Clariion Storage Processors Test

The storage processor enables the administrator in serving the purpose of the following:

  • Creating raid group
  • Binding luns
  • All CLI commands can be executed
  • Read/write operations from external server to SAN

This test monitors the current state and I/O activity on each of the storage processors supported by the storage system.

Target of the test : An EMC CLARiiON storage device

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each storage processor on the storage system.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.


The IP address of the storage device for which this test is to be configured.


The port number at which the storage device listens. The default is NULL.


By default, the host IP will be displayed here. If the eG agent has also been configured to use the SMI-S provider for metrics collection, then the IP address of host on which the SMI-S provider has been installed, will be displayed here by default. In this case, you should change the value of this parameter to reflect the IP address of the EMC CLARiiON storage device. However, if the eG agent uses only the NaviSphere CLI for monitoring, then the default settings can remain. 


The eG agent uses the command-line utility, NaviSecCli.exe, which is part of the NaviSphere Management Suite, to communicate with and monitor the storage device. To enable the eG agent to invoke the CLI, configure the full path to the CLI in the NaviseccliPath text box.

User Name and Password

Provide the credentials of a user who is authorized to access the storage device in the User Name and Password text boxes.

Confirm Password

Confirm the password by retyping it here.


Indicate the duration (in seconds) for which this test should wait for a response from the storage device. By default, this is set to 120 seconds. Note that the 'Timeout' value should always be set between 3 and 600 seconds only.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Fault state

Indicates the current state of this storage processor.


If the storage processor is up and running, then the value of this measure will be On. If not, then this measure will report the value Off.

The numeric values that correspond to the aforesaid states are as follows:

State Numeric Value
On 1
Off 0


By default, this measure reports the values On or Off to indicate the status of a storage processor. The graph of this measure however, represents the processor status using the numeric equivalents - 0 or 1.


Indicates percent utilization of the storage processor.


The numeric value that corresponds to individual states are listed below:

  • 90%-Critical
  • 80%-Major
  • 60%-Minor


Indicates the percentage of time for which this storage processor was idle.


This value varies with respect to the value of the Busy measure.

Read requests

Indicates the rate of read requests to this storage processor.


Comparing the value of these measures across storage processors will clearly indicate which processor is overloaded – it could also shed light on irregularities in load balancing across the processors. 

Write requests

Indicates the rate of write requests to this storage processor.


Total throughput

Indicates the sum of read and write request rates.



Data writes

Indicates the rate at which data is written via this storage processor.



Data reads

Indicates the rate at which data is read via this storage processor.
