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
VSRELEASESYS.
{* }
LDISMOUNT [{ }][,groupname[.acctname]]
{volumesetname}
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
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 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
LDISMOUNT DATABASE.PAYROLL.ACCTNG
You may, as an alternative, use the new VSRELEASESYS
command
VSRELEASESYS DATABASE.PAYROLL.ACCTNG
