If you have the deprecated syntax in your data set separation profile, consider updating the profile to use the current syntax. Toleration PTFs are available that provide support for the z/OS® V1R11 syntax for PCU-level separation on lower level systems, with the exception of wildcard characters in data set names. With the PTFs, separation groups defined with syntax that is not supported, such as SEP(VOL) or wildcard characters in the data set name list, are ignored.
