IBM Magstar 3494 manual Reuse of Exported Stacked Volumes

Reuse of Exported Stacked Volumes
	Once all of the logical volumes on an Exported Stacked Volume have been
	imported into a VTS subsystem, the Exported Stacked Volume can be re-used for
	any 3590 application. No cleanup or special processing is required; however, the
	Exported Stacked Volumes remain in the Import category until operator action is
	taken. It is up to the customer 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 re-used as a stacked volume in a VTS or for native use
	on a 3590 subsystem. This would normally be determined by using the tape
	management system to check that there are no logical volumes contained on a
	physical volume previously used 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 re-used.
	Reuse of the physical volumes is accomplished with operator action by using a
	library manager console Manage Import Volumes pop-up window to move the
	Exported Stacked Volumes out of the Import category. (See Figure 130 on
	page 204.) Once they are moved out of the Import category, one of the following
	will happen:
	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 the volumes are to go into. If they are not in a range assigned for
	stacked volumes, the volumes are entered into the library for native 3590 usage
	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 use. If they are not in a range assigned for 3590 native
	use, the volumes are entered into the library for native 3590 usage 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
	will be moved into the library in the Unassigned category, and the Manage
	Unassigned Volumes pop-up window may then be used by the operator to
	change the category to Import or Insert, or to eject the volume.
