Chapter 7: Encryption Key Management
Configuring Scalar Key Manager (SKM) on the Library
Quantum Scalar i40 and Scalar i80 User’s Guide 185
Table 7 Encryption Methods
4 If you want to enable Key Reuse for a partition, select the Key Reuse
check box. See
About Key Reuse on page 178.
5 Click Apply.
SKM: When you set the Encryption Method to LME enabled on a
partition for the first time, the library automatically triggers each
SKM server to generate a set of unique data encryption keys. This
may take 15 minutes to an hour or longer, depending on network
performance. The library notifies you when the process is complete.
Wait for the process to complete before resuming library
operations.

Description
Library Managed
Encryption (LME)
- enabled
For use with EKM. Enables encryption support
via a connected EKM key server for all encryption-
capable tape drives and media assigned to the
partition.
Library Managed
Encryption -
disabled
Not for use with EKM. Allows an external
backup application to provide encryption support
to all encryption-capable tape drives and media
within the partition. The library will NOT
communicate with the EKM key server on this
partition.
This is the default setting if you have encryption-
capable tape drives in the partition. This option
should remain selected unless you are
connecting the library to an external EKM key
server.
Note: If you want an external application to
manage encryption, you must specifically
configure the application to do so. The library will
not participate in performing this type of
encryption.
Unsupported Means that one or more tape drives in the
partition do not support encryption.
If Unsupported is shown, it will be greyed out
and you will not be able to change the setting.
