Installing and Managing HP-UX Virtual Partitions (includes A.04.02)

• intctl command

The intctl command is a HP-UX tool that allows you to manage IO interrupts among the active

processors. It can be installed from the HP-UX Software Pack but should be used only by advanced

administrators for performance tuning.

If you are managing interrupts on vPars systems, please see the section “Managing IO Interrupts” on

page 187.

• kernel crash dump analyzer

You cannot use a kernel crash dump analyzer on Monitor dumps because vPars Monitor dumps are

structured differently than kernel dumps. For more information on Monitor dumps, see “Monitor Dump

Analysis Tool” on page 233.

• top and other applications that show CPU ID

The CPU ID displayed by the top command and other applications may not be indicative of the actual the

CPU index in standalone or nPars mode or of the actual hardware path. Within a virtual partition, top

sees only the CPUs assigned to it. Possible top output is shown below; the CPU index is the leftmost

column.
