Click Configure from the Volume Settings to modify the various aspects of the PSM volume
attributes. Some of the fields will appear read-only if there are active snapshots. The Restore
Defaults button will re-establish the system defaults. If it is desired to remove the cache files
all together the CLEANVOL.EXE can be used to remove them; see the section on clearing the
cache file. Also note the section on granular size in this chapter, prior to updating the percent
reserved for cache size. The default value is 10 percent.
