6.3.2.2
Sharing tape medium among multiple libraries (advanced)
Multiple Libraries can share tape medium by using either of the following two methods:
1.
Sharing on a library basis (Register the same master key.)
2.
Sharing on a tape basis (Register an encryption key for each tape medium.)
This chapter describes how to register an encryption key for each tape medium.
To register an encryption key for each tape medium, select “Import” for “Key Type” in [Encryption
Detail]. You can input the encryption key manually or by using a file. For details about how to
register the encryption key, see Section 6.3.3.2.
Be sure to back up the KEY database after registering the encryption key for each
tape. If the database is not backed up and encryption key information is
corrupted due to a device failure, it might become impossible to decrypt data
recorded in tape medium.
6.3.3
Importing and Exporting the Encryption Key(For Each Tape Medium)
You can set an encryption key to each tape medium. When you set an individual encryption key to
each tape medium, the set encryption keys are saved in the KEY database in the Library, so you can
use them without setting them again after turning the Library on and off.
Be sure to back up the KEY database after importing an encryption key. If the
KEY database is not backed up and is then corrupted due to a device failure, it
might become impossible to decrypt the encrypted media.
This encryption key management function can manage one encryption key for
each tape media.
Be sure to set the same encryption key when setting the encryption key to tape
media for which an encryption key is already set. Note that tape media in which
data has been recorded using multiple encryption keys cannot be used for this
encryption key management function.
