VMS Help SET, DEVICE, Qualifiers, /ERROR_LOGGING  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /ERROR_LOGGING
       /NOERROR_LOGGING

    Controls whether device errors are logged in the error log file.
    When you specify the /ERROR_LOGGING qualifier, all error messages
    reported by the device on which error logging is enabled are
    recorded in the error log file. Use the SHOW DEVICE/FULL command
    to find out the current status.
