Library /sys$common/syshlp/nclhelp.hlb disable, osak  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Puts the OSAK entity in the NotAvailable state in which it does not
    accept any more inbound or outbound association requests, and
    existing associations are aborted.  If the OSAK entity is already in
    the NotAvailable state, the command has no effect.
