vpar extend memory

[Stijn V]

I only have one vpar within an npar and I would like to extend the memory...

But how do I do that when I bring down the vpar?

#vparmodify -p -m mem::15805

[Torsten. · Accepted solution]

With only 1 vPar you need to boot to non-vpar mode and modify from there.

Boot /stand/vmunix instead of /stand/vpmon from the firmware boot interface!

please find detail procedure

# shutdown -hy 0


# login to d203 and check vparstatus

Nice procedure Sandeep - but how to make this with only 1 vPar?

Stijn V, do you know how to boot into non-vpars mode?

It depends if you have a RISC or Itanium based machine.

[Sandeep_Chaudhary]

sorry !!!!! not read question properly

[Stijn V]

Thanks Torsten.

don't realy know how to boot in npar mode (it's an Itanium RX7640).

And if I boot in npar mode, I just can launch the vpar commands?

[Sandeep_Chaudhary]

For integrety server:
If you are at EFI shell prompt, use the following EFI utility to switch to either nPars or vPars mode:


Shell:> fsN:
fsN:> vparconfig reboot mode



Since vparconfig is not a built-in EFI shell command, you must go to the disk to execute vparconfig. For example, to switch to vPars mode:


Shell:> fs0:
fs0:> vparconfig reboot nPars



1 Access the EFI partition of the disk.

2 Set the mode and reboot the system.

After u boot in nPar mode from there u can able to execute vparmodify command (with -D option as the vpardb is down at the moment)
