24 Dell Encryption Key Manager and Library Managed Encryption
My PowerVault TL2000/TL4000 posts an LME Failure when I change
the configuration from Library-Managed Encryption to
Application-Managed Encryption
This is a false failure. The IP address field is cleared when the configuration
is changed. This field is required for library-managed encryption and the
failure is generated when it is cleared. This field is not required for
application-managed encryption.
My PowerVault TL2000/TL4000 is configured for library-managed
encryption and my RMU shows an error condition with no
associated text
Most likely an LME failure has occurred. The failure message is not posted
on the RMU. It can be viewed through the RMU by navigating to the warning
log in the unit. To clear the error, it must be acknowledged in the OCP.
This issue was fixed in the 7.40 version of the library firmware (version A07
on support.dell.com).
When I attempt to add a drive manually using adddrive in the CLI,
it asks for a 12-digit drive serial number. The drive serial number
is only 10 digits
Two leading zeroes must be added to the 10 digit drive serial number to make
up the 12 digit serial number entered when using adddrive.
Example: Drive serial number is 1234567891. Use 001234567891 for drive serial
number in adddrive.
How is my backup application affected when I configure the library
for library-managed encryption?
Setting changes are made in the drive after library-managed encryption is
enabled on the library. The backup application services must be stopped and
restarted after library-managed encryption is enabled to ensure the backup
application recognizes the encryption setting in the drive.
The tape backup application does not show encryption as enabled if
library-managed encryption is used. The tape backup application only shows
encryption as enabled if the application is providing the keys to the drive
(application-managed encryption).
