Requests a logical reservation of a volume set. This informs the system that the volume set is to be reserved system-wide. The corresponding new command is VSRESERVESYS.
{* } LMOUNT[{ }][.groupname[.acctname]][;GEN=[genindex]] {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. 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 will ignore the generation when attempting to satisfy the MOUNT request.
When the console operator executes this command, all disk drives containing members of the specified volume set become RESERVED. Each volume set is logically attached to the drive until an LDISMOUNT command is executed, at which time the disk drive is no longer reserved on a system-wide basis. A VSCLOSE may then be issued to remove the volume set (Refer to the VSCLOSE command). Executing an LMOUNT command does not prevent users from issuing a MOUNT command for the volume set in question. Users may issue a DISMOUNT command for the specified volume set, but doing so will have no effect; the LMOUNT command takes priority over a general user command. System users issue mount requests implicitly through their programs, or explicitly with a MOUNT command. If the Mountable Volumes Facility was enabled with VMOUNT ON, AUTO, MPE/iX will automatically attempt to satisfy the mount request; the LMOUNT will succeed if the specified volume set is physically connected to the system. If the Mountable Volumes Facility was enabled with VMOUNT ON (omitting the AUTO parameter), you must reply to your own mount request, even though the volume set may already be mounted and in use. 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/iX will, however, accept the naming convention that was used for MPE V/E private volumes. Thus MOUNT V.G.A will succeed. And MOUNT 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 volume set 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, program, or in BREAK. Pressing [Break] has no effect on this command. It is executable only at the console unless it is distributed to users with the ALLOW command.
To reserve a volume set named DATABASE.PAYROLL.ACCTNG, enter LMOUNT DATABASE.PAYROLL.ACCTNG You may, as an alternative, use the new VSRESERVESYS command VSRESERVESYS DATABASE.PAYROLL.ACCTNG
