Changing Watermark Parameters

Watermarks help you determine disk space thresholds for your file 

system. These thresholds determine the point at which StorNext applies 

or stops applying a truncation policy. This function also allows you to 

specify a minimum usage percentage, which is the percentage of 

occupied disk space the nightly truncation policy attempts to achieve.
