VNXe Fiber Channel Port Test

By periodically checking the health of the ports and measuring the I/O load on the ports, you can identify overloaded ports, isolate the storage processor they support, and thus proactively detect potential/existing load-balancing irregularities and/or processing bottlenecks with the storage processors. The VNXe Fiber Channel Port test facilitates this port check. For every port configured on each of the storage processors (A and B) supported by the target storage system, this test reports the health of the ports, the I/O load on the ports and the processing ability of the ports. In the process, the test not only points administrators to overloaded ports, but also puts a finger on ports that are slow when processing I/O requests.

Target of the test : An EMC VNXe Storage system

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each Fiber Channel Port on the target storage system being monitored

Configurable parameters for the test
Parameters Description

Test Period

How often should the test be executed.

Host

The host for which the test is to be configured.

Unisphere CLI Path

The eG agent uses the command-line utility, UEMCli.exe, which is part of the UniSphere 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 UniSphere CLI Path text box.

Username and Password

Provide the credentials of a user possessing monitor role to access the storage device in the Username and Password text boxes.

Confirm Password

Confirm the password by retyping it here.

VNXe Version

Select the version of the target EMC VNXe storage system that is to be monitored from this list. By default, 1600 will be chosen from this list.

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 abnormal frequencies configured for the detailed diagnosis measures should not be 0.
