/ACCESSED=n

    Specifies, for ODS-1 disk volumes, the approximate number of
    directories that will be in use concurrently on the volume. (The
    /ACCESSED qualifier is meaningless for ODS-2 volumes.)

    Specify a value from 0 to 255 to override the default that was
    specified when the volume was initialized.

    You need the user privilege OPER to use /ACCESSED.

    Example

    The following command requests the volume labeled WORK to
    be mounted on DKA1, specifying 150 as the number of active
    directories on the volume:

    $ MOUNT/ACCESSED=150 DKA1 WORK
