CHW-3170: CX6 or CX7 Ethernet I/O module is reporting a "warnhigh" temperature running BMC 18.3
Issue
This issue applies to the following storage systems:
- AFF A1K, AFF A70, AFF A90, AFF C80
- ASA A1K, ASA A70, ASA A90
- FAS70, FAS90
- ONTAP reports "warning high" temperature alert events for CX6 or CX7 Ethernet I/O modules. Examples:
... [node1: env_mgr: monitor.chassisTemperature.warm:alert]: Chassis temperature is too warm: IO11 400G CX7 Temp is warning high (100 C).
... [node1: env_mgr: monitor.chassisTemperature.warm:alert]: Chassis temperature is too warm: IO8 100G CX6 Temp is warning high (100 C).
- The events are cleared but a "Call Home" AutoSupport may be triggered. Examples:
... [node1: monitor: monitor.globalStatus.critical:EMERGENCY]: Chassis temperature is too high..
... [node1: env_mgr: monitor.chassisTemperature.ok:notice]: Chassis temperature is ok.
... [node1: env_mgr: callhome.chassis.hitemp:error]: Call home for CHASSIS OVER TEMPERATURE
- Examples of BMC system event log entries:
Record ... [IPMI.notice]: 0145 | 02 | EVT: 6f02ffff | IO8_Status | Assertion Event, "Fault"
Record ... [IPMI.notice]: 0148 | 02 | EVT: ef02ffff | IO8_Status | Deassertion Event, "Fault" - system node environment sensors show example:
IO8 Status normal 61
IO8 100G CX6 Temp warnhigh 100 C
IO8 100G P1 Temp normal 63 C
IO8 100G P2 Temp normal 59 C
