LPAR manager backup files
• Create a backup file of LPAR manager, and keep the backup file safe
before starting the operation, or when performing Operations required
creating backup files on page 6-2.
• Quick recovery can be performed due to creating backup files for LP
configuration even when a failure occurs. We recommend that back up LP
configuration files regularly in case the LP configuration should be restore
to original settings.
Note that, by using the KeepConfig option, you are able to back up an
LPAR manager configuration as of a point in time before device isolation,
even after the device isolation. For details, see
Backing up the LPAR
manager configuration as of a time before device isolation on page 6-3.
• When a hardware failure occurs, isolation or degradation may occur.
Some devices cannot be recognized at the next LP startup time, and some
LP configuration information are deleted or reconfigured when isolation/
degradation occurs in a processor, a memory, or a PCI device. Restore
backup files to return to the original LP configuration information after
hardware exchange when this event occurs. For restrictions of isolation/
degradation, see
Isolation/degradation for CPU, memory, or PCI device on
page 10-14, CPU core degradation on page 10-14.
