Hardware Physical Disk

PATROL Class: MS_HW_PHYSICALDISK - Monitor Type: MONITOR - Monitor Category: System
No CDM Class defined.

Monitors a specific physical disk for 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.

Attributes (Parameters)

Name PATROL Name Units Default Thresholds Description
Device Not Ready Error Count DeviceNotReadyErrorCount errors

 ALARM
if ≥ 1 errors

Number of not ready device errors that the disk has encountered since the last reinitialization, or since the last manual reset.

Value set by physicalDiskColl.

Type: Statistics

Error Count ErrorCount errors None

Number of errors encountered by the physical disk since the last reinitialization or since the last manual reset. This parameter is incremented each time an error occurs on this physical disk. An alert is raised automatically from the first detected error. The operator can reset the counter and clear the alert through the menu Acknowledge Error Count Alerts and Reset. Resetting the ErrorCount parameter can also be configured to be performed automatically.

Value set by physicalDiskColl.

Type: Statistics

Hard Error Count HardErrorCount errors

 ALARM
if ≥ 1 errors

Number of hard errors that the disk has encountered since the last reinitialization, or since the last manual reset.

Value set by physicalDiskColl.

Type: Statistics

Illegal Request Error Count IllegalRequestErrorCount errors

 ALARM
if ≥ 1 errors

Number of illegal request errors that the disk has encountered since the last reinitialization, or since the last manual reset.

Value set by physicalDiskColl.

Type: Statistics

Media Error Count MediaErrorCount errors

 ALARM
if ≥ 1 errors

Number of media errors that the disk has encountered since the last reinitialization, or since the last manual reset.

Value set by physicalDiskColl.

Type: Statistics

No Device Error Count NoDeviceErrorCount errors

 ALARM
if ≥ 1 errors

Number of no device errors that the disk has encountered since the last reinitialization, or since the last manual reset.

Value set by physicalDiskColl.

Type: Statistics

Predicted Failure PredictedFailure 0 = OK
1 = Failure Predicted

 WARN
if = 1 (Failure Predicted)

Informs if a failure is predicted.

Value set by physicalDiskColl.

Type: Availability

Present Present 0 = Missing
1 = Present

 ALARM
if = 0 (Missing)

Availability of the physical disk.

Value set by physicalDiskColl.

Type: Availability

Recoverable Error Count RecoverableErrorCount errors None

Number of recoverable errors that the disk has encountered since the last reinitialization, or since the last manual reset.

Value set by physicalDiskColl.

Type: Statistics

Status Status 0 = OK
1 = Degraded
2 = Failed

 WARN
if = 1 (Degraded)

 ALARM
if = 2 (Failed)

Physical disk status.

Value set by physicalDiskColl.

Type: Availability - Default graph

Status Information StatusInformation None None

Additional (textual) information about the current status of the physical disk.

Value set by physicalDiskColl.

Type: Text

Transport Error Count TransportErrorCount errors

 ALARM
if ≥ 1 errors

Number of transport errors that the disk has encountered since the last reinitialization, or since the last manual reset.

Value set by physicalDiskColl.
