Chassis Fan Modules Test

The Cisco UCS Blade server chassis contains eight hot-swappable fan modules. These fan modules ensure that the internals of the chassis always receive adequate air flow and the temperature within the chassis is maintained at acceptable levels at all times. Snags in the functioning of the fan module can hence hamper air flow, which in turn may have disastrous effects on the health of the other chassis components.

By periodically monitoring the availability, overall health, operational state, and the temperature of fan module, you can promptly detect abnormalities in the operations of the module and initiate speedy remedial measures. This test does just that.

Target of the test : A Cisco UCS manager

Agent deploying the test : A remote agent

Outputs of the test : One set of results for each fan module available in each chassis managed by the Cisco UCS manager being monitored.

Configurable parameters for the test
Parameter Description

Test Period

How often should the test be executed.

Host

The IP address of the host for which the test is being configured.

Port

The variable name of the port at which the specified host listens.

UCS User and
UCS Password

Provide the credentials of a user with at least read-only privileges to the target Cisco UCS manager.

Confirm Password

Confirm the password by retyping it here.

SSL

By default, the Cisco UCS manager is SSL-enabled. Accordingly, the SSL flag is set to Yes by default.

Web Port

By default, in most virtualized environments, Cisco UCS manager listens on port 80 (if not SSL-enabeld) or on port 443 (if SSL-enabled) only. This implies that while monitoring Cisco UCS manager, the eG agent, by default, connects to port 80 or 443, depending upon the SSL-enabled status of Cisco UCS manager - i.e., if Cisco UCS manager is not SSL-enabled (i.e., if the SSL flag above is set to No), then the eG agent connects to Cisco UCS manager using port 80 by default, and if Cisco UCS manager is SSL-enabled (i.e., if the SSL flag is set to Yes), then the agent-Cisco UCS manager communication occurs via port 443 by default. Accordingly, the WebPort parameter is set to default by default.

In some environments however, the default ports 80 or 443 might not apply. In such a case, against the WebPort parameter, you can specify the exact port at which the Cisco UCS manager in your environment listens, so that the eG agent communicates with that port for collecting metrics from the Cisco UCS manager.

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.
