vpar decommission


how do one decommission a 11.23 vPar?


superdome has  four nPars

one of the nPars has six vPars.

one of the vPars is to be decommissioned.


This to be decommed vPar has two processors, many disks and RAM.



MON> vparinfo

Names of the partitions in the database:



vpar1 (up) ==> need to decommission this vPar

vpar2 (up)

vpar3 (up)

vpar4 (up)

vpar5 (down)

vpar6 (up)

Re: vpar decommission

You can just vparremove the vpar.


Note however that there is a possible complication if the vpar to be remove owns the monitor boot disk

(compare vparstatus -v and vparstatus -m). In that case I'd recommend to boot the monitor (the npar)

from some other partition's boot disk first (and change the EFI boot path accordingly) to prevent problems.

Re: vpar decommission


As it is vpar number 1, I have doubts that it could be the one holding that monitor/ vpdb disk

I am not sure how to check that though.


I attached vparstatus -v and vparstatus -m


executed the commands from vpar1

Re: vpar decommission

Monitor boot disk path:
[Virtual Partition Details]
Name:         vpar2
State:        Up
[IO Details]

So the monitor's boot disk is under 1.0.14 which is owned by vpar2. So no problem for removing vpar1.

Interestingly, there is no boot disk defined for vpar2. You should get that addressed.

Re: vpar decommission

great, Stan.... thank you... learnt something new today..


so, you reckon, I can go ahead and vparremove -p vpar1 from any other vpar now..


1. By the way... how do I format those disks associated with vpar1.. ? So many many disks in that vpar!

that is one the requisites in decommission work....


2. I noticed BOOT and ALTBOOT not present in IO Details in other vpars.. vpar3, vpar4 an vpar6 (vpar5 is down)

     Need to address these too?

Re: vpar decommission

Also...very important question What needs to be done, if one has to decommission a vPar where monitoting boot disk is also present in that vPar's IO details..? thank you
