be in your Java installation. Visit

http://support.dell.com

for more information.

IMPORTANT Encryption Key Manager HOST SERVER CONFIGURATION

INFORMATION: It is recommended that machines hosting the Dell

Encryption Key Manager program use ECC memory in order to minimize

the risk of data loss. The Encryption Key Manager performs the function of

requesting the generation of encryption keys and passing those keys to the

LTO 4 and LTO 5 tape drives. The key material, in wrapped (encrypted

form) resides in system memory during processing by the Encryption Key

Manager. Note that the key material must be transferred without error to the

appropriate tape drive so that data written on a cartridge may be recovered

(decrypted). If for some reason key material is corrupted due to a bit error in

system memory, and that key material is used to write data to a cartridge,

then the data written to that cartridge will not be recoverable (i.e. decrypted

at a later date). There are safeguards in place to make sure that such data

errors do not occur. However, if the machine hosting the Encryption Key

Manager is not using Error Correction Code (ECC) memory there remains a

possibility that the key material may become corrupted while in system

memory and the corruption could then cause data loss. The chance of this

occurrence is small, but it is always recommended that machines hosting

critical applications (like the Encryption Key Manager) use ECC memory.

Installing the Encryption Key Manager on Linux

Installing the Encryption Key Manager on Linux From the CD

1.

Insert the Dell Encryption Key Manager CD and enter

Install_Linux

from the

CD root directory.

The installation copies all contents (documentation, GUI files, and configuration

property files) appropriate to your operating system from the CD to your hard

drive. During installation, your system is checked for the correct IBM Java

Runtime Environment. If not found, it is automatically installed.

When installation is complete, the Graphical User Interface (GUI) is started.
