Disk space utilization

You Can View User Feedback To This Tip

Having high disk utilization problems? Where did all of that disk space go?

I run RTVDSKINF on each of my local AS/400's off of the job scheduler early Monday morning.

I then submit the PRTDSKINF *LIB command from the job scheduler at about 7:00 am.

When I come to work, I can check to see which libraries are consuming the system disk space by reviewing the spoolfile report QPEZDISK generated by PRTDSKINF.

This helps to locate, and keep the disk utilization lower.


  • This is good place to use the GO DISKTASKS utility on the iSeries. This utility seems to be rather obscure, which is too bad because it is very useful. — Deborah Lemly
