You can modify the efficiency operation schedule to run deduplication or data compression when the number of new blocks written to the volume after the previous efficiency operation (performed manually or scheduled) exceeds a specified threshold percentage.
About this task
If the
schedule option is set to
auto, the scheduled efficiency operation runs when the amount of new data exceeds the specified percentage. The default threshold value is 20 percent. This threshold value is the percentage of the total number of blocks already processed by the efficiency operation.
Step
- Modify the threshold percentage value by entering the following command:sis config -s auto@num path
num is a two-digit number to specify the percentage.
path is the complete path to the volume.
Example
The following command modifies the threshold percentage value to 30 percent for the volume VolA:sis config -s auto@30 /vol/VolA
