Chris,

I may have stated the information incorrectly. Of the 22 drives, 6 
are being utilized at 50-70% while the other 16 are averaging 5%. 
These disk store nothing but Domino and the entire box runs nothing 
but Domino.

Correct me if I'm wrong, but i5/OS doesn't create data like that. I 
would 
be REALLY curious to see how this person determined that ALL of the 
Domino 
data was only on 1/4 of the disks. Are those disks separated in a user 
ASP? That could be possible, but you would have had to poing the 
/LOTUS/DATA directory to that user ASP...

How much cache is on the controller that controls the drives on the 
iSeries
box that hosts Domino?  Domino seems to really perform better with a 
hefty
amount of disk controller cache.

Of course that doesn't explain why things were fine, then got bad. I'm 

not
sure what was the event that concentrated your Domino specific stuff 
on 
6
of the 22 drives... i'd have the guy who found that situation keep 
digging
further into it!  He should also be able to talk with IBM support for 
some
possible reasons why...

Hello Everyone,

I have been experiencing Lotus Notes performance issues since Monday
morning.  At first we thought the problem to be a run away process ( 
Router
task on a server was running at 80-90% for about 35min and it wasn't 
doing
anything ).  Since then ( Monday at 10:35am ), CPU for the entire LPAR 

has
been averaging 30% and peaking at 65%.  Still, as of the time of this
email, we are seeing intermittent performance issues. And by that I 
mean,
everything seems to run normally then for some seemingly random 
reason, 
it
take upwards of 4 minutes just to open an email that does not have an
attachment or switch to a different folder view, etc.  We sniffed the
network and found no network issues occurring during these moments 
that
Lotus Notes runs slow.  These moments tend to last about 5-10 minutes 
and
all goes back to normal.  The performance problems to not seem to tie 
into
any server task or event taking place.

After eliminating CPU we checked Memory.  The iSeries guru at our
organization informed me that there didn't appear to be any memory 
issues
but did notice that 6 of our disks ( of 22 ) were being hit hard. When 

he
did some further digging he noticed that ALL of the data for all 10 
server
instances on our LPAR were all on 6 of the 22 disks that we have. This 

was
not the case last week.  It would seem that the performance issues 
were
related to disk and he is performing a task to evenly distribute the 
data
among the 22 disks by usage.  Now you are all probably wondering, "How 

did
all the data end up on just 6 disks when it was spread across 22 last
week?"......  That, my friends, is the $100,000 question.  If anyone 
has
any ideas I would love to hear them.  Some background info.

Saturday night we applied PTF's to the LPAR.
We also ran Fixup on 3 of our server, and Updall -r  on 2 of the 3 
servers
that Fixup was run on.

That is the extent of the changes that occurred this weekend.  I have 
a
directors meeting in the morning at which they will be asking me why 
Lotus
Notes is running slow.  I believe I have determined what was the 
problem
but not the root cause.  If anyone can send me idea before 9am 
tomorrow.
Feel free to ask me any questions, I will provide as much detail as I 
can.

Thanks,
