Negates a previously issued LMOUNT or VSRESERVE command.
This informs the system that the volume set is no longer
reserved system-wide. The corresponding new command is


                {*            }
LDISMOUNT [{ BLANK }][,groupname[.acctname]]


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 specified.

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.


     LDISMOUNT negates a previously issued LMOUNT or VSRESERVE
command. It informs MPE/iX that the volume set is no longer
reserved system-wide.

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 account.

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 A_VERY_LONG_NAME_FOR_SOMETHING.

As a convenience to established Hewlett-Packard users, MPE
XL will, however, accept the naming convention that was used
for MPE V/E private volumes. Thus LDISMOUNT V.G.A will
succeed. And LDISMOUNT 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 volumeset 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

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 intention.

This command may be issued from a session, job, or in BREAK,
but not programmatically. Pressing [Break] has no effect on
this command. It may be executed only from the console unless
it is distributed to users with the ALLOW command.


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


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