Re: Equipment question -- MIDRANGE-L



Load source drive (1) is where microcode, boot code, etc. go (and
originally system dump space - until the memory capacities started growing
larger than some disk drives) so now system data will spread over to other
drives.
If the first drive was large enough it was not "reserved" for system usage
- user data can also reside there.
You could easily have more than 1.9GB "system" data on V4 releases, so
you're seeing that first drive full.
You didn't show a display after a minute or so on a busy period (elapsed
time was 00:00) so can't see what & Busy you're experiencing.  You could
slap a couple of used 6606's in base system (mirrored) fairly cheaply - to
reduce the load on the unit 1 pair - but whether or not you need to depends
on how busy they are.

One drive being full isn't really a concern (unless it's a separate ASP).
The 400 will happily manage things (issuing warnings every hour if you
exceed the ASP threshold percentage set in SST) until the total usage hits
99.9999% - then it will IPL.  With newer releases you can set your own
thresholds & actions for disk filling up via the QSTGLOWACN & QSTGLOWLMT
system values.

Subject:  Equipment question





I have a question about the 9402 Model 400 - 2132 system processor & 128MB
of memory we have.  Doing a WRKDSKSTS this morning, I noticed the
following:

The 6606 drives are mirrored and the 6607's are running Raid-5.  This is
the
test/dev box and I am aware of the performance problem we will have with
the
6607 drives being as full as they are and that is okay for being a test/dev
machine.  What has me concerned is the 6606 drives being as full as they
are.  Before I deleted the PM/400 performance files and then an IPL this
morning, the percent used was ++++++.  Someplace I remember hearing/reading
that the 6606 drives were reserved for "system programs".
Monday morning the percent used was 91.7%.  Since then I have restored a
library twice - our main BPCS files library.  I don't know what to do
AND/OR
if it is even a problem.  My gut says it is a problem whenever a drive
becomes full.  Doing a RCLSTG vs. an IPL was discussed in this list
recently
and an IPL was going to get about the same results was what I vaguely
remember from that thread.
What do I do?
