Reopens a volume set that has been closed with VSCLOSE. The volume set becomes available for use again. (Native Mode)

Syntax

>VSOPEN volumesetname [[;PARTVS=] { USER BACKUP }]

Parameters

volume- setname

The volume set to be opened. You must specify an unambiguous name. MPE/iX does not accept part of a volumesetname and defaults the remainder of the name. Refer to "Operation Notes."

PARTVS

This option is available only with the Mirrored Disk/iX, a separately purchased product. For information, refer to Mirrored Disk/iX User's Guide (30349-90003). This parameter only applies to a previously split volume set. It notifies the system which split volume set half is to be opened.

USER

Open only the user volumes.

BACKUP

Open only the backup volumes.

If PARTVS is not specified, both volume set halves are opened. If PARTVS is specified for a non split volume set, an error is returned and the volume set is not opened.

Operation Notes

This command notifies the system to open the specified volume set. Because bringing a volume set online opens the set by default, this command is needed only for a volume set for which a VSCLOSE command has been issued.

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, such as:

 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. This command may be issued only from the system console unless distributed to other users with the ALLOW command.

Examples

To open the volume set ACCOUNTING_PAYROLL, enter:

 VSOPEN ACCOUNTING_PAYROLL
