Logical partition

8 rows · AIX logical partition virtual machine technology is released by IBM with AIX as a full virtualization solution. LPAR differs from other popular alternatives like Xen and VMware in terms of operation, performance and flexibility. LPAR comes as a kernel module, with a set of user space utilities to create and manage logical partitions (LPARs). Oct 21,  · Let’s just stick with the name and then list all the LPARs that are associated with each managed system. I’m assuming that the hostname of the LPAR is the same as the LPAR name on the HMC, or at least the LPAR name contains the hostname. If not, you’d probably need to match up the LPAR ID, which is beyond the scope of this article.

Sharing of resources between LPARs enables more efficient utilization of physical resources and facilitates consolidation. Workload Partitions enable administrators to virtualize the AIX operating system, by partitioning an AIX operating system instance into multiple environments. WPAR is a pure software solution and has no dependencies on hardware features. Shat Partition Mobility enables greater control over the usage of resources in the data center by enabling the migration of a logical partition from one physical system to another.

This feature enables the transfer of a configuration from source to destination without disrupting the hosted applications or the setup of the operating system and applications. Live Application Mobility enables the planned migration of workloads from one system to another without interrupting the application and can be used to perform a planned whay installation on a server.

Active Memory Sharing is a virtualization technology that enables multiple partitions to lpad a pool of physical memory.

AMS increases system memory utilization and reduces the amount of physical memory that the system requires.

Active Memory Expansion relies on compression of in-memory data to increase the amount of data that can be placed into memory.

The operating system manages the in-memory data compression, which is transparent to applications and users. The memory is effectively broken up into two pools - a compressed pool and lpzr uncompressed pool.

The operating system dynamically varies the amount of memory that is compressed, based on the workload and the configuration of the LPAR. These reference configurations can be customized to fit most implementations. An assumption is made that the reader understands the AIX operating system, including its architecture, as well as how to configure and manage LPARs using the management software already provided by AIX. There is also an expectation that the user is familiar with the basic Veritas Storage Foundation and High Availability Solutions software and is well versed with its administration and management utilities.

Mar 24,  · A logical partition (LPAR) is the division of a computer's processor s, memory, and storage into multiple sets of resources so that each set of resources can be operated independently with its own operating system instance and application s. The number of logical partitions that can be created depends on the system's processor model and resources available. Description The lparstat command provides a report of LPAR related information and utilization statistics. This command provides a display of current LPAR related parameters and Hypervisor information, as well as utilization statistics for the LPAR. An interval mechanism retrieves numbers of reports at a . AIX LPAR and VIO server both are Virtual Servers hosted on IBM Frame. AIX LPAR - we treat them as and AIX server and runs application on them. VIO Server = Its is customized AIX box and we treat them to virtualize the physical resources (Hardware) to assign them to multiple LPARS.

When the environment is spread across several sites, it can be a challenge even identifying which HMC to log onto to manage a particular LPAR. I recently had this situation. You may have the opposite challenge. ManagementServer instead of IBM. Profile changes take effect when the LPAR is shut down and the new profile is activated. From the HMC command line, here is the command to run:.

This will give you just the server names as indicated by the -F flag. You could display the server model number and serial number as well using:. We need to change the flags on the lssyscfg command within the loop to display the LPAR name. You can add a grep command to filter to the LPAR that you want.

Although the HMC command line syntax is pretty unwieldy and hard to remember, it does come in handy when you have to check larger environments and the browser-based interface would be too slow. You can check the syntax for the HMC command line in the links below.

It is helpful to get a little familiar with the HMC command line, especially with the command to list the configuration lssyscfg. If you do, you can gather information about your environment into a CSV format.

This can be pretty handy if you need to upload the configuration information into a spreadsheet or a database. He is a well-recognised author in the field of IT, and has some unique perspectives on technical and business-related topics. Anthony is based in Sydney, Australia with his wife and seven young children. From the HMC command line, here is the command to run: lssyscfg -r sys -F name This will give you just the server names as indicated by the -F flag.
