環境

  • ONTAP 9
  • FAS 26xxシリーズ
  • FAS 27xxシリーズ

問題

  • HA ペアの 1 つのノードが温度センサーの読み取りに関する問題を報告しますが、これは自動的に修正されます。

[node1: env_mgr: monitor.fan.warning:notice]: multiple fans have failed. Replace it to avoid overheating
[node1: env_mgr: monitor.temp.unreadable:error]: The controller temperature (Module B Expander Temp) is not readable.
[node1: env_mgr: monitor.temp.unreadable:error]: The controller temperature (Module A Expander Temp) is not readable.
[node1: env_mgr: monitor.temp.unreadable:error]: The controller temperature (Midplane 4 Temp) is not readable.

[node1: env_mgr: monitor.fan.ok:notice]: All fans are OK.
[node1: env_mgr: monitor.chassisTemperature.ok:notice]: Chassis temperature is ok.
[node1: monitor: monitor.globalStatus.ok:notice]: The system's global status is normal.

  • 影響を受けるノードでは特定の温度センサーが使用できなくなりますが、パートナー ノードでは正常であると報告されます。

      [13] 34 C (93 F)  Normal temperature range

  • 問題がアクティブな場合、FRU ステータスは低下として表示されますが、これは 1 つのノードからのみ発生します。

cluster1::> system controller fru show
Node         FRU Name            Subsystem      Status

node1         PSU2 FRU            Environment     degraded
node2         PSU1 FRU            Environment     ok
node2         PSU2 FRU            Environment     ok

  • 影響を受けるノードの BMC は頻繁に再起動し、SP イベント ログに次のメッセージが報告されます。
