I just posted these to the System i Network forums that might be of
interest regarding disk space (you are likely aware of these but just in
case)
Check for journal receivers, if there are a lot of "old" ones on your
system, back them up to tape and delete them. those can take up TONS of
disk space.

Check the number of spooled files on the system, if you have lots of old
spooled files hanging around, back them off to tape & delete them (actual
spooled file data is stored in files in the QSPL library)
any save files that are old/unused, back up to tape & remove.

if you have lots of temp applied PTFs (note this is not my preference but
is an option) perm apply those PTFs and schedule an IPL that will remove
the PTF save files.

Check the IFS for unused/old files, if possible back up to tape & delete.
lots of times the IFS is the "forgotten" realm that will eat up disk space
BIG time.

Check for files with lots of deleted records, reorg those files to
compress out those records, even if they are "deleted" the disk space is
still reserved for those records.

Thanks,
Tommy Holden

You could gain some space by applying all PTFs permanently.

I know you know this stuff, but some thoughts -

Do you know what is taking all the space? Is it all valid? You might not
have enough space to run RTVDSKINF, if so, try DSPOBJD *ALL/*ALL *ALL to
*PRINT - for IFS, try opening a netserver share to root and run a
recursive dir from a command prompt, redirected to a file on the PC.
That'd take care of the DSPOBJD, too, I think, if even THAT would take
too much space. Although 80% shouldn't kill you on any of these, even
RTVDSKINF.

Is there anything you can archive to tape?

Look for lots of spooled files.

Look for journal receivers.

Do you have a web server running from this machine? Look for logs and
change settings to keep only the last 7 days.

Jerry,

Put the cursor in that column& hit F1 for help on the different
possible
statuses.

I'd love to, but we're so scrunched for space (running at about 80%
used)
that I elected to *not* install on-line help. In fact, I'm going to
remove
some stuff (such as Advanced Job Scheduler which we don't use anyway),
but
install a couple of things I *want* (Openness Includes and QShell).
Hopefully the deletions will balanced out the additions. If not QShell
will
be the first to go.

Just found the problem analysis, repair, and parts manual for your 250:

Thanks.

I found the System Builder manual. I'm probably mis-reading, but it
looks
like the 2748/2763 are only required if more than 4 disk units are
installed
(expansion unit? We don't have one) or RAID-5 is required. The 675A
is a
MFIOP. I'll admit I'm not sure what the manual means here: "The MFIOP
(CCIN
675A) and the processor are combined together on the planar board. It
also
includes embedded base disk unit controller. A separate #9728 is not
required. The #2407 includes a #9740 Base RAID Disk Unit Controller.
The
MFIOP drives two low-speed slots C08, C09, and two high-speed PCI slots
C03
and C07. It supports #2740/#9740, #2741 or #2748 PCI RAID Disk Unit
Controllers only, if there are more than four disk drives, and RAID-5
is
required." Except the part about " also includes embedded base disk
unit
controller".

Anyway, nice to know that, when things degrade to a snail's pace, I can
use
WRKDSKSTS to see something.

2748 disk controllers have 26MB of cache. 2763 controllers have 10MB.
Those are the two controllers I see for Model 250 systems in the System
Builder I have from that era. WRKHDWRSC *STG should show you which
controller you have.

Also, most if not all of the time you can see if the cache batteries
are
still good by doing a WRKDSKSTS followed by F11. The Status column
normally
shows "DEGRADED" if the cache batteries have failed and the write cache
is
disabled. This doesn't let you predict or anticipate battery failure
like
the service tools function, but it does let you confirm that the cache
memory is in fact being used (which it only does if the batteries are
good).

Boy, Rob, I never would of thought of going that route. But it did, I

list
that remotely looked like it had anything to do with batteries (and I

batteries
in
the 250.

As far as the "old" part goes, I figured that. I still have to
maintain
my
previous employer's software and run functions for the auditors (even
after
you close the doors, they're still there!) so I compare things
whenever
I
have a chance, and STRSST menus are different. I'm pretty sure I'll
have
to
live with the old (V5R1 and Model 250) for awhile (sigh).

Good advice. Had a cache battery die on a Model 720 and it took me
all
day
to figure out why things had ground to a snail's pace. The Model 520
actually gave out a shout when it wanted its diaper changed.

The new employer has a Model 250 (running V5R1). I don't know if it
has
a
cache battery or not (though I suspect that it does). SST doesn't
show
an
option '9' and I couldn't find anything about cache batteries in any
of
the
other options, though I could have missed it or misinterpreted it.

Seems I'm wrong guessing that there is cache on the 250. The System
Handbook shows 0 for L2 Cache. But, then, the Handbook only shows
6818
model disk units (17.54 gig) whereas ours has 6717 units (8+ gig).

I strongly suggest checking your cache batteries on a regular basis
and
when the time to warning gets down to 45 days or so, calling IBM and
ordering it then. Mine have been backordered a while and I am still
waiting on a replacement.

Apparently some batteries are harder to get ahold of than others. At
