Just curious if you don't mind please. We're using only a few percent of the Flash Memory, so I see no reason paging should go to AUX. Then, it is documented that VIO pages will never be paged to Flash. > Do you want 'snapshot' (with RMF II), interactive monitoring Starting at an interval which shows 30% local page DS being used, I'd like to find the address space(s), to which thsose pages belong. -- Peter Hunkeler -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

The JSTOR view doesn't tell which AUX slots are Flash and which are page DS slots. It's the sum of both. To my surprise, I can't see any job using VIO AUX slots. My previous assumption was wrong, it seems. What are reasons for SRM/AUX to page out to DASD instead of Flash, when Flash usage is low (below 10%)? I guess, none,are there? So, my current assumption is that we have had some peak on storage usage some time back which caused massive page out to Flash which also caused migration from Flash to AUX. Does this sound reasonable? --Peter Hunkeler -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
