Re: Cutover from 820 to i5/520 -- MIDRANGE-L

Nope... Running the drives off the internal 5709 on the 520. The reason I 
stopped raid is that the new raid cards use a different stripe pattern. 
Then system will convert on the the fly to the new format, but I wanted to 
control when that happened.

The real point was that I was able to take "ALL" the configured DASD in my 
case and plug them in to the new system and IPL. I didn't need to do a 
loadsource migration or  an restore beacause I was able to bring all 8 of 
by 17gb 10K drives over.

But Kirk,
you did not move your "old" RAID controller, did you ?

Mike, I doubt that a 2748 will work in a 520, besides you have to have
another system frame (0595) for the number of disks you are moving.
The main system frame holds only up to 8 disks which are controlled by
the internal controller.

HTH,
Philipp
