Tape LUN statistics
This feature enables you to view and clear statistics for tape LUNs. These statistics include the
number of compressed blocks, uncompressed blocks, compressed bytes and uncompressed bytes
written to a tape LUN.
The tape LUN statistics are cumulative and change as the host writes more data on tape. You can
clear the statistics to monitor compression ratio of ongoing host I/Os.
The encryption management application allows you to select tape LUN from either a tape LUN
container through the Encryption Targets dialog box, or from the Target Tape LUNs dialog box.
