Applies to

  • ONTAP 9
  • Motherboard (MB)

Issue

  • One node reporting ONTAP event messages due to operating outside of normal temperature.

Example:

[node_name-2: env_mgr: monitor.chassisTemperature.warm:alert]: Chassis temperature is too warm: Bat Ambient 2 is warning high (42 C).
[node_name-2: env_mgr: monitor.chassisTemperature.warm:alert]: Chassis temperature is too warm: Bat Ambient 1 is warning high (42 C).
[node_name-2: monitor: monitor.globalStatus.critical:EMERGENCY]: Chassis temperature is too high..
[node_name-2: env_mgr: callhome.chassis.hitemp:error]: Call home for CHASSIS OVER TEMPERATURE
[node_name-2: env_mgr: monitor.temp.unreadable:error]: The controller temperature (RiserM LTemp2) is not readable
[node_name-2: env_mgr: monitor.temp.unreadable:error]: The controller temperature (RiserM RTemp1) is not readable.

  • Partner node reports the same temperature ONTAP event messages.

Example:

[node_name-1: env_mgr: monitor.shutdown.chassisOverTemp:EMERGENCY]: Chassis temperature is too hot: Multiple Temp sensors are too high. System will be shutdown in 2 minutes
[node_name-1: env_mgr: callhome.chassis.overtemp:EMERGENCY]: Call home for CHASSIS OVER TEMPERATURE SHUTDOWN
[node_name-1: env_mgr: monitor.shutdown.emergency:EMERGENCY]: Emergency shutdown: Environmental Reason Shutdown (Temperature critical)

  • Node unable to boot with.

Example:

Boot Loader version 6.6.4

Portions Copyright (C) 2002-2022 NetApp, Inc. All Rights Reserved.
ACPI RSDP Found at 0x6f7fe014
BIOS POST Failure(s) detected: PCIe device missing error detected. Abort AUTOBOOT

  • BMC events for that node:

Example:

Record 2486: Fri Jan 19 05:50:28.000000 2024 [SysFW.notice]: Device 47/0/0 (SW0-VS1-P40) missing
Record 2487: Fri Jan 19 05:50:28.000000 2024 [SysFW.notice]: Device 74/0/0 (SW0-VS0-P32) missing
Record 2488: Fri Jan 19 05:50:43.000000 2024 [Boot Loader.critical]: Abort Autoboot due to BIOS POST failure.
