Announcement Support for this product will end on November 3, 2025. We recommend that you use PATROL for Linux, PATROL for AIX, or PATROL for Solaris to monitor operating systems.

AIX_VIRTUALIZATION

The AIX_VIRTUALIZATION application class monitors requests for the following types of processor logical partitions provided with the IBM AIX micropartitions on the POWER5 (p5) series of servers:

  • Logical partition (LPAR)
  • Dynamic logical partition (DLPAR)
  • Shared processor logical partition (SPLPAR)

In LPAR, individual processor, memory, and I/O adapter slots are monitored under the exclusive control of a logical partition. If you make any change to the LPAR resource allocation, you must reboot the partition for the change to be effective.

DLPAR allows fine-grained resource allocation and deallocation while activating a logical partition, and also when the partitions are running. In DLPAR, individual processor, memory, and I/O adapter slots are released and acquired from a "free pool," or moved directly from one partition to another.

In SPLPAR, the processor capacity is specified in processing units; one processing unit represents one percent of one physical processor. Shared processors form partitions using micropartitioning technology; the minimum capacity is 10 processing units, or 1/10 of a physical processor. SPLPARs are defined with the CAPPED and UNCAPPED attributes. A capped SPLPAR is not allowed to exceed the defined capacity. An UNCAPPED SPLPAR, however, is allowed to consume additional capacity.

This application class does not provide any menu commands because it automatically detects and monitors the partitions. It gathers and stores vital statistics in its parameters. Tasks for accessing information stored in the AIX_VIRTUALIZATION parameters are described in the following sections:
