Managing Hardware Resources

  • I/O Allocation (Adding or Deleting I/O Resources)

  • Memory Allocation (Firmware Configuration and Adding or Deleting Memory Resources)

  • CPU Allocation (Adding or Deleting CPU Resources)

  • Using iCAP (formerly known as iCOD) with vPars

  • CPU Monitor (deallocation and deconfiguration)

NOTE: Some examples in this chapter may use a non-nPartitionable system where there is no cell in the hardware path. If using an nPartitionable system you must include the cell in the hardware path; for details see “Planning, Installing, and Using vPars with an nPartitionable Server”.
