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


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


volumesetname 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 parameter is only applicable 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.


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
XL, and so is MY.OWN.PERSONAL.VOLUME.SET; similarly, A.B.C is

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
XL volume set commands. For example, the command below works:

Vcommand A.B.C

The next command, however, will fail to access the volume set,
since you cannot specify the first part of the volume set name
alone and expect the group and account to default.

Vcommand A

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.
