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.
* orSpecifies 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
