配置确认
远程用户可以通过 iDRAC9 管理界面确定后部 4x2.5" 硬盘背板是否存在。转至 Storage > Overview > Enclosures。展开可用的机柜详细信息,检查是否存在 Enclosure Location = Rear。
日志警报

此外,生命周期日志可能还包含风扇 RPM 事件(FAN0000、FAN0005)和风扇冗余事件(RDU0001、RDU0002)。
2022-02-15 01:38:55 3413 RDU0001 The fans are redundant.
2022-02-15 01:38:54 3412 FAN0005 Fan 9A RPM is within range.
2022-02-15 01:38:54 3411 FAN0000 Fan 9A RPM is less than the lower warning threshold.

2022-02-15 01:38:51 3407 FAN0000 Fan 7A RPM is less than the lower warning threshold.
2022-02-15 01:38:51 3406 RDU0002 Fan redundancy is lost.
原因
iDRAC9 每五秒查询一次系统风扇的 RPM 读数。当这些事件循环快速连续发生时,iDRAC 会将某些返回的数据字节误解为错误,从而导致虚假的“removed”(已卸下)消息。
解决方案
Dell iDRAC9 固件版本 5.10.10.52(2022 年 4 月)解决了对这些返回的 RPM 响应的错误处理,建议升级到此版本。
