HP Superdome 2 Partitioning Administrator Guide (5900-2540, December 2012)

To poweroff a virtual partition from the OA prompt, do one of the following:
◦ For graceful shutdown type:
poweroff partition 1:1
◦ For ungraceful shutdown (required whenever the partition is at the UEFI prompt) type:
poweroff partition 1:1 force
• To reset a virtual partition invoked from the OA:
reboot partition force 1:1
• To simulate a hard-reset, use the -h option:
vparreset -f -p 1:1 -h
or
poweroff partition 1:1 force
• To simulate a TOC reset, use the -t option:
vparreset -f -p 1:1 -t
or
vparreset -f -p 1:1
or
INIT partition 1:1
NOTE: On SD2, a vparreset always forces a crash dump, irrespective of whether the -t option
is used or not. If you prefer to avoid the dump, perform a hard-reset (vparreset with the -h option)
and follow it up with a poweron of the vPar to bring it up again.
Shutting down all Virtual Partitions
You can shut down all the virtual partitions within a hard partition when there is a hardware
problem, or when the nPartition modification requires the nPartition to be down. To gracefully
shutdown all the virtual partitions in an nPartition, run the following command:
poweroff partition <npar_id> OVERRIDE
To ungracefully shutdown all the virtual partitions in an nPartition, run the following command:
poweroff partition <npar_id> OVERRIDE FORCE
Managing: Removing a Virtual Partition
To remove a virtual partition, use the vparremove command to purge the virtual partition from
the parspec. Any resources dedicated to the virtual partition will be freed and can be allocated
to a different virtual partition.
You must shut down the virtual partition before removing it. If the target virtual partition is running,
vparremove will fail.
Example
To remove a virtual partition named vPar0001:
1. Login to the OA.
2. The partition must be in the Down state.
vparstatus -N nPar0001 -p vPar0001
If the virtual partition is running, it can be shutdown from the OA using poweroff command,
or from OS by running the following commands:
