COF102I COFVLFxx, VLF IS UNABLE TO DETERMINE THE VOLUME SERIAL FOR ANY ELIGIBLE DATA SET IN CLASS clsname.
Explanation
During virtual lookaside facility (VLF) initialization or modification, the system tried to get volume serial numbers from the catalog. In the COFVLFxx parmlib member, all data set names for a class were specified with EDSN keywords, but with no VOL keywords.
- xx
- The suffix of the COFVLFxx parmlib member where the class definition ended. Note that the CLASS statement could be in the parmlib member shown in this message or in a previous COFVLFxx parmlib member when there is a concatenation of members.
- clsname
- The class containing the data sets names.
System action
VLF initialization or modification continues; however, the class is not included in the table of valid classes. If there is no valid class statement in COFVLFxx, for a Start command VLF initialization ends after reading that member, for a Modify command the VLF configuration is not replaced. The system issues message COF015I.
Operator response
Notify the system programmer.
System programmer response
- Correct the syntax in COFVLFxx.
- Catalog the data set or sets in the class.
- Take corrective action according to the return code and reason code returned by the LOCATE macro. These codes are displayed in message COF015I, and are described in z/OS DFSMS Managing Catalogs.
