Allocating non-SMS managed dataset using SMS-managed volume

Hi,

Can I allocate a non-SMS managed dataset using a SMS-managed volume? That is, in VOL=SER can we specify a VOLSER which is SMS managed.

Do I need to change anything in the following jcl to do the allocation?

//NONSMS DD DSN=MY.NON-SMS,
// DISP=(NEW,CATLG),
// UNIT=3390,
// VOL=SER=SMS-MANAGED,
// SPACE=(CYL,(00001,1,1))

Currently we are using non-SMS managed datasets and we don't have any SMS managed volume. So I'm not able to verify this case.

Please let me know if this is possible or not?

Short Answer = NO, you cannot allocate a NONSMS dataset on an SMS volume. Period.

Only SMS managed datasets, i.e. those assigned a Storclas by the SMS ACS Storclas routine are SMS managed. And even then the Storgrp ACS routine has to assign them to an SMS Storgrp with some ENABLED or QUINEW volumes in it, that are initialised by ICKDSF as SMS format (using the STORGRP parameter) before you can allocate on an SMS volume. There is virtually no way to circumvent this, that I would tell you about.

PS: Even if you code VOL=SER=volser in your JCL, but the dataset is eligible to be SMS managed the volser will be ignored, and SMS will decide on the volume to be selected.
