RE: HMC Question -- MIDRANGE-L

I'll take a stab at this..........

It's similar to the Linux crowd you mention because the HMC is a Linux based
appliance.  It serves a specific function that only your sys admins should
have access to.  Its sole function in life is to manage the i5 in terms of
hardware configuration, etc.  It is not meant to be another server that
provides services to a base of users.  I think this is important to
understand from the very beginning.

As trivial as not plugging the i5 in until the HMC is fully functional
sounds, it is part of a process of installing an i5 as we know it today if
you choose the HMC.  Where we iSeries/i5 folks tend to get in trouble is
trying to treat it like the Windows based Ops Console (a.k.a. Oops Console).
If you have ever been burned by that product, you will understand what I am
saying here.....If a Linux appliance can do it better than that, I am all
for it!

It's really not a BIG deal as long as you aware and understand the process.
Since this is the first iteration of HMC for the i5, there will be more
improvements to the process over time.  But, it is what it is today.

Right, wrong, or indifferent, Linux is here.  And it does have its uses.
LinkSys routers like many of you probably use for wireless are running a
stripped down version of the Linux kernel.  Its how they have been able to
increase the security of the router because the firewalling is built into
the Linux kernel.

One can always stay with a twinax console if HMC is getting too geeky for
you! <VBG>

Anyone want to explain why?

I do not for a minute doubt any of this info, and I greatly appreciate 
receiving it.  I cannot help but think, however, how silly it is for a 
computer system being built in 2004 and costing hundreds of thousands of 
dollars can possibly be so sensitive to something so trivial.  I love the 
iSeries and would not want to work with anything else, but I sometimes 
think there are many aspects to it that are similar to the Linux crowd. 
Basically, there is this elite group of people that control it and they 
want to make it is inaccessible as possible to ordinary people.  A lot of 
you will object to hearing this, but that is only because you are already 
on the inside of that group.
