Instructions

  1. Confirm what hardware the alerted node is.

    For Gen 1/2 nodes, respond to the form in the email that assistance is required. For Gen 3 nodes, follow the rest of this kb.

  2. Check the current status of the temperature sensors. Below we see "CRIT" on two of the nodes indicating problems on those two nodes. If all nodes report as "OK" but this alert has been received this alert multiple times recently, then it could be a recurring issue. If so, respond to the form in the email that assistance is required with a recurring temperature alert.

    admin@node1:~> viprexec -i  cs_hal sensors temp

    If multiple nodes are reported as not "OK," then it is possibly an issue within the environment of your data center. Check that there are no issues in the area in which the ECS is located that might be increasing the ECS temperature.

  3. Check the status of the ECS fans.

    admin@ecs:~>cs_hal sensors fan

System Board      Fan                 Fan Redundancy    OK      fully redundant;

NOTE: on Axum and EX-series, use "sudo -i racadm getsensorinfo" to obtain sensor information.

  4. Respond to the form in the email that assistance is required, including both the temperature sensor outputs and the fan outputs.
