Clariion Storage Ports Test

This test reports the current status and overall health of each port on each storage processor supported by the storage system being monitored.

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 the each storage processor port on the storage system.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

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

Port

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

CLARiiON IP

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. 

NaviseccliPath

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.

Ignore Disabled SPPorts

By default, this flag is set to No, indicating that the test monitors all ports on all storage processors by default. Set this flag to Yes if you want the test to consider only the 'enabled' storage processor pors for monitoring.

Exclude SPPorts

Provide a comma-separated list of PortName PortID pairs that you want to exclude from the monitoring scope of this test. For instance, your specification can be: SPA 0,SPA 1,SPB 2. By default, this is set to none indicating that no ports are excluded by default.

Timeout

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.

DD Frequency

Refers to the frequency with which detailed diagnosis measures are to be generated for this test. The default is 1:1. This indicates that, by default, detailed measures will be generated every time this test runs, and also every time the test detects a problem. You can modify this frequency, if you so desire. Also, if you intend to disable the detailed diagnosis capability for this test, you can do so by specifying none against DD frequency. 

Detailed Diagnosis

To make diagnosis more efficient and accurate, the eG Enterprise suite 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 abnormalfrequencies configured for the detailed diagnosis measures should not be 0.
Measurements made by the test
Measurement Description Measurement Unit Interpretation

Link state

Indicates the link state of this storage processor port.

 

If the storage port is up and running, then this measure will report the value Up. If not, then, this measure will report the value Down.

The numeric values that correspond to each of the states discussed above are available in the table below:

State Numeric Value
Up 1
Down 0

Note:

By default, this measure reports the values Up or Down to indicate the status of a port. The graph of this measure however, represents the port status using the numeric equivalents - 0 or 1.

Port state

Indicates the current state of this port.

Status

The operational state of a port can be Online, Offline or Not Applicable.

The numeric values that correspond to each of the states discussed above are available in the table below:

State Numeric Value
Online 1
Offline 2
Not Applicable 0

Note:

By default, this measure reports the values Up or Down to indicate the status of a port. The graph of this measure however, represents the port status using the numeric equivalents - 0 or 1.

SFP state

Indicates the SFP state of this port.

Number

This measure can report any one of the following values:

  • Online
  • Faulted
  • Removed

The numeric values that correspond to each of the states discussed above are available in the table below:

State Numeric Value
Online 1
Faulted 2
Removed 0

Note:

By default, this measure reports the values Up or Down to indicate the status of a port. The graph of this measure however, represents the port status using the numeric equivalents - 0 or 1.

Reads

Indicates the number of reads per second made on this port.

Number

Comparing the value of these measures across ports will clearly indicate which port is overloaded - it could also shed light on irregularities in load balancing across the ports. 

Writes

Indicates the number of writes per second made on this port.

Number

Data reads

Indicates the rate at which data is read through this port.

Blocks/Sec

 

Data writes

Indicates the rate at which data is written through this port.
