Abstract: Storage array health scores based on alerts are auto-corrected by using alert validation and alert matching to identify missed, stale, and redundant alerts. In response to restoration of an event daemon or reboot of a storage management server, each alert associated with each storage array is validated to determine whether current state of storage array hardware or a logical object differs from the state indicated in the alert. Alerts that differ from current state are updated or invalidated and the health score is recalculated. Responsive to receipt of a new alert, existing alerts associated with the same storage array hardware or logical object are identified and Jaro-Winkler distance between the identified alerts and the new alert is calculated. Any existing alert for which the Jaro-Winkler distance relative to the new alert is greater than or equal to 0.9 is deleted and the health score is recalculated.

The sensing assembly 20 comprises an accelerometer 21, gyroscope 22, and gripping force sensor 23 and may be packaged within a protective housing (not shown).
