The vparenv -m ... command toggles the firmware mode between vPars and nPars mode on Integrity systems.

Set to vPars mode allows the system (the nPar) to boot vPars and vice versa.

vparenv -m vpars sets the next nPartition boot to boot into the vPars environment.

2.What changes does this command and when it needs to be executed?
To set the mode in order to boot into a specific mode (vPars or nPars) command needs to be executed.

Thanks for quick response.

You only need to do this if the system was in nPar mode before.

Starting the vPar environment in nPar mode will just fail (and vice versa).

if you use vparenv -m vpars in vPar mode, it will not affect anything. In case if you want to boot the server in nPar mode you have to type the command 'vparenv -m npars' and reboot the server. Now your server will boot up only npar mode untill you chnage mode using the command 'vaprenv -m vaprs'

For PA-RISC systems it is very easy to change the mode, if you boot the kernal /stand/vpmon, it will bootup in vPar mode and if you boot /stand/vmunix, it will boot in nPar mode.

Hope this clear.
