IGD17283I

Explanation
Explanation: The no-convert interface is a special
interface, used primarily by DFDSS that requires that the track size
of the selected volume be equal to or greater than the track size
specified on the allocation request. All Storage Groups that do not
meet this criteria are rejected and the allocation continues with
any other Storage Groups that may have been selected. If there are
no other Storage Groups, the allocation fails.

System action
The SMS VTOC Data Set Services request fails.

Programmer response
Correcting this situation may require that
the ACS routines be modified to select an appropriate Storage Group,
in other words, one that meets the track size criterion.
