Some one please tell me how to set the partition to vPar mode
I know the below command will set the partition to npar mode from the OS
vparenv -m nPars .
As per my understanding after issuing the command if we try to reboot the system It will not boot .
Then How we can boot the system . How we will switch the partition to vparmode
Solved! Go to Solution.

Re: Set the partition to vPar mode
hpux /stand/vpmon -a. Then set vparconfig -m vpars and reboot the box. Box will boot in vpar mode during next boot.

Re: Set the partition to vPar mode
1 ) vparenv Unix shell command that allows you to set the mode (vPars or nPars) for the next
reboot of the nPartition or to set the memory granularity unit size in firmware
2 ) vparconfig EFI command that allows you to set the mode (vPars or nPars) and forces a reboot of
the nPartition.
Note that vparconfig is not a built-in EFI command; you will need to go to the
fsN:\> disk prompt to execute this command.
HPUX> boot vpmon
for PA-RICS the only way i gues is
BCH> bo pri
interact with IPL: y
ISL> hpux /stand/vpmon vparload -all
or ISL> hpux /stand/vpmon
MON>
The usage of booting into NPAR mode is to
upgrade the entire enclosure or do NPAR level modification like moving cells etc.

Re: Set the partition to vPar mode
Then you can assign and use the new CPU.
Hope this helps!

Torsten.

Re: Set the partition to vPar mode
As far memory allocation / reallocation for vpars is concerned you may not need to go to the npar mode.
Dynamic Memory allocation :-
This is called Dynamic Memory Migration, and is possible in vPars software versions A.05.01 and above. Memory must be configured as Base or Float. Base memory can be added while the vPar is running, but not removed; Float memory can be added or removed. Unless specified otherwise, all memory assigned to a vPar will be assumed to be Base memory.
exapmples :-
#vparmodify -p pcvp1103 -d mem::8192
#vparmodify -p pcvp1103 -a mem::8192:float /base
CPU Allocation :-
At vPars software version A.04.01, the distinction of Bound/Unbound CPUs was removed.
With the newer versions, one of the vPar's processors (cores) is designated as the Boot processor; all the rest are Dynamic. You cannot remove the Boot processor (core) from the vPar without shutting down the vPar; you are free to add/remove any of the Dynamic ones while the vPar is running, if you wish.
In vPars software A.03.xx, you can only add or remove Unbound CPUs while the vPar is running; to add/remove Bound CPUs, the vPar must be stopped.
So it looks most of the work can be done
at vpar level .If we are assigning resources
between npars ,like moving cell boards ,
adding cell based based memory we need to go down to npar mode.
Suggest you to read the docs below :-

Re: Set the partition to vPar mode
From any one of the vpar you can give the command
vparenv -m nPars
The do the shutdown -hy 0 in all the vpars
Then go to the MP menu and boot only the npar which you required to got to npar mode.
Interrupt at the EFI level and boot to /stand/vmunix
Then it will be booting to the nparmode
