MOUNT
Sends a request to the system to reserve a volume set (keep it online).
The set must be online in order to have the command take effect. (Native
Mode)
Syntax
[{* }]
MOUNT [{ }] [.groupname[.acctname]] [;GEN=[genindex]]
[{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.
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
ignores the generation when attempting to satisfy
the MOUNT request.
Operation Notes
The MOUNT command reserves a specific volume set for use. It notifies
the system that the volume set is to remain online and is not to be taken
offline by a VSCLOSE command.
Volume sets in MPE/iX are not tied to groups and accounts. This is
different from the MPE V/E scheme of disk partitioning.
The MPE/iX naming convention for volume sets differs from the MPE V/E
naming convention for 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.
Table 2-20 illustrates the differences between the MPE/iX and
MPE V/E naming conventions for volume sets.

-----------------------------------------------------------------------------------------------
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 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/iX accepts the
naming convention that was used for MPE V/E private volumes. Thus MOUNT
V.G.A succeeds and MOUNT 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 all 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.
Various user commands that give you
access to your logon group's home volume set implicitly initiate
reservation requests if the volume set is not reserved already. An
example of one of these commands (BUILD) is:
BUILD VFILE;DISC=500,10,1;REC=-80;DEV=VCLASS1
To issue a reserve request programmatically, you may issue an FOPEN call
referencing a file residing on an unreserved volume set; this causes an
implicit user initiated reserve request. An FOPEN reserve remains in
effect until a corresponding FCLOSE intrinsic call is issued. The
programmatic request is used when a single job/session step requires a
certain volume set. Refer to the MPE/iX Intrinsics Reference Manual
(32650-90028) for a description of a programmatic reserve request.
It is recommended that you not use the MPE V/E naming convention and
xxxMOUNT commands. Instead use the MPE/iX naming convention and 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. Use volumes (UV) or create
volumes (CV) capability is required to use this command.
Examples
You are logged on to account MYACCT in group GRP. To request the system
operator to reserve volume set MYSET in that group and account, with a
generation index of 43, enter:
MOUNT MYSET;GEN=43
If you are logged on in another group.account, enter:
MOUNT MYSET.GRP.MYACCT;GEN=43
