Problems with manual license activation
Although authorization codes and encryption license keys use the same format (four groups 
of four hexadecimal digits), you can only use each of them in the appropriate activation 
process. If you use an authorization code when the system expects a license key, the system 
displays an error message, as shown in Figure 12-20.

12.4  Enabling encryption
This section describes the process to create and store system master access key copies, 
also referred to as encryption keys. These keys can be stored on any or both of two key 
providers: USB flash drives or a key server.
Two types of key servers are supported by IBM Spectrum Virtualize:
/SM590000IBM Security Key Lifecycle Manager (SKLM), introduced in IBM Spectrum Virtualize V7.8.
/SM590000Gemalto SafeNet KeySecure, introduced in IBM Spectrum Virtualize V8.2.
IBM Spectrum Virtualize code V8.1 introduced the ability to define up to four encryption key 
servers, which is a preferred configuration because it increases key provider availability. In 
this version, support for simultaneous use of both USB flash drives and key server was 
added.
Organizations that use encryption key management servers might consider parallel use of 
USB flash drives as a backup solution. During normal operation, such drives can be 
disconnected and stored in a secure location. However, during a catastrophic loss of 
encryption servers, the USB drives can still be used to unlock the encrypted storage. 
The key server and USB flash drive characteristics that are described next might help you to 
choose the type of encryption key provider that you want to use.
