Re: What's an IASP?

James,

Console and 5250 attachment is completely independent of an iASP, so there is no consideration there. You do not need any additional software in order to create an iASP and use it. That only comes in if you want to replicate it with PowerHA, or use one of the other clustering techniques for higher availability or continuous availability.

What you will need is one or more disk unit(s) that is/are not in the current system. You can remove one of your existing drives from the system if you have the space, and the drive can be a part of any raid set. Since you are using mirrored pairs I think you'll need to take a mirrored pair, so it might be better if you can to add two more drives. Not knowing the system, I can't help you with if that's reasonable or not.

A VLP might be a very good way to do some experimentation without upsetting your current system.

One other question:

Suppose (hypothetically, at this point) we decided we wanted to set up
an IASP on our V6 E4A, in order to determine whether we needed to write
a snakebite* (snakebyte?) kit for our products.

As a "terminal/emulator shop," that has a definite preference for either
the TN5250 client we developed in-house, or a real terminal, we
basically have only the barest minimum Lan Console and iNav.

What LPPs would we need? (And are they expensive, cheap, or free?) And
would we need to put in an additional drive (we have no user ASPs, and
our system ASP is at 30%, and we currently have 4 physical drives, in
two mirrored pairs), or could we carve space out of the System ASP?

Or is it something better experimented with on a VLP box?
