DFSMS/DASD: Control SG occupancy

[af dc]

Hello,
can anyone give me an hint about how to control SG occupancy, like, hourly
have a msg to syslog with a list of selected SGs with 75% of occupancy. I
have a request to monitor a  SG where after getting 70% of occupancy an
alert must be issued to us (storage administrators). Can this be done ??

Any hint, sugestion is welcome.
Many thx, Antonio Cecilio.

>From straight ISMF or DFSMS probably not because I think you will need
something that creates the alert and send it to you.

However with tools like Tivoli Omegamon, CA-SYSVIEW, CA-Vantage, CA-GMI, IBM
RMF, or other like tools, probably.

Or if you have CA-PDSMAN, VTOC Tool from CBT TAPE, you could have jobs that
run hourly that you program your process to do the alerting.

We have hi and lo water marks set in certain pools in DFSMS and then use
OPS/MVS to capture any IGD17380I message to send our storage group an alert.

[Staller, Allan]

Use DFSHM interval migration to maintain the SG at the appropriate
occupancy levels.  
Migration will wake up every X minutes (hours?) and migrate data until
the appropriate thresholds are reached.

I haven't had the need to do this myself, so you will need check the
fine manuals for details.

Do not forget that most scheduler's have a way to trigger jobs by 
messages. You could have your scheduler trigger a email job if you have 
email or at least send a message to the console saying to call one of the 
storage group folks.

Re: DFSMS/DASD: Control SG occupancy

[Joel C. Ewing]

But note that interval migration will only migrate data that is eligible 
for migration (by management class and last referenced date), so there 
is no guarantee that it can maintain the requested usage levels, 
especially in a shop with wide variation in workload or with long-term 
growth.  There is still a need to monitor by other means.

Re: DFSMS/DASD: Control SG occupancy

[af dc]

Thx to all your replies.
The issue here is not about the automation, is how to create the msg to
syslog. I was thinking of something like (rexx, report, tool, etc) where I
could get ISMF/SG %FREE SPACE or MXI SGRP %use values (these are examples).

It's seems that it's not straight forward.

[Staller, Allan]

If the pool is maintained continuously at/near the required level, why
is it necessary to generate a message at all?

Hi Allan,
msg generation it's a hint, I was thinking of some tool to send a msg on
syslog and automation picks it and do whatever we wanted, But if there's a
way to do it all, great..

I'm not at ease with NAVIQUEST, do you know if it can do it??

[Scott Rowe]

SMS will issue message IGD17380I when the high allocation threshold is
exceeded - does this not meet your needs?

Re: DFSMS/DASD: Control SG occupancy

[Staller, Allan]

This is a built-in function of DFHSM. NAVIQUEST is not even needed.
Disclaimer: I have almost zero exposure to NAVIQUEST.

Check the parameter SETSYS INTERVALMIGRATION in the DFHSM Reference or
the topic INTERVAL MIGRATION in the DFHSM Guide.

Re: DFSMS/DASD: Control SG occupancy

[C. Ardillo]

I'm just an application programmer but from my tool set I'd run an 
idcams dcollect job against the storage groups in question then use 
something like easytrieve to compute my thresholds and send an email if 
needed from same job.

Antonio - if you have the Quickref product, you can (or I can supply) a REXX 
exec that checks the percentages of a storage group from a batch job that 
runs periodically, and you can use SMTP to email you an alert (if you have 
SMTP set up).  You would have to have a scheduling package to run the job 
whenever you would like as well.

Patrick,

If you don't mind, I would be interested in the REXX code.  Can you post it or 
email it to me directly?  I'd really appreciate it.

Thanks

Re: DFSMS/DASD: Control SG occupancy

[Kenneth J. Kripke]

Another method will require some parsing of an IDCAMS DCOLLECT report output, 
but, you can gather
data by Storage Group using it and tabulate utilization figures.  You would 
probably have to schedule a batch job via your job scheduler for some interval 
value or whatever.

[Gonzalo Cengotita]

Hello,

You can find an example of using ISMF in batch here:

http://www.servframe.com/jcl-samples/

There is an example called "Generate an ISMF storage group list in batch"

This list have a field with the "% free" value that you can read with a REXX
and compare with the values you consider appropiate and send a message,
email, (or whatever you want).



Regards,
Gonzalo Cengotita
