The Partition Load Manager can be used in partitions running AIX 5L Version
5.2 ML4 or AIX 5L Version 5.3. Linux or i5/OS support is not available.
A single instance of the Partition Load Manager can manage a single server.
However, multiple instances of the Partition Load Manager can be run on a
single system, each managing a different server or a different groups of
partitions on the same server.
The PLM cannot move I/O resources between partitions. Only processor and
memory resources can be managed by Partition Load Manager.
The PLM does not support dedicated and shared processor partition
managed in one group. You need a group for dedicated processor partitions
and a group for shared processor partitions.
Management of the Virtual I/O Server or Partition Load Manager partitions
using PLM is not provided.
The Partition Load Manager supports a single HMC. You can create a second
profile with the information of a second HMC, if one exists. In case of
problems with the primary HMC, you can switch the profile manually.
The Partition Load Manager requires the system to be managed by an HMC.
