Re: Can a HMC have an IMM

Jim, Dr,

Having read thru and done some board replacements (And noticing that some
CE's forget to re-set the type model on the replacement boards, which is
why HMC upgrades tell you to check it's set corrrectly) I find it hard to
believe either UEFI, IMM2 or any other part of the firmware could be
different. What I don't know how would work is getting the keys for the
IMM2 (We ARE talking about modern HMCs right? IMM2 based?) since I've only
done those keys a few times on X servers.
In any case if IBM says no, it's no, since you can't run PROD HMCs on
non-supported configs and expect support.
For Denis,
Maybe it's time to evaluate the cost difference between a vHMC and the
KVM....

Best Regards,
Roberto

I was trying to be polite, Rob.

As Larry pointed out (a bit less gently) the microcode on HMC appliances is
slightly different than if the hardware was a regular server so the IMM
behaves differently. You would not be able to get the 5250 screens nor the
GUI up and running. Hence my suggestion to use the virtual HMC instead.
VMWare has the KVM built into it so it completely eliminates the problem.

Well Jim, since the OP said
<snip>
We currently use an old IP KVM switch to access the HMC when we need to do
stuff that can not be done using the web interface, specifically starting a
5250 console session.

And you say
<snip>
Caveat: I don't believe you'll be able to start the console sessions or
GUI
etc, with the IMM, so be sure to have the remote sessions started.
</snip>

I hope, for the OP's sake, that your "I don't believe" is an absolute.

At work we are in the process of upgrading our three KVM's. Buying all new
and we scrambled like crazy to find ones which do not use Java. This has
been the reason our last two generations were retired. They stopped
providing updates and the Java got old enough that the browsers would no
longer function with them. It just a basic appliance for crying out loud.
Albeit a very expensive basic appliance.

The HMC is really just an Intel server in the end so yes you can use an
IMM.
Make sure to find the correct one for your model.

Caveat: I don't believe you'll be able to start the console sessions or
GUI
etc, with the IMM, so be sure to have the remote sessions started.

If you have VMWare you could just use the virtual HMC as well. That might
be
the smarter bet in the long run.

Subject: Can a HMC have an IMM

Hello all,

Do you know if an IMM (Integrated Management Module) is available for a
HMC?

Here is our situation.

We currently use an old IP KVM switch to access the HMC when we need to do
stuff that can not be done using the web interface, specifically starting
a
5250 console session.

This KVM switch is due to be retired and is used only to access the HMC.
All
other server have an IMM. I want to avoid having to by a new kvm just for
that.

Our business partner is proposing to use a virtual KVM, but this would
cost
us over 4000$.

The IMM would be the best but I can not find a source that can tell me if
this is an option or not for an HMC.

Any help would be appreciated.
