Re: [Junk released by Allow List] Interesting Disk UNIT 1 behavior

Are we saying that more than just the base LIC is on unit 1?

If it is QSYS, then there are journal receivers for auditing, history
log files, etc...

I guess what catches me a little off guard is I would expect read
activity, it's the write requests that have me a little confused. I
guess the OS overrides the stop allocation on the load source.

I'm not an expert like you and others, but, since the Load Source is
on Drive 1, doesn't that mean that most of the system "stuff"
including MI is there? If so, wouldn't this account for the higher
percentage? If not, hmmmm here, too.

Discussion Subject: [Junk released by Allow List] Interesting Disk
UNIT 1 behavior Some time back I heard/read/was told that for best
performance the first disk unit in the system ASP (The Load Source)
should be flagged for End Allocation and user data removed from it
with STRASPBAL. So I did this on Frankie just to see if I could notice
anything. This has been this way for many months. Today I happened to
have WRKDSKSTS up and saw this: ================= Elapsed time:
