Measures reported by DellHwDriveTest

This test reports the current state of the logical and physical drives of a disk array, and also promptly alerts administrations to current or potential contention for disk space on a disk array.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
diskState Indicates the current status of this disk array.   The values this can measure report and their numeric equivalents are available in the table below:

Measure Value Numeric Value
Unknown 0
Ready 1

Foreign 39
Clear 40
Unsupported 41
PermanentlyDegraded 52
Incompatible 53

Note:

This measure reports the Measure Values listed in the table above to indicate the status of the disk array. However, in the graph of this measure, array status is indicated using only the Numeric Values listed in the above table.
diskSize Indicates the total size of this disk array. MB  
usedSpace Indicates the amount of space in this disk array that is being used currently. MB Ideally, the value of this measure should be low.
freeSpace Indicates the amount of space in this disk array that is currently unused. MB Ideally, the value of this measure should be high.
State Indicates whether/not this disk array is currently experiencing any critical/non-recoverable failures.   The values this can measure report and their numeric equivalents are available in the table below:

Measure Value Numeric Value
Other 1
Unknown 2
OK 3
Non-critical 4
Critical 5
Non-recoverable 6

Note:

This measure reports the Measure Values listed in the table above to indicate the severity state of the disk array. However, in the graph of this measure, array status is indicated using only the Numeric Values listed in the above table.
arrayNegotiatedSpeed Indicates the speed at which this disk array is currently running. MPS Compare the value of this measure across disk array to know which array is currently operating at an abnormal speed.
freeSpacePct Indicates the percentage of free space in this disk array. Percent A very low value or a consistent decrease in this value is a cause for concern, as it indicates a steady erosion of disk space in the array.
