If the mount fails, see Maintaining mounts and locks on page 48 for more information.
6. After the backup begins, you can monitor the progress from the Virtual Media - Operation
page. In the kb/sec and size(MB) columns, you can see the megabytes that have been
backed up and the backup rate:
After the backup completes, you can verify that the size of the virtual tape has changed.
You can also monitor progress from the System Status page, which shows the current
transfer rate (if enabled).
When the backup is finished, VTS unloads the virtual tape. If the pool was configured to
autoload virtual tapes, it mounts the next virtual tape in the pool.
Erasing and deleting virtual tapes
You can erase the contents of a virtual tape or delete the tape. Erasing removes the data
stored on the virtual tape but leaves the metadata and tape label. Deleting a virtual tape
removes it altogether, and its data cannot be recovered through migration. When you erase a
virtual tape, its modification date is not updated; the ctime (inode change time) is updated.
You can also automate these operations from the NonStop server using the VTSPolicy
command if Event Management Service communication is configured. (See
Configuring EMS
Communication on page 23.) To automate erasure from the VTS server, see Using Scan/
Cleanup on page 67.
You can erase or delete a single virtual tape from the Virtual Media - Operation page and the
Virtual Media - Cartridge Maintenance page. You can erase or delete multiple virtual tapes
from the Virtual Media - Cartridge Maintenance page only.
