Problem to booting up p730

Hi Everyone,

We have IBM p730 that I am trying to booting up to AIX 7.1.
But it stops at RUNTIME.

C7004087
C7004091
C7004091 (show is code number twice)
STANDBY
RUNTIME

The explanation for C7004091 is the final IPL status progress code to be displayed before the system reaches standby state. I don't see anything from HMC events logs.

Please help!
Thanks.

I am not exactly sure what you mean: you boot the managed system - OK. You need to create and/or boot an LPAR profile to boot AIX and you probably need one (or two) VIO-server. Or are you using the system in full system partition mode?

Please explain a bit more detailed what exactly your plan is (and how it is not working for you).

I hope this helps.

Hi bakunin,

Sorry, I don't know much about IBM/AIX server to explain more :frowning:
I purchased the server with pre-installed AIX 7.1 last year (have not powered it on). It's supposed to boot directly to AIX OS but this server stop at that point.

Does it mean the server does not see the boot partition?

Thanks,
Lily

Sigh!

OK, short introduction to IBM POWER servers:

These systems are NOT intended as single systems, like a PC is. They are built with virtualisation in mind. It is possible to use them as physical systems, but this is highly unusual. Normally you use them to start LPARs (logical partitions, virtualised systems).

Virtualisation comes in two parts: memory and processors are easy to share, because they are "anonymous" resources. A GB of memory is a GB of memory and you can move it from one system to the other easily. Other resources like disks, network cards or other adapters are not that anonymous, because they actually have a certain content which makes them individual. It is therefore not possible to manage them like you do manage contentless resources.

For this IBM has created the VIOS (virtual I/O server). VIOS are LPARs like all the others, but they are installed with a specially adapted AIX (called IOS). VIOS get the physical resources installed in a machine, then are used to create virtual adapters. Suppose network cards: the most common setup is to have two network cards in a physical system (which is called "managed system" in IBM speak). You create two VIOS (for redundancy) and give each one of them one network card. From these two a so-called "SEA" (shared ethernet adapter) is created, which is basically a sort-of-clustered adapter (two VIOS are basically a failover cluster). When you now create another LPAR you create a virtual ethernet adapter and give this to the LPAR. The hypervisor (which in a POWER system is hardware-based, which is why it is so immensely fast) acts as a "bridge" so that all traffic you see on the LPAR is handled by the physical adapters in the VIOS systems. You do the same with fibre channel adapters or SCSI adapters, so that ou can use SAN LUNs as boot disks for LPARs. VIOSes can take a SAAN LUN, give out a virtual SCSI adapter to an LPAR and attach the SAN LUN as virtual SCSI-disk you can boot from without need of any further driver - for the LPAR it is a real SCSI disk, complete with SCSI ID, etc..

Because all the resources a "normal" (not-VIOS) LPAR sees are virtual it is possible to shift systems from one managed system to another even while running full steam. This is called LPM (live partition mobility) and it is done regularly.

OK, after this short (real short - i suggest to read some red books for a few more details) introduction, here is what you need:

You first need to install the HMC. The HMC (hardware management console) is separate physical system (basically a PC with Linux) and it is connected with all the service ports (in IBM speak: service processors) on a separate network. This network should NOT be routed anywhere, because the HMC
acts as a DHCP server (so to say - the tampered with the DHCP protocol, but that is another story). Furthermore the HMC needs a network interace into your normal network, because you usually use its web interface and its CLI via a terminal emulation.

Next, you start the managed system once you have its service processor(s) connected to the HMC. Run a discovery on the HMC to see it there.

Look if any LPARs are defined on the system. If not, you need to create two LPARs for VIOS and install them. Only then you can create more LPAR profiles (these define virtual systems) and install these with AIX.

Notice that all these things take time: it is quite tricky to create the right network setup for the physical adapters, especially when you have VLANs in your LAN as most bigger shops do. There is a lot of planning involved and if you know nothing about AIX and IBM virtualisation you are highly likely to not get it done. You may want to hire a consultant to do it for you and/or book some courses at IBM to learn how to do it. Even if you exactly know what you do it will easily take a week to plan and implement such a system because there is a lot of cross-department-work involved: network, SAN, datacenter management, and so on.

I hope this helps.

Thanks bakunin

Did you get it started?

If not, even though I don't have a POWER7 system handy - I'll try and help you get it operational in "Bare Metal" mode.

Basically, if the LCD panel is saying HMC=0 then it is still waiting for an HMC to be connected. You need to attach via the ASMI (web interface) and do a firmware reset - so it forgets about HMC's.

You will also need a (serial) console or a USB keyboard plus regular (EVGA?) screen so you can accept license after the reset.

Hope you are already having a great time!
