Causes a volume set that was explicitly reserved by the user (with a MOUNT or VSRESERVE command) to be released. The corresponding new command is VSRELEASE.
{* } DISMOUNT[{ }][.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. This command may be issued from a session, job, or in BREAK. It may not be used from a program. Pressing [Break] has no effect on this command. You must have UV (Use Volumes) or CV (Create Volumes) capability to use this command.
The DISMOUNT command allows you to release a volume set that you explicitly reserved using the MOUNT or VSRESERVE command. You can request a release only for a volume set that you have reserved; you cannot alter the status of the volume set for other users. 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 HP users, MPE/iX will, however, accept the naming convention that was used for MPE V/E private volumes. Thus DISMOUNT V.G.A will succeed. And DISMOUNT 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, VSRELEASE 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. VSRELEASE 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.
To release the volume set MYSET.B.C, that you previously reserved with a MOUNT or VSRESERVE command, enter DISMOUNT MYSET.B.C You may, as an alternative, use the new VSRELEASE command VSRELEASE MYSET.B.C
