Dec 2011
The following updates have been made to the content:
- On the VIOS Version 2.2.1.3, or later, you can create a cluster that consists of up to four VIOS partitions connected to the shared storage pool and that has access to distributed storage. The following information is updated for shared storage pools:
Oct 2011
The following updates have been made to the content:
- With HMC Version
7.7.4, or later, and POWER7 processor-based
servers with firmware at level 7.4, or later, you can enable Virtual
Trusted Platform Module (VTPM) on an AIX logical
partition. A logical partition that is enabled for VTPM has the Trusted
Boot capability. Trusted Boot is an offering that is supported on
the Power® Security and Compliance
(PowerSC) Standard Edition.
The following information is new or updated for logical partitions
that have the Trusted Boot capability:
- Trusted Boot
- Configuration requirements and restrictions for suspending a logical partition
- Verifying that the server supports Virtual Trusted Platform Module
- Enabling and disabling a Virtual Trusted Platform Module on a logical partition
- Creating a logical partition with Virtual Trusted Platform capability
- Viewing the Virtual Trusted Platform Module settings
- The HMC Version 7.7.4, or later, provides the capability to provision shared storage pools. The following information is new or updated for shared storage pools:
May 2011
The following updates have been made to the content:
- On POWER7 processor-based servers, with firmware at level 7.3, or later, and HMC Version 7.7.3, or later, you can suspend an IBM i logical partition with its operating system and applications. When an IBM i logical partition is suspended, the state of the logical partition is saved on persistent storage, and the server resources used by the logical partition are made available for other logical partitions. The operation of the suspended logical partition and its applications can be resumed on the same system. The following information is new or updated for IBM i partitions with the Suspend/Resume feature:
- If you are using HMC Version 7.7.3, or later, you can use the command-line interface to override the default value of the HPT ratio. The following information is new or updated for the HPT ratio:
December 2010
The following updates have been made to the content:
- With the HMC version
7 release 7.2.0,
or later, you can suspend a running AIX or Linux logical partition with its
operating system and applications. Only POWER7 processor-based servers
support the Suspend/Resume feature. When a logical partition is suspended,
the state of the logical partition is saved on persistent storage,
and the server resources that were in use by that logical partition
are made available for use by other logical partitions. At a later
time, the operation of the suspended logical partition and its applications
can be resumed. The following information is new or updated for partitions
with the Suspend/Resume feature:
- Hardware Management Console terminal and console options
- Configuration requirements for shared memory
- Configuration requirements and restrictions for suspending a logical partition
- Verifying that the server supports partitions that can be suspended
- Verifying that the logical partition can be suspended
- Creating a logical partition with suspension capability
- Enabling the suspension capability of a logical partition
- Suspending a logical partition
- On the VIOS Version 2.2.0.11, Fix Pack 24, Service Pack 1, or later, you can create a cluster of only one VIOS partition connected to the shared storage pool and having access to distributed storage. The following information is new or updated for shared storage pools:
September 2010
The following updates have been made to the content:
- You can assign multiple virtual LANs (VLAN) to an already configured virtual Ethernet adapter that is being used by a running logical partition without restarting the logical partition. For a running logical partition, you can also remove or modify the VLANs. The following information is new or updated for modifying VLANs:
- You can configure the Quality of Service (QoS) priority levels for the virtual Ethernet adapter that is used by a logical partition. The following information is new for configuring the Quality of Service (QoS) priority levels:
- You can configure the MAC address controls assigned to a virtual Ethernet adapter and the logical Host Ethernet Adapter that is used by a logical partition. The following information is new for MAC address controls:
February 2010
The following updates have been made to the content:
- Information
was added and removed for servers that contain the POWER7 processor as follows:
- You can create a system plan by using the Hardware Management Console (HMC). However, the HMC does not collect VIOS provisioning information.
- You can deploy a system plan to a server by using the HMC. The HMC creates the logical partitions and configures their resources as defined in the system plan. However, the HMC does not deploy the operating system environment or provision VIOS resources.
- You can use the System Planning Tool (SPT) to create a system plan for a server that is managed by the Integrated Virtualization Manager. Then, you can use the system plan to help you order a system. However, you cannot use the Integrated Virtualization Manager (IVM) to view, import, export, create, deploy, or delete a system plan.
- You can use Operations Console to connect to IBM i logical partitions over a network (LAN connection). You cannot use the twinaxial console or Operations Console through a console that is attached to a serial port that is owned by the IBM i logical partition (directly attached connection).
- POWER7 processor-based servers do not support I/O pools for IBM i logical partitions.
- POWER7 processor-based servers do not support the high-speed link (HSL) OptiConnect feature for IBM i logical partitions.
- You can expand the
memory capacity of an AIX logical
partition by
configuring Active Memory™ Expansion.
With Active Memory Expansion,
the logical partition can do more work with the same amount of memory.
The following information is new or updated for Active Memory Expansion:
- Active Memory Expansion for AIX logical partitions
- Preparing to configure Active Memory Expansion
- Creating additional logical partitions
- Creating additional partition profiles
- Configuring Active Memory Expansion for AIX logical partitions
- Entering the activation code for Active Memory Expansion
- Changing the Active Memory Expansion factor for AIX logical partitions
- Adjusting the Active Memory Expansion configuration to improve performance
- With the HMC version 7 release 7.1.0, or later, you can activate a logical partition based on its current configuration instead of a partition profile. Logical partitions start faster when activated based on their current configuration data than when activated with a partition profile. The following information is new or updated for fast activation:
