Reuse of Exported Stacked Volumes
When all of the logical volumes on an Exported Stacked Volume have been
imported into a VTS, the Exported Stacked Volume can be reused for any 3590 or
3592 application. No cleanup or special processing is required; however, the
Exported Stacked Volumes remain in the Import category until you take action. It
is up to you to determine when all of the logical volumes on an Exported Stacked
Volume have been imported or are no longer needed and that the physical volume
can be reused as a stacked volume in a VTS or for native use on a 3590 or 3592
subsystem. This would be determined normally by using the tape management
system to check that there are no logical volumes contained on a physical volume
used previously as an Exported Stacked Volume. For example, the
RMM SEARCHVOLUME command can be used to make this determination as
follows:
RMM SV CONTAINER(xxxxxx)
where xxxxxx is the volser of the Exported Stacked Volume in question.
If no volumes are returned, all of the logical volumes on the Exported Stacked
Volume have been imported, and the volume may be reused.
Reuse of the physical volumes is accomplished with operator action by using a
Library Manager console Manage Import Volumes window to move the Exported
Stacked Volumes out of the Import category (see the figure of the Manage Import
Volumes window in
″
System Management
″
). When they are moved out of the
Import category, one of the following happens:
v The volumes are moved into the Insert category if they are to be used as scratch
stacked volumes in a VTS within the current physical library. The volser of the
physical volumes must fall in the range assigned for stacked volumes in the
library partition into which the volumes are to go. If they are not in a range
assigned for stacked volumes, the volumes are entered into the 3494 for native
3590 or 3592 use as the default.
v
The volumes are moved into the Insert category if they are to be used as native
3590 cartridges. The volsers of the physical volumes must fall in the range
assigned for native 3590 or 3592 use. If they are not in a range assigned for 3590
native use, the volumes are entered into the 3494 for native 3590 or 3592 use as
the default.
v
Otherwise, the volumes are ejected for other use or later disposition. Exported
Stacked Volumes may be placed in the convenience I/O station at any time.
They are moved into the 3494 in the Unassigned category. You may then use the
Manage Unassigned Volumes window to change the category to Import or Insert
or to eject the volume.
