This window is used to define Warning and Critical thresholds unique to a pa rticular storage subsystem,
overriding the values defined in the disk storage class. The user may modify either the Warning percent,
Critical percent or both for one or more of the listed subsystems. Select a subsystem from the list and
then modify the values on the lower portion of the window. When the new values have been entered,
select Update to commit the changes. To remove the overridden threshold values, select the Set To
Defaults button. The changes will be committed and displayed in the Subsystem Thresholds table.
After any modifications to the subsystem-specific thresholds, the Core Server and Migration Purge
Server for those subsystems must be recycled to make the changes effective.
