VNXe Fan Test

Each Storage Processor has three fan modules above it to dissipate heat away from the storage system. For the system to stay operational, atleast two of the three fans on each SP must be active. If either Storage Processor has two or more fans inactive, the system will save cache contents and shut down automatically. In large production environments, administrators may not desire frequent shut downs of their mission critical systems. Therefore, it is necessary for the administrators to frequently monitor the hardware components of the storage system and ensure that a hardware failure does not contribute to the shut down of the storage system. The VNXe Fans test helps administrators in this regard!

This test reports the current health of each cooling fan in the target storage system. By closely monitoring the health of the cooling fans, fans that are running abnormally and fans that have failed can be identified and replaced at a faster pace!

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 fan 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 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
Health state	Indicates the current health of this cooling fan.		The values reported by this measure and its numeric equivalents are mentioned in the table below: Measure value Numeric Value Normal 0 Attention 1 Unknown 2 Degraded/Warning 3 Minor failure 4 Major failure 5 Critical failure 6 Non-recoverable error 7 Note: By default, this measure reports the Measure Values listed in the table above to indicate the current health of this cooling fan. The graph of this measure however is represented using the numeric equivalents only - 0 to 7. The detailed diagnosis of this measure lists the ID of the fan, the slot, health, serial number and model of the fan.
