Changing partition properties and capabilities
You can view and change the partition name, view general properties of the partition, and change the virtualization capabilities by using the Hardware Management Console (HMC).
- Type, version, and IP address of the operating system.
- Machine type and serial number of the system.
- Resource configuration of a logical partition. It indicates whether all the resources that are
necessary to activate the partition are available. When the Resource
Configuration field displays Configured, the partition can be
activated by using the current configuration. When the Resource Configuration
field displays Not Configured and the partition has a last valid
configuration profile, that profile is used to activate the partition. Otherwise, the partition can
be activated by using a profile.Note: When a user, who has access to the partition but does not have access to the partition profile, tries to view the properties of the partition, the user is prompted to Apply Partition Configuration, before proceeding to view and manage the partition.
You can view or change the partition name and keylock position, add a description, and assign group tags.
- Live partition mobility
- Live Partition Mobility is a component of the PowerVM® Enterprise Edition hardware feature that enables moving AIX®, IBM® i, and Linux partitions from one system to another. The mobility process transfers the system environment, including the processor state, memory, attached virtual devices, and connected users.
- With the active partition mobility feature, you can move AIX, IBM i, and Linux partitions that are running, including the operating system and applications, from one system to another. The partition and the applications that run on that migrated partition do not need to be shut down.
- With the inactive partition mobility feature, you can move a powered off AIX, IBM i, or Linux partition from one system to another.
- Suspend/Resume
- Certain models of IBM
Power Systems™ servers support the suspend and resume
feature. On supported models, you can suspend and resume an AIX or Linux partition with its operating system and
applications. Notes:
- You must not suspend the partition when the alt_disk_install command is
running in the VIOS on which the storage is provisioned
for the client.
When a partition is suspended, the state of the partition is saved on persistent storage, and the server resources that were in use by that partition are made available for use by other partitions. Later, you can resume the operation of the suspended partition and the applications.
- On client logical partitions backed by VIOS SSP LUs, HMC supports the suspend and resume feature on the same managed system. However, HMC does not support the suspend and resume feature, if you try to migrate the client to a different managed system, after it is suspended.
Note: The Suspend/Resume feature is excluded from the initial introduction of the POWER8® 8286-41A, 8286-42A, 8286-42A, 8247-21L, and 8247-22L Power Systems™ servers. This feature is fully supported on other models of Power Systems servers with appropriate levels of the management console, firmware, and PowerVM. - You must not suspend the partition when the alt_disk_install command is
running in the VIOS on which the storage is provisioned
for the client.
- Remote restart
- Certain models of IBM Power Systems servers support the remote restart feature. On supported models, you can restart an AIX or Linux partition remotely if the partition supports an attribute that is called an encapsulated state. An encapsulated state partition is a partition in which the configuration information and the persistent data are stored external to the server on persistent storage. A partition that supports remote restart can be restarted remotely. You can recover from a server outage by allowing a partition to start on another server.
- Simplified Remote Restart
- Unlike the remote restart feature, when this capability is enabled, the partition state and
partition configuration data is automatically stored on an HMC that manages the server. Any change to the partition
configuration or profile is automatically synchronized with the data that is stored on the HMC. You can enable or disable the simplified remote restart
capability only when the partition is in an inactive state.Note: When the HMC is at Version 8.6.0, or later, and the firmware is at level FW860, or later, you can enable or disable the simplified version of the remote restart capability when the logical partition is in the Running state. The logical partition must not be in the Suspended, Resuming, Migrating, or Remote Restarting states.
This option is available only when the server is enabled with PowerVM Enterprise Edition and the level of firmware on your server supports the simplified remote restart capability. If a managed system is both Remote Restart Capable and PowerVM Partition Simplified Remote Restart Capable, the page displays the option to manage a simplified remote restart partition only. Also, if the remote restart capability is already enabled for the partition, a message is displayed to indicate that the partition is enabled with the remote restart capability and the capability is disabled when you enable the PowerVM Partition Simplified Remote Restart function.
- You can view the remote restart status for the logical partition, if the partition is simplified remote restart capable. You can also refresh the remote restart data. The partition and profile data, referred to as remote restart data, is stored on the HMC hard drive for partitions that are simplified remote restart capable. For more information on the different states of the remote restart operation, see Remote Restart State.
