VSOPEN
VSOPEN
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:
