问题描述

HA 对中的一个节点报告读取温度传感器的问题，该问题已自动得到纠正：

[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.temp.unreadable:error]: The controller temperature (Midplane 3 Temp) is not readable. [node1: env_mgr: monitor.temp.unreadable:error]: The controller temperature (Midplane 2 Temp) is not readable. [node1: env_mgr: monitor.temp.unreadable:error]: The controller temperature (Midplane 1 Temp) is not readable. [node1: env_mgr: monitor.temp.unreadable:error]: The controller temperature (Ambient Temp) is not readable. [node1: env_mgr: callhome.c.fan.fru.fault:error]: Call home for CHASSIS FAN FRU FAILED: Multiple fans have failed [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.

受影响节点上的某些温度传感器不可用，而伙伴节点则将其报告为正常。

cluster1::> system node run -node * -command environment status 2 entries were acted on.

Node: node1

Shelf temperatures by element: [10] 28 C (82 F) Normal temperature range [11] Unavailable [12] Unavailable [13] 29 C (84 F) Normal temperature range

Node: node2

Shelf temperatures by element: [10] 33 C (91 F) Normal temperature range [11] 48 C (118 F) Normal temperature range [12] 26 C (78 F) Normal temperature range [13] 34 C (93 F) Normal temperature range

当问题仍然存在但仅来自一个节点时，FRU 状态会显示为降级：

cluster1::> system controller fru show Node FRU Name Subsystem Status ------------------ ---------------------------- ------------------ ----------- node1 PSU1 FRU Environment degraded node1 PSU2 FRU Environment degraded node2 PSU1 FRU Environment ok node2 PSU2 FRU Environment ok

受影响节点的 BMC 频繁重启并在 SP 事件日志中报告以下内容：

Record 1250: Sat Jan 28 10:04:27.990616 2023 [BMC.critical]: Rebooting SP due to loss of ACP comms Record 1251: Sun Jan 01 00:00:23.962645 2017 [IPMI.notice]: 00fd | c0 | OEM: ffff70005100 | ManufId: 150300 | BMC Reset Internally

问题发生期间对端口 e0M 进行的数据包跟踪分析显示来自集群间逻辑接口 (IC LIF) 的传入流量很高。
