The VSOPEN command tells the system to open the specified volume set. The volume set becomes available for use again. Since 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 PARTVS parameter has been added to support split-volume backup.
A default VSOPEN of a split-volume set attempts to open both volume set halves. If it finds that only one of the halves is present, it opens it and returns no warning for the absent volume set half.
This command may be issued from a session, a job, or in break, but not from a program. Pressing CTRLY has no effect on this command. This command may be issued only from the system console.
Task |
 |
Opens a volume set and brings it online.
Syntax |
|
VSOPEN volumesetname [ [;PARTVS=] {USER
BACKUP}]
|
- volumesetname
The volume set that is to be opened. The name must be unambiguous; that is, MPE does not accept part of a volumesetname and default the remainder of the name. Required.
- PARTVS
This parameter is only applicable to a previously split-volume set. It tells 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 nonsplit-volume set, an error is returned and the volume set is not opened.

This example shows how to use the VSOPEN command with the PARTVS parameter:
:VSOPEN PROD_SET; PARTVS=USER
