6.2.3 Checking tape media Information

You can display information about the encryption of a specified slot by displaying Slot Information
from [Library Map].See section 5.6.3.2.

6.2.3.1 Sharing tape medium among multiple libraries

If you set the same master key to different Libraries, they can share tape medium.
Using one master key, you can share tape medium for which encryption keys were
automatically generated from the master key. Note that tape medium using
encryption keys generated by using different master keys or other methods
cannot be shared.
For details about how to share tape medium using these encryption keys, see
"6.3
Advance Operation of encryption key management function
1. To register the same master key with multiple libraries
When setting the same master key to multiple Libraries, you can easily register the master key
by exporting the master key registered with the first Library and importing it to the second and
subsequent Libraries.

6.2.4.1 Backup of Encryption Key (Basic Operation)

It is necessary to back up encryption information in advance so that you can use it even if the
encryption information within the Library is corrupted due to a device failure or other cause.
Operation Method and Backup of Encryption Information
Basic operation
Advanced operation
You can save the master key into a file by using the master key export function.
For details about how to export the master key, see "6.2.1.5 Exporting (backing up) the master
key "
Because it is not necessary to change the registered master key you set, one
backup should be enough.
However, note that you should back up the master key again after changing it.
For details about how to change the master key and notes for when changing it,
see "6.3.4
See "6.2.1.4 Registering (importing) the master key ".
See "6.2.1.5 Exporting (backing up) the master key ".
