It is recommended that you set the EKM server with a static IP address

to avoid changes in the IP address. With the EKM server IP address set to

Dynamic using a DHCP server, there is the possibility of the E KM server

IP address being changed by the DHCP server. When the IP address changes,

the library has no way to access the EKM server. All subsequent encrypted

backup jobs fail if there is no available EKM server to provide the required keys.

If the library firmware supports key path diagnostics, the diagnostics should be

run to validate the EKM connectivity prior to starting normally scheduled

backups. This ensures that scheduled backup jobs complete successfully.

If the library firmware does not support key path diagnostics, the firmware can

be updated to the most recent version so that key path diagnostics can be used.

Test backups can also be used to validate the EKM connectivity.

When using new media, the user must ensure that the tape backup software

application recognizes the media as available for backup and is in a valid state

prior to encrypting data on the media.This ensures that scheduled backup jobs

complete successfully.

To avoid data loss, key path diagnostics should be run on the library to

validate that the EKM server or servers are still running. EKM can be

configured as a Microsoft Windows service so that it automatically restarts if the

system is rebooted. To configure EKM as a Windows service, see "How do I

configure EKM to run as a Windows service in a 32-bit environment?" on page 13.

Media portability rules with library-managed encryption are consistent with

media portability rules between different types of backup software. Currently

media encrypted through library-managed encryption cannot be restored

through a standalone drive due to lack of support for standalone drives in EKM.

Media encrypted in one Dell PowerVault tape library can be restored through

another PowerVault tape library as long as the key store associated with the

original library can be accessed by the second library.
