Re: Adding 2 8GB drives into a 170's existing RAID set

You know, I run newer hardware and operating systems, but I've never had 
to IPL to add harddrives to a parity set.  And, I never select simply Add 
to ASP.  Further down that menu you'll see Add to ASP and Balance data. 
Which is supposed to do a STRASPBAL.

Now, a week later or so, I may do a TRCASPBAL, followed by a STRASPBAL 
based on usage instead.  That can make a performance difference.

Then again, in the old days we would do a complete save and restore to 
balance the data across all arms.  But even that doesn't really base it on 
usage.  That's still pretty much capacity.
