Tape Volume/Pool: The tape volume label of the currently-mounted tape, if a tape session
is currently in progress.
•
Tape Session #: The number of the ongoing tape session.
•
Uncompressed blocks: The number of uncompressed blocks written to tape.
•
Compressed blocks: The number of compressed blocks written to tape.
•
Uncompressed Bytes: The number of uncompressed bytes written to tape.

Encryption engine rebalancing
If you are currently using encryption and running Fabric OS 6.3.x or earlier, you are hosting tape
and disk target containers on different encryption switches or blades. Beginning with Fabric
OS 6.4, disk and tape target containers can be hosted on the same switch or blade. Hosting both
disk and tape target containers on the same switch or blade might result in a drop in throughput,
but it can reduce cost by reducing the number of switches or blades needed to support encrypted
I/O in environments that use both disk and tape.
The throughput drop can be mitigated by re-balancing the tape and disk target containers across
the encryption engine. This ensures that the tape and disk target containers are distributed within
the encryption engine for maximum throughput.
All nodes within an encryption group must be upgraded to Fabric OS 6.4 or later to support hosting
disk and tape target containers on the same encryption engine. If any node within an encryption
group is running an earlier release, disk and tape containers must continue to be hosted on
separate encryption engines.
