Show volume efficiency statistics
The volume efficiency stat command displays efficiency statistics. The output depends on the parameters specified with the command. If no parameters are specified, the command displays the following efficiency statistics fields for all the volumes:
To display detailed information, run the command with -instance parameter.
The following example displays default efficiency statistics for all the volumes.
cluster1::> volume efficiency stat Vserver: vs1 Volume: vol2 Inline Compression Attempts: 0 Inline Incompressible CGs: 0 Vserver: vs1 Volume: vol3 Inline Compression Attempts: 0 Inline Incompressible CGs: 0
At the diagnostic level, the output displays the information below.
