Erasing
Erasing a tape physically deletes all backups stored on the tape and removes the information about
these backups from the database. However the information about the tape itself remains in the
database.
After erasing, a tape located in the Unrecognized tapes or Imported tapes pool is moved to the Free
tapes pool. A tape located in any other pool is not moved.
You can apply the operation to one tape at a time.
To erase a tape:
1. In the Navigation tree, click Tape management. If connected to the management server, select
the storage node to which your tape device is attached.
2. Click the pool that contains the necessary tape, and then select the required tape.
3. Click Erase. The system prompts to confirm the operation.
4. Click OK to start the operation.
Details. You cannot cancel the erasing operation.
Rescanning
The information about the contents of tapes is stored in a dedicated database. The rescanning
operation reads the contents of tapes and updates the database if the information in it mismatches
the data stored on tapes. The archives detected as a result of the operation are placed in the
specified vault.
Within one operation, you can rescan tapes of one pool. Only online tapes can be selected for the
operation.
Run the rescanning:

If the database of a storage node or managed machine is lost or damaged.

If information about a tape in the database is out of date (for example, a tape contents were
modified by another storage node or agent).

To obtain access to backups stored on tapes when working under bootable media.

If you have mistakenly removed (p. 210) the information about a tape from the database. When
you rescan a removed tape, the backups stored on it reappear in the database and become
available for data recovery.

If backups were deleted from a tape either manually or through retention rules (p. 441) but you
want them to become accessible for data recovery. Before rescanning such a tape, eject (p. 206)
it, remove (p. 210) the information about it from the database, and then insert the tape into the
tape device again.
To rescan tapes:
1. If you have no tape-based vault (p. 210) associated with the device you loaded the tapes to,
create one.
2. In the Navigation tree, click Tape management. If connected to the management server, select
the storage node to which your tape device is attached.
3. Perform the fast inventorying (p. 208).
Note During the inventorying, do not select the Move newly detected tapes from the 'Unrecognized
tapes' or 'Imported tapes' pools to the 'Free tapes' pool check box.
