dukessd is absolutely correct! You are doing it all wrong because you do not understand:

OK, but most critical: where are the (physical) SCSI adapters? The way you describe it you do not even have one and how are the disks supposed to be connected to the system, hm? dukessd said already that you probably have only one SCSI adapter and this is already taken by the first system you install.

No, i meant what i said: Linux virtualisation is: take some hardware, install Linux, install some software (for instance "Openbox") on top, then create several instances of running Openbox-processes (aka "virtual machines"), then install some OS of your choice into each of these virtual machines.

IBM virtualisation is: connect the MS to the HMC, create some LPAR profiles and install into each LPAR an OS. The "HW-host-OS-virtualisation-software" part of a virtualised Linux system is all in hardware.




Yes, because you seemingly have only one SCSI adapter, for chrissakes! You can add this adapter to several LPARs in the same way you can promise the same 10-Dollar-bill to several people. But finally, either you are going to have as many bills as people you made a promise to or all (except one) are going to be very disappointed. What you see is a LPAR which you have promised a SCSI adapter which it cannot get because you gave it to another system first. Switch off the first LPAR and you perhaps can boot the second LPAR without a problem (but as long as it runs you will not be able to boot the first - for the same reasons).

Well, i run some 40 managed systems with about 300 LPARs distributed on them, more or less the whole midrange IT of a big bank. I dare say if the system would be so bad as you describe that should not be possible. I might start with

which is a non-supported setup. You might not know that, because reading the documentation is below real experts, but this - along with several other necessary things you may not have done and things you didn't do according to the requirements - may also have led to your frustration. It takes very little creativeness from my side to come up with a possible course of action leading to the problems you encounter.

So you might want to reconsider your take on this and start with learning and only critisize things you have a well-founded knowledge about.

I hope this helps.

just to give you guys a status report, I've installed VIOS, and logged in to it with padmin..
I get what's going on now..it's basically the same as ldom creation in Oracle solaris.
ldm add-vdsdev
ldm add-vdisk
ldm add-vnet
similar concepts: backend file or volume.create the virtual device for it, assign it to a
LDOM ( or Lpar in IBM verbage), etc..
so it all makes sense to me now..
I can't see any virtual SCSI server adapters yet with lsdev -virtual, only the serial connections.I'll have to add them manually.I've created a VG with mkvg , a logical volume, etc..getting the hang of it.
we do have to get the power installed for the enclosures but at least I can mess around with this just to get my feet wet..
definitely prefer command line to gui.

Most probably because you haven't created one. See the "mkvdev"-command.

I hope this helps.

It's very deep water you are getting into but it is the best, welcome to the world of PowerVM ;0)

sounds good. did managed system restart help?

yes, you have to add them manually in LPAR's profile definition. After that you have to _shutdown_ and start the LPAR again. Notice - not restart, but shutdown and start. If you have configured everything correctly and have luck, you can use Dynamic Partitioning -> Virtual Adapters menu in HMC without shutdown/starting the LPAR, but I don't believe. Anyway you should update your LPAR profile.

After that if you managed to everything right, you will see something like this in the output:

Code:

vhost0           Available   Virtual SCSI Server Adapter

Hi everyone
KGB I have managed to create 2 AIX 6.1 VMs, as well as a VIOs server ( created it first). each has a rootvg of about 130GB in size , basically taking up one physical 136GB disk on the 8202..
.I have two virtual ethernet adapters going from VIOS to each VM .vm #1 works perfectly well, is networked and we're having no problems with it. AIX 6.1 VM #2 is unable to see the network.I have set up the DNS server with the hostname and the ipaddress ( 10.10.1.68,devrs8).
I have created add'l ethernet adapters on VIOS, rebooted it so they are 'seen' by LPAR #2, rebooted LPAR #2, and I've tried to configure ( on the AIX 6.1 OS) ,one and all at different times without any luck.they are there, they just don't like to ping any remote system.I can ping the above address I give it, or 127.0.0.1 but nothing else. def route has been set.
tried using ifconfig, smit, mktcpip, I even tried to use DHCP.no luck.even re-installed the OS to get a clean slate to work with, and I'm stuck at the same thing.
dns
10.10.1.6 10.10.1.7
IP=10.10.1.68
def route 10.10.1.1
netmask 255.0.0.0

any advice on what might be the cause?

The way you deescribe it the problem is not the adapters in itself. In typical setups you give the physical adapters to the VIOS(es), create virtualised adapters for the other LPARs and have the VIOS act as a virtual switch to connect these layers.

You being unable to get outside the system means you probably have got the setup of this part wrong or not at all. You need to set up VLANs both for internal and external networks and "connect" these on the VIOS. See the documentation, especially "SEA" and "HEA", for details about the concepts involved.

I hope this helps.
