 RCLSTG Command
DataCenter
I'm guessing this is a loaded question, but is there anyway to estimate the amount of time it will take to run a Reclaim Storage? We have a 9406 model 820 running V5R1 with 300gb of disk available and about 40% of that is being used. Aside from the amount of time it will take, are there any other special considerations that need to be taken into account?

Answer Wiki:
Your system must be in restricted mode (ENDSBS *ALL). Your users will be off, also all your scheduled jobs will be on hold. When the command is done, you will have to manually start all the scheduled jobs that would have run during that time. I used to run the command bi-annually, but stopped about 4 releases ago. The reason: it never "reclaimed" any lost storage. If an object is reported "damaged", delete it and restore it from backup.

Unless you are getting instructed from IBM to run this command – you shouldn’t be. A few releases ago, I will admit it was recommended – but since i5 it is not.

If you are interested in problems with the database portion of your system, you can run the RCLSTG *DBXREF option without any negative impact. Be sure to check some of the online knowledge base docs for additional info.

To answer your original question – I’m not aware of anyway to estimate the time for that command. I have seen it run in as little as 6 hours and as long as 28 hours. You can’t end it once it starts without doubling your time, so be careful.
