Command Definition F-K
LDISMOUNT
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
*.grp.acct. The home volume set of the group grp in
account acct.
Causes an error.
myset_grp_acct Error (name component longer than eight
characters).
The volume set named
myset_grp_acct.
m_g_a The volume set named
m_g_a.logongrp.logonacct, provided it
exists. If it does not exist, an error is
reported.
The volume set name m.g.a.
