If the issue follows the power supply, the power supply needs to be replaced.
If the issue stays with the node, contact Isilon Technical Support for help troubleshooting the node.
d. If the preceding steps do not resolve the issue, contact Isilon Technical Support.
2. If multiple nodes report power supply issues, confirm the health of power subsystem. The issue is likely environmental.
Check each of the following items:
•
•
•
•
Supplied voltage.
Power quality, such as the correctness of the voltage and the smoothness of the waves.
Uninterruptible Power Supply (UPS) health, such as the ability to provide clean and consistent power.

A temperature sensor on a node indicates an elevated temperature.
Administrator Response
Attempt the following possible solutions. If a solution resolves the issue, there is no need to attempt other possible
solutions:
•
•
Review the chassis inlet temperature statistics, which are included in the event. If the temperature is elevated, the
problem is likely a high ambient temperature in the data center. Address any environmental concerns.
Run the following command:
isi_hw_status
Review the output to determine whether there is a slow or failed fan that was not otherwise reported. To order a
replacement fan, contact Isilon Technical Support.
•
•
Check the temperature of the data center and the airflow within the rack. Address any environmental concerns.
Check for high CPU and disk utilization in the node. High utilization can contribute to high temperatures within the
node.
Cancel or quiet the event.
900030001
Hardware Monitoring failure.
Details
