     Requests a logical reservation of a volume set. This informs the
     system that the volume set is to be reserved system-wide.  The
     corresponding new command is VSRESERVESYS.


            {*            }
     LMOUNT[{             }][.groupname[.acctname]][;GEN=[genindex]]


For the commands MOUNT, DISMOUNT, LDISMOUNT, and LMOUNT, a volume
set name such as V.G.A can have no more than eight characters in any
part of the name.  If the length of V, G, or A exceeds eight
characters, an error is reported.


* or <blank>        Specifies the home volume set for the group and
                    account specified, or for the logon group and
                    account if groupname or groupname.acctname is not

volumesetname       An artificial component of a volume set name used
                    to maintain backward compatibility with MPE V/E.

groupname           Used only for compatibility with MPE V/E.

acctname            Used only for compatibility with MPE V/E.

genindex            A value from -1 to 32,767 specifying which
                    generation of the home volume set is to be reserved.
                    A value of -1 indicates that any generation is
                    permitted. If omitted, the system will ignore the
                    generation when attempting to satisfy the MOUNT


     When the console operator executes this command, all disk drives
     containing members of the specified volume set become RESERVED.
     Each volume set is logically attached to the drive until an
     LDISMOUNT command is executed, at which time the disk drive is no
     longer reserved on a system-wide basis.  A VSCLOSE may then be
     issued to remove the volume set (Refer to the VSCLOSE command).

     Executing an LMOUNT command does not prevent users from issuing a
     MOUNT command for the volume set in question.  Users may issue a
     DISMOUNT command for the specified volume set, but doing so will
     have no effect; the LMOUNT command takes priority over a general
     user command.

     System users issue mount requests implicitly through their
     programs, or explicitly with a MOUNT command.

     If the Mountable Volumes Facility was enabled with VMOUNT ON,
     AUTO, MPE/iX will automatically attempt to satisfy the mount
     request; the LMOUNT will succeed if the specified volume set is
     physically connected to the system.

     If the Mountable Volumes Facility was enabled with VMOUNT ON
     (omitting the AUTO parameter), you must reply to your own mount
     request, even though the volume set may already be mounted and in

     Volume sets in MPE/iX are not tied to groups and accounts (this
     differs from the MPE V/E scheme of disk partitioning).

     MPE/iX uses a new naming convention for volume sets.  MPE/iX
     volume set names may consist of any combination of alphanumeric
     characters, including the underbar (_) and the period (.).  The
     name must begin with an alphabetic character and consist of no more
     than 32 characters.

     In MPE V/E, the name V.G.A indicates that V names a volume set,
     that G is the name of a group, and that A is the name of an

     MPE/iX will accept that name in that form, but no interpretation
     is made as to the referencing of G and A. Instead, MPE/iX treats
     V.G.A as a single, long string name, just as it would treat

     As a convenience to established Hewlett-Packard users, MPE/iX
     will, however, accept the naming convention that was used for
     MPE V/E private volumes.  Thus MOUNT V.G.A will succeed.  And
     MOUNT V will access the same volume set, provided you are logged
     on onto account A, group G.  The older commands are able to
     "default" the logon account and group.

     However, VSRESERVE V will succeed only if there is a volume set
     V in existence.  The new commands will not call up any default
     specifications for group and account.  VSRESERVE V.G.A will
     succeed only if a volume set V.G.A is on line. With all new
     VSxxxxx commands, the .G.A component of this name is interpreted
     as a string, neither more nor less specific than _G _A.

     Be aware, though, that if a volume set is named according to the
     old MPE V/E naming convention (V.G.A), then you must use an
     unambiguous reference when using the MPE/iX volume set commands.

     It is strongly recommended that you avoid using the MPE V/E
     naming convention and the xxMOUNT commands.  Instead use the
     MPE/iX naming convention and the new VSxxxxxx commands.
     Alternating old and new commands may lead to confusion and in some
     cases may lead you into time consuming errors.  For example,
     MOUNT X used in a job stream will attempt to access a volume set
     named X.logongrp.logonacct -- which may or may not be your

     This command may be issued from a session, job, program, or
     in BREAK. Pressing [Break] has no effect on this command.  It
     is executable only at the console unless it is distributed to
     users with the ALLOW command.


     To reserve a volume set named DATABASE.PAYROLL.ACCTNG, enter


     You may, as an alternative, use the new VSRESERVESYS command
