Hi,

Firstly has been a few years since I did this so bear with me if i'm asking stupid questions. Basically I need to create five lpars on my P520. I have set up the hmc and the server has been initialized. My question is do I need to use a VIO server to share the network and disk?

I think I do, as when I create a new lpar it asks me which physical controllers to add it gives:

Select U789C.001.DQD2J21-P1-T9 RAID Controller
Select U789C.001.DQD2J21-P1-T7 Universal Serial Bus UHC Spec
Select U789C.001.DQD2J21-P1-C4 PCI-to-PCI bridge

If I give the RAID controller to this lpar and then boot it no other will be able to use the disks. Is that correct?

Also are there any good guides for setting up vio and lpars out there? Also will my DVD drive on the P520 be part of my RAID controller?

with a p520 it's highly likely that you will not have enough IO adapters physical to implement 5 LPARs.

With Power6 machines I have seen, DVD/CD is part of the on-board scsi controller. But in older machines (power5), it was an IDE.

Hi,

It is a power 6 machine not sure about the cd drive ill check tomorrow, wouldn't using a vio server with virtual disk/io adapters solve the problem of physical adapters:

you can use the RAID controller, once you have the RAID controller for VIOS then you carve them into 5 lv and assign each lv to one lpar..similarly you have to use the SEA for the network.

Chris,
Short answer - yes you need vios, with HMC ideally you'll have dual VIOS.
p6 brings a few new toys into the mix like NPIV and HEA/IVE.
