Powervm Live Partition Mobility - IBM Power 720 Overview

Additional CLI statistics in svmon, vmstat, fcstat, and topas
Monitoring solutions to help manage and monitor the Virtual I/O Server and shared
resources
Commands and views provide additional metrics for memory, paging, processes, Fibre
Channel HBA statistics, and virtualization.

3.4.5 PowerVM Live Partition Mobility

PowerVM Live Partition Mobility allows you to move a running logical partition, including its
operating system and running applications, from one system to another without any shutdown
or without disrupting the operation of that logical partition. Inactive partition mobility allows
you to move a powered-off logical partition from one system to another.
Partition mobility provides systems management flexibility and improves system availability:
Avoid planned outages for hardware or firmware maintenance by moving logical partitions
to another server and then performing the maintenance. Live Partition Mobility can help
lead to zero downtime maintenance because you can use it to work around scheduled
maintenance activities.
Avoid downtime for a server upgrade by moving logical partitions to another server and
then performing the upgrade. This approach allows your users to continue their work
without disruption.
Avoid unplanned downtime. With preventive failure management, if a server indicates a
potential failure, you can move its logical partitions to another server before the failure
occurs. Partition mobility can help avoid unplanned downtime.
Take advantage of server optimization:
– Consolidation: You can consolidate workloads running on several small, under-used
servers onto a single large server.
– Deconsolidation: You can move workloads from server to server to optimize resource
use and workload performance within your computing environment. With active
partition mobility, you can manage workloads with minimal downtime.
Hardware and operating system requirements for Live Partition Mobility
PowerVM Live Partition Mobility requires systems with POWER6 or newer processors
running, PowerVM Enterprise Edition and is supported for partitions running the following
levels of operating systems:
AIX 5.3 TL7 or later
IBM i 7.1 TR4 or later
SUSE Linux Enterprise Server 10 Service Pack 4 or later
Red Hat Enterprise Linux version 5 Update 1 or later
The Virtual I/O Server partition itself cannot be migrated.
Requirement for IBM i: Live Partition Mobility on IBM i is not supported on POWER6 or
POWER6+-based servers.
