You could try the RTVCFGSRC.
You could try WRKDEVD and 3 to copy.
I'm concerned that since you can only do this on a Wednesday that it would
just burn another week if this doesn't resolve it.
Another option is to try to get this to fit on one tape.
I would start by running RTVDSKINF.
Once that is done try PRTDSKINF *SYS and see where a bulk of the space it
tied up and then address that. Once you get the 30,000' view then you can
drill down further.
Is it "User Libraries"?
Is it "User directories"?
Is it elsewhere?
If "User libraries" then run
PRTDSKINF RPTTYPE(*LIB) to get a list of your biggest libraries. You can
drill down into that a little by
PRTDSKINF RPTTYPE(*LIB) OBJ(*ALL) MINSIZE(99999)
I've also found WRKJRNRCV JRNRCV(*ALL/*ALL) can be beneficial. Querying
DSPFD (if you had a newer OS I would recommend just querying
SYSPARTITIONSTAT) and RGZPFM those with a lot of deleted records.
If "User directories" make sure you didn't turn on some Management Central
tracing at some time. I've seen this take 30% of a system. This is
/QIBM/UserData/OS400/MGTC/service. If you're not tracing it should be
empty. If it isn't then turn the tracing off and clear it.
IBM has a RTVDIRINF and a PRTDIRINF but it doesn't have near the drill
down capabilities that PRTDSKINF has. No sort by size and whatnot.
