Notifies the system to keep a particular volume set online. The equivalent compatibility mode command is MOUNT. (Native Mode)

Syntax

>VSRESERVE [volumesetname] [;GEN=genindex]

Parameters

volume- setname

The name of the MPE/iX volume set to be kept online. If you omit the parameter, the request is issued for the home volume set of the user's logon group and account. Refer to "Operation Notes."

genindex

A value from -1 to 32,767 specifying which generation of the volume set is to be kept online. If you omit the parameter, the system does not check the generation version of the specified volume set.

Operation Notes

This command calls for the specified volume set to be kept online, and prevents the console operator from taking a particular volume set offline. Once this is done, the volume set is designated as being in use by the user. It remains in this reserved state until the user issues a VSRELEASE command or the operator issues a VSCLOSE ;NOW command; or until the user logs off.

The MPE/iX naming convention for volume sets differs from that of MPE V/E for private volumes.

In MPE V/E, the name A.B.C indicates that B is the name of a group and that C is the name of an account. MPE/iX accepts that name, but no interpretation is made as to the referencing of B and C. Instead, MPE/iX treats A.B.C as a single, long string name. It is the flexibility of the MPE/iX naming convention that makes it possible for MPE/iX to work with a volume set designated A.B.C.

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.

A volume set called MY_OWN_PERSONAL_VOLUME_SET is acceptable in MPE/iX, and so is MY.OWN.PERSONAL.VOLUME.SET; similarly, A.B.C is acceptable.

If a volume set is named according to the MPE V/E naming convention (A.B.C), you must use an unambiguous reference when using the MPE/iX volume set commands:

 Vcommand A.B.C

Entering Vcommand A fails to access the volume set. You cannot specify the first part of the volume set name alone and expect the group and account to default.

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.

Example

To request that volume set ACCOUNTING_PAYROLL be kept online, enter:

 VSRESERVE ACCOUNTING_PAYROLL
