Library /sys$common/syshlp/sysmanhelp.hlb DO, Qualifier, /OUTPUT  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /OUTPUT[=filespec]

    Records output from the command in the specified file, which
    is located on the node from which you are executing SYSMAN.
    Position the qualifier immediately after the DO command. The
    default file specification is SYSMAN.LIS in the current device
    and directory. SYSMAN prefaces output with the message "%SYSMAN-
    I-OUTPUT, command execution on node xxxxxx."
