I have two VPARs and all is fine.
Is there documentation on how to convert this into a 2 NPAR system and not use VPARs?
Solved! Go to Solution.

SolutionWith some luck the boot disk path are on the different npars. Just boot /stand/vmunix instead of /stand/vpmon.
If you need to relocate the disk, adjust the pathes in LVM -lm mode and vgexport/vgimport your boot disks to reflect the path change.
Hope this helps!

Torsten.

Re: Migrating VPAR to NPAR
Somehow missed the post.
There would be no conversion. You would need to rebuild the servers from scratch. With a bunch of prep work you may be able to export the data volumes and then re-import them. Beware that all the HW addresses will change as well as the FC assignments to the Npar. Big task to tackle.
( if this is in relation to the vrm failures, I would doubt that this would help as the vrms seem to be the biggest single point of faiure in HPs cell based systems ).
BTW, you would also loose the ability with workload manager to dynamically swap CPUs back and forth between vpars. There may also be an issue with ICOD depending on where the ICOD processors are located and in which cell ).
Best of luck.

Re: Migrating VPAR to NPAR
Device files are changing only, if you connect cables to different ports or cards or if you move HBAs around.
Let me assume you have a box with 2 cells (easy case) and 2 IO cages.
You can create 2 npars, each using 1 cell and 1 IO.
On a well configured vPar each vPar will use 1 path to a disk from each IO cage.
So every nPar should still have access to at least 1 disk.
Perhaps you need to adjust pathes you moved around.
But anyway, why you want to "convert" your vPars back to only nPars?
Hope this helps!
Regards
Torsten.
