A z/OS® UNIX file system or a VM/ESA Byte File System (BFS) could not be mounted during dynamic allocation. The dynamic allocation reason code returned in errno2 is documented in z/OS MVS Programming: Authorized Assembler Services Guide or VM/ESA Application Development Guide: Authorized Assembler Language Programs. This message is equivalent to the errno, EMVSDYNALC.
The request fails. The application continues to run.
Have the system programmer correct the allocation of the z/OS UNIX file system data set or VM/ESA BFS.
