Reclaim Storage and clean up before server upgrade
At the moment our AS400 takes 1.5 hrs to IPL, 20hr to do a reclaim storage and about 4 hrs for the full backup. We need to shorten the time it takes for these processes to complete, so first we need to clean-up before we look into upgrading this server.

Answer Wiki:
hi,
Before reclaim Storage you will do some activity. rcldlo, rclsplstg, stop the performs & Clrlib lib(qmpgdata), clrlib lib(qpfrdata), clrpfm, then you will start the rclstg.
Thanks

What model AS/400? What version of i5/OS is currently running? How much DASD and what percentage is used? How much memory?

I did not see a question.
Are you asking how to cleanup the system?
A “cleanup” might make no significant difference. What might make the biggest difference is simply to cut RCLSTG out of the picture since it serves no purpose for an upgrade.
The IPL time isn’t likely to change much after any cleanup. It’s a concern, though, because it’s been quite a while since I’ve seen such a long IPL time. It might indicate older equipment or related issues.
And backups — with no picture of the environment, who knows how long they should take? How much could be saved? What media and devices are used?
For many sites, one of the biggest drags on save times is private authorities. But how would that be covered under “cleanup” in this case? That should be a project (or three) by itself.
OTOH, if the upgrade is from V5R4 to V6R1 (V6R1 to V7R1?), and it’s scheduled for, say, November…?
