Virtual volumes that have been exported or externalized to a physical volume are now processed by the vaulting system. Once the VTX bit x'20' FLAG5 has been turned on in the TMC record, virtual tapes continue to be moved according to the VPD rule, but slot assignment is bypassed.
The slot number is set to a dummy value of 9,999,999 (a "virtual slot"). This virtual-slot number of 9,999,999 will be displayed on any ISPF display, or the TI display as well as the Vantage/GUI display.
These exported virtual volumes do not appear on picking or distribution list (since there is no physical cartridge to move). They are displayed on the inventory list along with the physical container volume (ACTVOL) in place of the slot number preceded by an asterisk (*). So, on the inventory list the slot number might be displayed as *C12345 when C12345 is the container volume that the virtual volume has been exported onto.
