LDISMOUNT
Cancels a previously issued LMOUNT or VSRESERVE command. This informs
the system that the volume set is no longer reserved system-wide. The
equivalent native mode command is VSRELEASESYS. (Native Mode)
Syntax
[{* }]
LDISMOUNT [{ }][,groupname[.acctname]]
[{volumesetname}]
Parameters
* 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.
volume- setname An artificial component of a volume set name used
to maintain backward compatibility with MPE V/E.
The volumesetname can be a maximum of 8 characters.
groupname Used only for compatibility with MPE V/E. The
groupname can be a maximum of 8 characters.
acctname Used only for compatibility with MPE V/E. The
acctname can be a maximum of 8 characters.
Operation Notes
The LDISMOUNT command 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 is
different from the MPE V/E scheme of disk partitioning.
Table 2-16 is a comparison of naming conventions for MPE/iX volume sets
and MPE V/E private volumes. 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 is the name of a volume set,
that G is the name of a group, and that A is the name of an account.
MPE/iX accepts that name in that form, but no interpretation is made as
to the referencing of G and A. Instead, MPE/iX accepts that name in that
form, but no interpretation is made as to the referencing of G and A.
MPE/iX treats V.G.A. as a single, long string name, just as it would
treat A_VERY_LONG_NAME_FOR_SOMETHING.
MPE/iX does, however, accept the naming convention that was used for MPE
V/E private volumes. Therefore, LDISMOUNT V.G.A succeeds, and LDISMOUNT
V accesses the same volume set, provided you are logged on to account A,
group G. The MPE V/E commands are able to "default" the logon account and
group.
However, VSRESERVE V succeeds only if there is a volume set V in
existence. The MPE/iX commands do not call up any default specifications
for group and account. VSRESERVE V.G.A succeeds only if a volumeset
V.G.A is online. With MPE/iX VSxxxxxx commands, the .G.A component of
this name is interpreted as a string, neither more nor less specific than
_G _A.
If a volume set is named according to the MPE V/E naming convention
(V.G.A), you must use an unambiguous reference when using the MPE/iX
volume set commands.
It is recommended that you not use
the MPE V/E naming convention and the xxxMOUNT commands. Instead use the
MPE/iX naming convention and the VSxxxxxx commands. Alternating between
MPE V/E and MPE/iX commands may lead to errors. For example, MOUNT
X used in a job stream attempts to access a volume set named
X.logongrp.logonacct, which may or may not be your intention.
Use
This command may be issued from a session, job, program, or in BREAK.
Pressing Break has no effect on this command. It may be executed only
from the console unless distributed to users with the ALLOW command.
Examples
To release a volume set named DATABASE.PAYROLL.ACCTNG, enter:
LDISMOUNT DATABASE.PAYROLL.ACCTNG
You may also use the VSRELEASESYS command:
VSRELEASESYS DATABASE.PAYROLL.ACCTNG
