This message indicates that an uncorrectable VSAM error occurred. The name of the file is displayed along with the error code, which appears in both decimal (nnn) and hexadecimal (xx) formats. One of four possible types of VSAM errors are possible:
1. GENCB indicates an error occurred while building or modifying a VSAM control block.
2. OPEN indicates an error occurred while attempting to open the specified file.
3. LOGICAL indicates that an illogical I/O request was made (such as a random keyed access to an ESDS).
4. PHYSICAL indicates that a physical I/O error occurred for the specified file.
These error codes "nnn(xx)" are described in the IBM VSE/VSAM Messages and Codes Manual.
