1    /CLASS

       /CLASS=className

    Specifies a subset of the complete LASTport Disk (LAD) name
    space.

    The purpose of class names is to subdivide name spaces so that
    clients see only those names that are meaningful to them. The use
    of class names also allows two services to have the same name and
    not conflict with one another.

    You can, for example, use different class names for different
    on-disk structures that several client systems use. You
    might use SERVICEA/CLASS=ODS-2 for some client systems and
    SERVICEA/CLASS=ISO_9660 for other client systems. The service
    has the same name, SERVICEA, but the class names are different.

    The class name you use depends upon the client systems that will
    connect to the service being created. The default class name
    is ODS_2. For example, OpenVMS systems use the ODS_2 name space
    when attempting to mount an InfoServer device. Note that OpenVMS
    clients can solicit only those services that are in the ODS_2
    service class.

    Valid class names are the following:

               V2.0           Names understood by PCSA MS-DOS Clients
               Unformatted    Virtual disk has no format
               MSDOS          MSDOS virtual disks
               ODS_2          VMS virtual disks
               UNIX           UNIX virtual disks
               ISO_9660       ISO 9660 CD format
               HIGH_SIERRA    MS-DOS CD format
               APPLE          Macintosh HFS format
               SUN            Sun format

2    /ENCODED_PASSWORD

       /ENCODED_PASSWORD=hexstring

    The SAVE command creates this qualifier. Because passwords are
    not stored in plain text, the hashed password value is written
    out as part of the SAVE operation so that the service can be
    recreated without revealing the password.

    Note that if you edit the command procedure that the SAVE command
    creates and change the service name, the encoded password value
    is no longer valid. You need to set another password on the
    service using the /PASSWORD qualifer.

3    /PASSWORD

       /PASSWORD=passwordString
       /NOPASSWORD (default)

    Specifies an optional access control password for the service.
    The client system must specify the password to access the
    service.

    The password string can be up to and including 39 alphanumeric
    ASCII characters in length. If no password is specified, the
    client system is not required to provide a password to access the
    service.

    The text password is hashed and stored in encrypted form in
    memory with the other service information.

4    /RATING

       /RATING=DYNAMIC
       /RATING=STATIC=value

    Clients use the service rating to select a service in the case of
    multiple matching services. The service with the highest service
    rating is selected.

    The system adjusts the dynamic service rating based on load. You
    can also set a static rating between 0 and 65535. The system does
    not adjust static ratings.

    One use of static ratings is to migrate clients from one copy
    of a service to another. If you set a static rating of 0 on
    services you want to migrate clients away from, no new clients
    will connect to a 0-rated service; instead, they will connect to
    higher-rated services. When all current clients have disconnected
    from a service, you can safely delete it.

5    /READAHEAD

       /READAHEAD (Default)
       /NOREADAHEAD

    When a disk read is required to fill a cache block, /READAHEAD
    specifies that the read is to be from the first block requested
    to the end of the bucket boundary. Readahead can speed up
    sequential operations by pre-loading disk blocks that are needed
    into the cache.

    If you specify both /READAHEAD and /READBEHIND, any block
    requested within a cache bucket causes the entire bucket range
    of blocks to be read into the cache.

6    /READBEHIND

       /READBEHIND
       /NOREADBEHIND (default)

    When a disk read is required to fill a cache block, /READBEHIND
    specifies that the read is to include all blocks from the
    beginning of the cache bucket boundary up to and including the
    requested blocks.

    If you specify both /READAHEAD and /READBEHIND, any block
    requested within a cache bucket causes the entire bucket range
    of blocks to be read into the cache.

7    /READERS

       /READERS=number (default READERS 1000)
       /NOREADERS

    Specifies the maximum number of simultaneous client connections
    allowed for read access. The default is 1000 readers. A value of
    0 indicates write-only access.

    If a client requests read-only or read/write access to a service,
    the system counts this as one reader.

8    /WRITERS

       /WRITERS
       /NOWRITERS (default)

    Specifies that the service is to allow access to a single writer.
