HP-UX Virtual Partitions Administrator Guide (includes A.05.09) (5900-2188, March 2012)

NOTE:
— If a virtual partition has its autoboot attribute set to MANUAL, the virtual partition will only
halt and will not reboot when the command shutdown -r (or reboot -r) is given. For
more information on the virtual partition attributes, see the vparmodify(1M) manpage and
“Managing: Modifying Attributes of a Virtual Partition” (page 147).
— 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 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 have been shutdown
and the vPars Monitor has been rebooted.
— When you need to force a non-graceful shutdown, such as when a partition appears hung,
use vparreset. See “Resetting a Virtual Partition” (page 161).
— The shell commands shutdown and reboot apply only to the OS instance of the virtual
partition from which they are executed and do not shut down or reboot any other virtual
partitions or the vPars Monitor.
— There is no command to shutdown the vPars Monitor. The vPars Monitor command reboot
(see “vPars Monitor: Using vPars Monitor Commands” (page 128)) applies to the entire hard
partition, causing the hard partition to reboot. For more information on how to shut down or
reboot the hard partition gracefully, see “Shutting Down or Rebooting the nPartition (Or
Rebooting the vPars Monitor)” (page 149).
When to Shutdown All Virtual Partitions
The only times you need to shutdown all the virtual partitions within a hard partition are when:
• a hardware problem or nPartition modification requires the nPartition to be down. Note that
PCI OL* is supported on vPars A.03.xx, A.04, and A.05.
• the entire hard partition hangs. This might be a problem with the vPars Monitor.
• you need to update the vPars Monitor (/stand/vpmon)
Shutting Down or Rebooting the nPartition (Or Rebooting the vPars Monitor)
Usually, you need to reboot the vPars Monitor whenever the granularity values are modified.
To halt or reboot the hard partition gracefully, you need to do the following:
1. Log into every virtual partition that is running and gracefully shutdown the partition via the
HP-UX command shutdown.
There is no command that shuts down all the virtual partitions at the same time. You need to
shutdown every virtual partition one at a time.
For our example, if all our partitions were up, we would need to shut them down:
winona1# vparstatus
winona1# shutdown -h
winona2# vparstatus
winona2# shutdown -h
winona3# vparstatus
winona3# shutdown -h
2. After the last virtual partition is shut down, you will be at the vPars Monitor prompt (MON>)
on the console.
