This already implies that one should not interfere with this presumption by ASM
by placing other datasets with (heavy) load on the same volume. ASM assumes 2
private paths and if WLM does not assign more aliasses, the non-paging I/O will
influence the paging I/O negatively.
I agree with that. It makes no sense to put heavily-used datasets on
the same volume as paging datasets. But lightly used datasets should
not be a problem, with the caveat that even a "lightly-used" dataset can
be heavily used in short bursts.
I have found more than one customer who has placed shared datasets
subject to RESERVE, such as catalogs, on th same volume as paging
datasets. That is just foolish!
