Just to summarize the answer from the technote page.. 'Data is encrypted during WRITE operations, when the encryption key is passed from the server to the drive. Data is decrypted on READ operations.' I will not need to relabel the volumes since the label is not encrypted, just data written in the write process.
Consider the method used for encryption, as the document also says: "When using encryption-capable drives with the Application method, a new format will be used to write encrypted data to tapes. If data is written to volumes using the new format and if the volumes are then returned to scratch, they will contain labels that are only readable by encryption-enabled drives. To use these scratch volumes in a drive that is not enabled for encryption, either because the hardware is not capable of encryption or because the encryption method is set to OFF, you must relabel them."
