Measures reported by VNXeFanTest

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 VNXeFanTest 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!

Outputs of the test : One set of results for each fan on the target storage system being monitored.

The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
healthStatus 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.
