CPU throttling.
Details
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.
900090046
Redundant power supply failure on expansion chassis.
Details
The issue is caused by one of the following conditions:
•
•
One of the power supplies in the node is not providing power.
The power (AC) provided from the electrical outlet to one or both power supplies is insufficient.
The LED light indicates the power supply status. (The LED light is on the inside of the node, but is visible on the back
panel.)
•

•
•
•
Steady green (applies to all node models): Status is good.
Blinking green (applies only to 4U (36000X, 3600NL, 72000X, and 72000NL) nodes): The electrical outlet is
providing sufficient AC to the power supplies, but the node is turned off.
Steady amber (applies only to all X- and S-series nodes): The electrical outlet is providing sufficient AC to the power
supplies, but the node is turned off.
Blinking amber (applies only to all X- and S-series nodes): There is a power supply failure.
Light is off (applies to all node models): There is no or insufficient AC power.

Perform the following steps:
1. If a single node reports the issue, determine the cause of the issue by performing the following steps:
a. Determine if the electrical outlet is functioning properly by plugging the power cable into a different electrical
outlet.
b. If the issue is not resolved by using a different electrical outlet, move the power cable from the power supply
that reports the failure to the power supply of a node that does not report a failure. If the cable is the issue, replace
the cable.
