Saving configuration data on a logical partition
Logical partition configuration data is automatically maintained for the life of the physical system. Each logical partition load source contains the configuration data.
Only disaster recovery to a different physical system requires that you rebuild the configuration from the beginning. You should print your system configuration when you make changes to your logical partition configuration. This printout will help you as you rebuild the configuration.
During a save operation, the configuration data for the logical partition is not saved to the media volume. This enables data to be restored to a system even if it has logical partitions. However, you can work with the configuration data for logical partitions as needed for recovery purposes.
Attention: Logical
partitions that you keep powered off for extended periods should be restarted at
least once after any change to the logical partition configuration.
This enables the system to update the changes on that logical partition's
load source.
Attention: If you are using the Hardware
Management Console (HMC), you must back up the HMC in addition to
saving the individual logical partitions.
Attention: If you are using Integrated
Virtualization Manager and want to back up the partition configuration
data, see the PowerVM® Editions topic
collection in the IBM® Power Systems Hardware
Information Center.
