Processor, Memory, I/O

View or change the memory, processor, and physical I/O resource settings for the managed system.

These properties include the following tabs:
Processor
The Processor tab displays information about the processors of the managed system, which includes:
  • installed processing units
  • unconfigured processing units
  • available processor units
  • available with stealable processor units
  • configurable processing units
  • minimum number of processing units per virtual processor
  • maximum number of shared processor pools
The Available with stealable field displays the information about the available processing units, which is the sum of the available processing units in the managed system and the number of stealable processing units.

The stealable processor units value is the sum of the processor resources that are assigned to all the powered off or hibernated partitions on the managed system.

Notes:
  • The information about stealable processor units is available only when the managed system is in the standby state or in the operating state.
  • If the managed system is licensed with Power® IFL processor and if the firmware level is at FW910, or later, the Available (with stealable) field is displayed.
  • When a Power10 system is licensed with some IFL processors, the tab also displays the information about the remaining processors that are available for running the AIX® or IBM® i partitions.
Memory
The Memory tab displays information about the memory of the managed system, which includes:
  • installed memory
  • unconfigured memory
  • available memory
  • available with stealable memory
  • configurable memory
  • memory region size with Current Value and Next Value fields that specify the current and next available value.
    Note: You can change the size of the Logical Memory Block (LMB) by changing the values in the Next Value field. The changes of this field are applied only after the next managed system restart.
  • current memory available for partition usage
  • system firmware current memory
The Available with stealable field displays the information about the available memory, which is the sum of available memory in the managed system and the amount of stealable memory resources. The tab also displays the maximum number of memory pools that are available.
Note: The information about stealable memory resources is available only when the managed system is in the standby state or in the operating state.
Physical I/O adapters
The Physical I/O Adapters tab displays the physical I/O resources for the managed system. The assignment of I/O slots and partition, the adapter-type, and the slot LP limit information are displayed. The physical I/O resources information is grouped by units.
  • The Adapter Description column displays the physical description of each resource.
  • The Physical Location Code column displays the physical location code of each resource.
  • The Owner column displays who currently owns the physical I/O. The value of this column can be any of the following values:
    • When a single root I/O virtualization (SR-IOV) adapter is in the shared mode, Hypervisor is displayed in this column.
    • When an SR-IOV adapter is in the dedicated mode, Unassigned is displayed when the adapter is not assigned to any partition as a dedicated physical I/O.
    • When an SR-IOV adapter is in the dedicated mode, the logical partition name is displayed when the adapter is assigned to any logical partition as a dedicated physical I/O.
  • The Bus Number column displays the bus number of the resource.
  • The I/O Pools button displays all of the I/O pools found in the system and the partitions that are participating in the pools.
