CBR4190I LACS {MOUNT | DEMOUNT} unexpected error from library library-name, volume volser, job job-name, drive device-number, error code error-code, modifier modifier.
Explanation
A permanent error was detected during library automation communication services (LACS) processing for the MOUNT or DEMOUNT functions for job job-name on device device-number. Library library-name returned with a unit check and an unexpected error code error-code and modifier modifier. The volume volser information that is displayed is the requested or mounted volume serial number. For a nonspecific mount request (SCRTCH or PRIVAT), SCRTCH appears for the volume serial number.
System action
The permanent error return code is set, and control is returned to the caller. An SVC dump with a system abend code of 0B6-2C is also requested.
Operator response
For a mount request, retry the failing job.
System programmer response
Search problem reporting databases for a fix for the problem. If no fix exists, save the console log and the dump data set, and contact the IBM® Support Center with the unexpected error code and modifier documented in this message.
