Measures reported by NetCluDiskSateTest

This test reports the current state of each disk in the NetApp Cluster. Using this test, you can easily figure out the the disks that currently offline, the disks that are currently in the Replacing/Reconstructing/Failed states.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Is_failed Indicates whether/not the status of this disk is Failed.   This measure reports a value Yes if the status of the disk is Failed and No if otherwise.

The values that this measure can report and their corresponding numeric values have been listed in the table below.
Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether the status of this disk is Failed or not. However, in the graph of this measure, Measure Values will be represented using the corresponding numeric equivalents i.e., 0 or 1.

Is_offline Indicates whether/not the status of this disk is Offline.   This measure reports a value Yes if the disk is Offline and No if otherwise.

The values that this measure can report and their corresponding numeric values have been listed in the table below.
Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether the status of this disk is Offline or not. However, in the graph of this measure, Measure Values will be represented using the corresponding numeric equivalents i.e., 0 or 1.

Is_prefailed Indicates whether/not the status of this disk is Prefailed.   The disks that are manually failed due to excessive error logging are termed as Prefailed disks. The contents of these disks are copied into suitable replacement disks i.e., the spare disks available in the storage system.

This measure reports a value Yes if the status of the disk is Prefailed and No if otherwise.

The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether the status of the disk is Prefailed or not. However, in the graph of this measure, Measure Values will be represented using the corresponding numeric equivalents i.e., 0 or 1.

Is_reconstructing Indicates whether/not the status of this disk is Reconstructing.   This measure reports a value Yes if the status of the disk is Reconstructing and No if otherwise.

The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether the status of this disk is Reconstructing or not. However, in the graph of this measure, Measure Values will be represented using the corresponding numeric equivalents i.e., 0 or 1..

Is_replacing Indicates whether/not the status of the disk is Replacing.   Mismatched disks that are part of an aggregate can be replaced with a more suitable spare disk without disrupting the data service. This process uses the Rapid RAID Recovery process to copy the data from the disk being replaced to a specified spare disk. Frequently replacing the disks will lead to the system degradation. Therefore, the frequent replacement of the disks needs to be avoided by proper initial configuration.

This measure reports a value Yes if the status of the disk is Replacing and No if otherwise.

The values that this measure can report and their corresponding numeric values have been listed in the table below.

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the above-mentioned Measure Values while indicating whether this disk is a replacing disk or not. However, in the graph of this measure, Measure Values will be represented using the corresponding numeric equivalents i.e., 0 or 1.
