Lock=lock-list

    Displays information for each of the specified locks. When
    combined with the Mode=Blocking qualifier, the Lock qualifier
    displays information about processes whose locks are blocking the
    specified locks. When combined with the Mode=Waiting qualifier,
    the Lock qualifier displays information about processes whose
    lock requests are waiting for the specified locks.

    by commas. The lock identifier is an 8-digit hexadecimal number,
    and must be local to the node on which the RMU Show Locks command
    is issued. To see the lock identifier upon which a process is
    waiting, you can do either of the following:
