● (HD400 only) Make sure that the drive drawer is properly shut by sliding it out and re-closing it firmly but carefully.
● 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 event persists, gather logs, and then contact Technical Support for additional troubleshooting. For instructions on how to
gather cluster logs, see

A sensor in the front panel of a node has exceeded the specified threshold.
Description
This event can occur intermittently without harm to the system.
Administrator action
1. Cancel or quiet the event.
2. If the event recurs, shutdown and restart the node by completing the following steps:
● Connect to the affected node through SSH or serial cable.
● Shut down the node by running the following command:
shutdown -p now
● Wait for the node to shut down, and then disconnect both power supply cables.
● Press the power button on the node to discharge any remaining stored power.
● Reconnect the power cables and then start the node.
3. (HD400 only.) Re-seat the front panel connector by checking that the ribbon cable is properly attached and properly seated.
4. (All other nodes.) Re-seat the front panel.
5. Move the front panel from a functioning node to the affected node and see if the event clears.
6. Install the front panel from the affected node on another node to determine if the problem is with the front panel or with the
node.
If the problem follows the front panel, contact Technical Support to request a new front panel.
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

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.
