       /PROTECTION=keyword

    Specifies the protection code to be assigned to the volume.

    The following table describes the keywords for this qualifier:

    Keyword       Description

    protection    Specifies the protection code according to
    code          the standard syntax rules for specifying user
                  protection (that is, system/owner/group/world).
                  If you omit a protection category, that category of
                  user is denied all access.

                  If you do not specify a protection code, the
                  default is the protection that was assigned to
                  the volume when it was initialized.

    XAR           Enables enforcement of the extended record
                  attribute (XAR) access controls. For more
                  information about XAR, refer to the OpenVMS Record
                  Management Services Reference Manual.

    DSI           Enables XAR permissions Owner and Group for XARs
                  containing Digital System Identifiers (DSI). For
                  more information, refer to the OpenVMS Record
                  Management Services Reference Manual.

    If you specify the /PROTECTION qualifier when you mount a volume
    with the /SYSTEM or /GROUP qualifier, the specified protection
    code overrides any access rights implied by the other qualifiers.

    If you specify the /FOREIGN qualifier, the execute (E) or create
    (C) and delete (D) access codes are synonyms for logical I/O (L)
    and physical I/O (P). You can, however, specify the access codes
    physical I/O (P) or logical I/O (L), or both, to restrict the
    nature of input/output operations that different user categories
    can perform.

    To use the /PROTECTION qualifier on a Files-11 volume, you must
    have the user privilege VOLPRO or your UIC must match the UIC
    written on the volume.

    Example

    The following command mounts a device labeled WORKDISK on DKA1
    and assigns a protection code. Access to the volume will be read,
    write, and create for system users; read, write, create, and
    delete for owner; read and create for group users; and read-only
    for users in the world category.

    $ MOUNT/PROTECTION=(SYSTEM:RWE,O:RWED,G:RE,W:R) DKA1: WORKDISK
