Installing and Managing HP-UX Virtual Partitions (includes A.04.03)

Introduction

HP Product Interaction

Chapter 1

Also, if a virtual partition is not set for autoboot using the autoboot attribute (see the vparmodify (1M)

manpage), the -r and -R options of the shutdown or reboot commands will only shut down the virtual

partition; the virtual partition will not reboot. In other words, the virtual partition will halt when the

autoboot attribute is not set. For more information, see the vparmodify (1M) manpage.

For the -R and -r options of the shutdown and reboot commands, the virtual partition will not reboot

when there is a pending reboot for reconfiguration (RFR) until all the virtual partitions within the

nPartition have been shutdown and the vPars Monitor has been rebooted. Also, the requested

reconfiguration will not take place until all the virtual partitions within the involved nPartition have

been shutdown and the vPars Monitor has been rebooted.

For more information, see “Boot||Shut: Shutting Down or Rebooting a Virtual Partition” on page 130 and

“Boot||Shut: Shutting Down or Rebooting the nPartition (OR Rebooting the vPars Monitor)” on page 132.

• ioscan output

On a PA-RISC system, the ioscan output for vcn and vcs drivers show a value of NO_HW in the S/W State

column. This is normal.

• 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 182.

• 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 237.

• 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.
