Not site specific... SMS specific

all the SMS managed datasets must be cataloged

Hi,

NO SMS managed dataset can be uncataloged

Then we can try to allocate the DSN on non-SMS volume & delete it from SMS volume.

I think an ACS routine can override the storage class that you specify on the STORCLAS parameter. Per manuals (QW) STORCLAS can be omitted even if SMS is active if an Automatic Class Selection (ACS) SMS exit is in use at your site.

Please check the last 5-6 posts from this thread, they tell how can one overide or place a DSN on a NON-SMS volume.

I tried it, ah.. I'm not a storage guy, hard time in getting volume-serials numbers of non-SMS vloumes ( if any at my site). By the time you can give a try, might help.

lol give it up everybody.. I'm destined to wake up @ 3AM and move it while CICS regions are down. It's a lot easier.

Can you not leave (or get scheduled) a job to perform the library renames as soon as CICS comes down ?

I'm as confused as you, heck I can't even spell ACS, let alone what to do with it....
Just to say, that after I started working in an SMS environment, there had always been a way to assign an allocation to a non SMS volume, it was limited and it did not last long (not even overnight usually), but it could be done.......

I'm not.. icon_razz.gif , well, I just can't try it that fast as a system/storage guy could..

Some shops implement this by code in the ACS routine like this:
Code:
IF &STORCLASS='NONSMS' THEN SET STORCLAS=''

But then there are other ways that the ACS routines can have a
Code:
THEN SET STORCLAS=''

e.g. it may just be coded that if you specify a certain (NONSMS) volser in your JCL then the ACS code will "honour" the allocation.
Code:
IF &ANYVOL='SYS%%%' THEN SET STORCLAS=''


Again, I'm not a storage guy, but an application engineer (only 'they' say, I still feel I'm quite dum*.. icon_smile.gif ) all above written I know because manual says so & perhaps it's been posted in this forum as well. I never tried it but one in need can..

BTW, he already decided something ..
