●
Review the temperature statistics for the affected sensor, which are included in the event. If the temperature is consistently
elevated, the problem is likely a high ambient temperature in the data center. Address any changes in the cluster
environment such as air conditioning outages.
●
Verify that air flow within the rack, and through the front and rear panel vents of the node, is not obstructed in any way.
●
Make sure that the faceplate on the affected node is installed, properly seated, and undamaged. In some cases, removing
and re-seating the faceplate will resolve this issue.
●
Run the
isi_hw_status
command. Review the output to determine whether there is a slow or failed fan that was not
otherwise reported.
●
Check for high CPU and disk usage in the node. High usage can contribute to high temperatures within the node.
If the steps above were unsuccessful in clearing this event, the subsystem that monitors the health of the hardware (such as
the temperature and fan speeds) might have encountered a problem. This event can occur intermittently without harm to the
system and you can safely quiet the event unless the issue persists.
If the above steps do not resolve the issue, gather logs, and then contact Technical Support for additional troubleshooting. For
instructions on how to gather cluster logs, see

There are multiple power supply issues that might cause this event to occur.
Administrator action
1. If the event message specifies an issue with the power supply temperature, verify that the ambient temperature where the
cluster is located has not exceeded the specifications.
2. If the event message specifies any other power supply input issue, verify that your power source is functional.
If the event persists, gather logs, and then contact Technical Support for additional troubleshooting. For instructions on how to
gather cluster logs, see

900150001
The node is reporting less than the expected amount of physical memory.
Description
This event typically appears because a DIMM has failed, is poorly seated, or an incorrect type of DIMM is installed.
Administrator action
Contact Technical Support to determine if a DIMM replacement is required.
900160001
A node is not connected to its peer node.
Description
When a node is disconnected from its peer node, the node journals are not mirrored and data is at risk. The event message
provides you with the chassis and node slot where the disconnected node is located.
