NetApp E-Series Storage Disk Test

This test monitors the storage disks in the target NetApp E-Series Storage system and reports the availability of disks. Administrators can instantly get alerted when the disks failed, removed/unresponsive.

Target of the test : NetApp E-Series Storage

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each storage disk in the NetApp E-Series Storage that is currently launched.

Configurable parameters for the test
Parameters	Description
Test Period	How often should the test be executed.
Host	The nick name of the NetApp E-Series Storage component for which this test is to be configured.
Port	Refers to the port at which the specified host listens to. By default, this is Null.
Rest API Port	This is the port at which REST API connectivity is provided. By default, port 4443 is used.
Username and Password	To collect performance metrics from the target storage device, the eG agent should be configured with the credentials of a user who is vested with "read-only" privileges to access REST API of the target storage device. Specify the credentials of such a user in the Username and Password text boxes.
Confirm Password	Confirm the password by retyping it here.
SSL	Set the SSL flag to Yes, if SSL (Secured Socket Layer) is to be used to connect to the target Storage System, and No if it is not.
Timeout Seconds	Specify the time duration for which this test should wait for a response from the storage system in the Timeout text box. By default, this is 120 seconds.
Detailed Diagnosis	To make diagnosis more efficient and accurate, the eG Enterprise embeds an optional detailed diagnostic capability. With this capability, the eG agents can be configured to run detailed, more elaborate tests as and when specific problems are detected. To enable the detailed diagnosis capability of this test for a particular server, choose the On option. To disable the capability, click on the Off option. The option to selectively enable/disable the detailed diagnosis capability will be available only if the following conditions are fulfilled: The eG manager license should allow the detailed diagnosis capability Both the normal and abnormal frequencies configured for the detailed diagnosis measures should not be 0.

Measurements made by the test

Measurement

Description

Measurement Unit

Interpretation

Disk availability

Indicates whether/not this storage disk is available.

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Numeric Value	Measure Value
0	Unavailable
100	Available

Note:

By default, this measure reports the Measure Values discussed above to indicate the availability of the storage disk. In the graph of this measure however, availability is represented using the numeric equivalents only.

Disk status

Indicates the current status of this storage disk.

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Numeric Value	Measure Value
100	Optimal
95	Replaced
90	Bypassed
85	Unresponsive
80	Removed
75	Incompatible
70	Data Relocation
65	PreFailCopy
60	PreFailCopy Pending
55	Sanitizing
50	Undefined
45	Failed

Note:

By default, this measure reports the Measure Values discussed above to indicate the status of the storage disk. In the graph of this measure however, status is represented using the numeric equivalents only.

The detailed diagnosis of this measure reveals the description of why the disk in such status.

Available to create volume

Indicates whether/not this storage disk is available to create a new volume.

The values that this measure can report and their corresponding numeric values are discussed in the table below:

Numeric Value	Measure Value
0	No
100	Yes

Note:

By default, this measure reports the Measure Values discussed above to indicate the availability of the storage disk to create a new volume. In the graph of this measure however, availability is represented using the numeric equivalents only.
