94 IBM Power System S822 Technical Overview and Introduction
򐂰 IBM Systems Director agent and several preinstalled IBM Tivoli® agents, such as the
following examples:
– Tivoli Identity Manager, to allow easy integration into an existing Tivoli Systems
Management infrastructure
– Tivoli Application Dependency Discovery Manager (ADDM), which creates and
automatically maintains application infrastructure maps including dependencies,
change-histories, and deep configuration values
򐂰 vSCSI enterprise reliability, availability, serviceability (eRAS).
򐂰 Additional CLI statistics in svmon, vmstat, fcstat, and topas.
򐂰 VIOS Performance Advisor tool provides advisory reports based on key performance
metrics for various partition resources collected from the VIOS environment
򐂰 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.
For more information about the Virtual I/O Server and its implementation, see: IBM PowerVM

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.
Live 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 that run 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.
The PowerVM Server Evacuation function allows to perform a server evacuation operation.
This process is used to move all migration capable logical partitions from one system to
another at a time. Any upgrade or maintenance operations can be performed after all the
partitions are migrated and the source system is powered off.
