Qualifiers

/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


/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   is no longer valid.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.


/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.


/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.


/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.


/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.


/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.


/WRITERS
      /WRITERS
      /NOWRITERS (default)

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