Monitoring Physical Disks

Physical disks must be monitored to avoid loss of data, unavailability and performance degradation. When available, the S.M.A.R.T. technology will be used to predict a disk failure before it occurs.

Depending on the available information, the PredictedFailure, ErrorCount and/or Status parameters will be displayed for each discovered physical disk:

•	The PredictedFailure parameter uses the S.M.A.R.T. technology to predict physical disk failures. An alert will be triggered if it is predicted that the Physical Disk will soon break down.

•	The ErrorCount parameter is incremented each time an error occurs on this physical disk. An alert is raised from the first detected error. The operator can reset the counter and clear the alert through the Acknowledge ErrorCount Alert and Reset KM command in the PATROL Console.

•	The Status parameter represents the current status of the physical disk. An alert is triggered if the physical disk is not available for proper operation.
