问题描述
华为存储的iBMC（智能基板管理控制器）日志体系庞大，与硬盘故障相关的信息主要记录在硬件故障类、存储类以及系统运行类的日志中。
以下是定位坏盘信息时可以重点检查的日志文件和常用命令：
关键日志文件
日志文件 所属类别 作用与关键字
sel.db / sel.tar 硬件故障类记录所有硬件事件，是定位坏盘的核心日志。可查找Asserted（告警触发）和Deasserted（告警解除）等关键字。
current_event.txt
硬件故障类记录当前未清除的告警，可查找 Critical（严重）或Major（重要）等关键字。
RAID_Controller_Info.txt存储类记录RAID卡状态。可查找 Degraded（阵列降级）、Offline（磁盘离线）和 Rebuild（重建中）等关键字。
StorageMgnt_dfl.log存储类记录存储管理相关事件，可查找 comm lost（通信中断）等关键字，这可能意味着硬盘或链路故障。
BMC_dfl.log系统运行类记录BMC核心异常，有时硬盘问题会引发系统级报错，可查找 exception（异常）或 watchdog（看门狗超时）等关键字。
常用诊断命令
除了直接查看日志文件，在BMC命令行界面使用特定命令可以更高效地获取硬盘状态：
bm show disk: 显示基本磁盘信息。
bm show faultdiskio: 专门用于显示故障磁盘的I/O信息。
bm show framediskinfo: 显示背板磁盘信息。
bm blockcheck: 执行块检查，可用于诊断坏块。
showlog: 通用的日志查询命令，可以筛选查看BMC日志。
bdm_interbiglog_collect.sh: 用于收集硬盘内部的详细日志信息。
过程分析
