HP-UX Virtual Partitions Administrator Guide (includes A.05.07) (5900-1229, September 2010)
To simulate a soft reset on only one virtual partition, from a running partition, use vparreset
with the -t (for TOC) option. For example, if winona2 is hung, we can execute vparreset from
the running partition winona1:
winona1# vparreset -p winona2 -t
The target virtual partition either shuts down or reboots according to the setting of the autoboot
attribute of that virtual partition.
Other virtual partitions are unaffected when one virtual partition is reset.
NOTE: Unlike the RS and TC commands, the vparreset command also displays Processor
Information Module (PIM) data unless the -q option is specified.
On Superdome, when there is a pending Reboot for Reconfiguration, the target virtual partition
will not be rebooted until all the virtual partitions within the nPartition are shut down and the
vPars Monitor is rebooted.
Using an Alternate Partition Database File
By default, the local copy of the vPars partition database is kept in the file /stand/vpdb on the
boot disk of each virtual partition within a hard partition. However, you can create, edit, and
delete virtual partitions in an alternate partition database file by using the -D filename option
in the vPars command string, where filename is the name of the alternate partition database
file. For more information on the vPars command strings, see the vPars manpages.
The alternate partition database file can be used to create an entirely different virtual partition
configuration without affecting the live partition database in the vPars Monitor’s memory or the
local copies in /stand/vpdb.
