Re: What's an IASP?

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

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.
