RE: OS400 DATA MIGRATION

I did my part.  I gave input, I made suggestions, I expressed concerns.

I hope that it works out but I think that you are going to have some
excitement both over the weekend and when the system comes back up.  Good
luck!

-|Guys,
-|
-|I'm not an expert with AS/400 hardware but I don't know where
-|50xx came from
-|in my previous posting, see my system storage resources below.  I know
-|these:
-|
-|1.    The new DASD (7 x 8.58Gig) is a type 6713 and all my
-|current DASD (12
-|x 4.xGig) is type 6607
-|2.    My current Storage controller for all 10 DASD is 6512 type.
-|3.    My current Storage controller for the 2 bottom DASD is 9162 type
-|(Combined IOP).
-|4.    IBM CE plan is to create another RAID for the new DASD (7 x 8.58Gig)
-|then perform Data Migration.
-|5.    The 2 drives will then be move to the bottom internal mirrored set.
