VSCLOSE
VSCLOSE
Informs the system to close the specified volume set and take it offline. (Native Mode)
Syntax
VSCLOSE volumesetname[ [ ;PARTVS=] { USER BACKUP } ] [ ;NOW ;SPLIT ]
Parameters
volume- setname The volume set that is to be closed. Any user who is accessing a file at the
time this command is issued is allowed to finish accessing the file.
However, users who are not accessing files are unable to open files on the
volume set, and VSRESERVE and MOUNT requests are denied. Refer to
"Operation Notes," below.
PARTVS This option is available only with the Mirrored Disk/XL, a separately
purchased product. For information, refer to !Mirrored Disk User's Guide>
Mirrored Disk/iX User's Guide (30349-90003). This parameter only
applies to a previously split volume set. Specify it when you want only half
of split volume set to be closed.
USER Close only the user volumes.
BACKUP Close only the backup volumes.
If PARTVS is not specified, both volume set halves are closed. If PARTVS is
specified for a nonsplit volume set, an error is returned and the volume set
is not closed.
NOW Instructs the system to abort any job or session that is using any file that
resides in the specified volume set. However, if a VSRESERVESYS or an
LMOUNT command has already been issued for the specified volume set,
then the operator should execute a VSRELEASESYS command, followed by
a VSCLOSE ;NOW command, in order to take the volume set offline.
The NOW parameter permits the operator to remove a volume set without
having to use VSUSER and then perform an ABORTJOB on the users of the
volume set. This command may be issued only from the system console.
SPLIT 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). It splits the volume set into user volumes and
backup volumes if it is a mirrored volume set and if it is in the proper
state.
The SPLIT option cannot be used with the NOW option. All members of the
volume set and both members of each pair must be present. There can be
no repair taking place. Both members of each volume pair must be
identical at the time of the split. There can be no users logged onto the
volume set when the split is processed.
