Caution: When you change the partition's encryption method to
Application Managed (LME disabled), the data that
was written to the tapes while the partition was
configured for LME enabled can no longer be read,
until you change the partition back to LME enabled.
You will only be disabling for a short time, and then
changing back to LME enabled (just to trigger the key
generation process) so this should have little effect,
unless you forget to turn it back to LME enabled.
5 Wait 3 minutes to allow the changes to complete.
6 Go back to the encryption partition configuration screen and
change the encryption method back to LME enabled (see
Figure 39).
7 Click Apply.
Data encryption keys are generated. The library triggers the SKM
server to generate a set of unique data encryption keys. This takes
15 minutes to an hour or longer, depending on network
performance. The library notifies you when the process is complete.
