v
vpmon(5) vpmon(5)
This option is available on Itanium-based platforms only. It is mutually exclusive
with the -b, -B, and
-D options.
This option is provided as a tool to boot a vPar only if a valid HP-UX h/w path to
EFI path mapping is not present in the virtual partition database for a boot disk.
Refer to vparefiutil (1M) for additional information on HP-UX h/w path to EFI path
mappings.
This option is not recommended for general purpose use. If virtual partitions are
configured as per the documented procedure, there may not be a need to use this
option to boot a vPar.
clear_pending
The clear_pending
command can be used to clear the pending reboot for reconfiguration flag. If the
pending reboot for reconfiguration flag is set, the user will not be able to boot any virtual partition until
the monitor is rebooted. If this flag has been set in error, the
clear_pending
command can be used to
clear it thus enabling virtual partition boots.
threads [on|off]
The
threads command will display, enable, or disable hyperthreading. With no arguments, the com-
mand displays the current state of hyperthreading and what the state will be after an nPartition reset.
When on or off is given as an argument, the command changes the hyperthreading setting. However,
an nPartition reset is required before any change takes effect.
readdb filename
The
readdb command can be used to read an alternate valid partition database filename for partition
configuration information.
filename must be an absolute path and reside on an HFS file system.
This command may only be used when the
vpmon /stand/vpmon is booted and one or more of the fol-
lowing conditions exist:
• The default partition database (
/stand/vpdb) does not exist, or
• The alternate partition database as specified in the
-D option of /stand/vpmon does not exist, or
• The database file read is corrupt.
reboot [mode]
The
reboot command will reboot the entire hard partition. Other hard partitions are not affected.
Each virtual partition should be shut down prior to invoking the reboot command. A confirmation prompt
is provided. However, if you accept confirmation of the reboot while any virtual partitions are running,
the
reboot command will bring down the running partitions ungracefully.
The valid values for the optional argument mode are
vPars and nPars. If mode is specified as
vPars,
after the reboot, the system will be in the vPars mode. If mode is specified as
nPars, after the reboot,
the system will be in the nPars mode.
The argument is case-insensitive.
This optional argument is applicable for Itanium-based platforms only.
toddriftreset
The toddriftreset command resets to zero the time of day drift value of all the virtual partitions.
On a standalone system, the OS will own the real time of day clock. In
vPars, the vpmon emulates the
time of day clock for each virtual partition. To do this, the vpmon keeps track of the drift value, which
indicates how much the real time of day clock differs from each virtual partition’s current time value. If
the user were to make any changes to the real time of day clock at the BCH prompt, the drift value
becomes invalid. In this situation, the user may use this command to set to zero the drift values for all of
the partitions.
monadmin [-S on|off]|[-a|-d vpar_name ]|[-l]
The
monadmin command enables the MP (Management Processor) user of an nPartition to enable or dis-
able the virtual partition flexible administrative capability and also to designate zero, one or more virtual
partitions to have administration capabilities (Designated-Admin vPars). A Designated-Admin vPar
can create, boot, reset, modify, and remove vPars other than itself. A non Designated-Admin vPar is
