1. Freeing up disk on your IBM i

2. Traditional items
Spool files
Ptf save files

3. RTVDSKINF Your first line of attack
The Retrieve Disk Information (RTVDSKINF) command is used to collect disk space information. Disk space information can then be printed using the Print Disk Information (PRTDSKINF) command. The collected information is stored in a database file in library QUSRSYS. The file name depends on the auxiliary storage pool (ASP) device for which disk space information is retrieved. If the information was retrieved from the system and basic ASPs, the collected information will be stored in file QAEZDISK. If the information was retrieved from an independent ASP device, the collected information will be stored in file QAEZnnnnn, where 'nnnnn' is the ASP number of the independent ASP. The information will be stored in a data base file member named QCURRENT.
Each time this command is run, existing information in QCURRENT is written over. To save existing information in member QCURRENT, rename file QAEZDISK or QAEZDnnnnn, or copy the member to another file.
Note: Do not rename member QCURRENT within file QAEZDISK or QAEZDnnnnn. If there is more than one member in QAEZDISK or QAEZDnnnnn, the results of running this command can be unpredictable.

4. RTVDSKINF more small print
Restrictions:
1. You must have all object (*ALLJOB) special authority to collect disk space information.
2. You must be enrolled in the system distribution directory to collect folder and document information. Use the Work with Directory Entries (WRKDIRE) command to enroll.

What you knew in the past may still be important, but, start with the above first to get the biggest bang for your buck.

54. Hip Shots Keep your /QIBM/UserData/OS400/MGTC/service directory clean.
Watch your journal receivers.
If a Domino shop consider:
R8 compression
DAOS
Archiving
clearing out your IBM_TECHNICAL_SUPPORT directory
