2.3.2. 安装系统(使用CentOS Linux 7.9举例)所需要的smartmontools

 

yum install -y smartmontools

2.3.3. 通过smartctl 查询LSI阵列卡中磁盘的DID（Drive ID）信息

 

输入：

 

# smartctl --scan

 

输出：

 

/dev/sda -d scsi # /dev/sda, SCSI device # 呈现在系统中的阵列逻辑盘

/dev/sdb -d scsi # /dev/sdb, SCSI device # 呈现在系统中的阵列逻辑盘

/dev/bus/0 -d megaraid,14 # /dev/bus/0 [megaraid_disk_14], SCSI device # 对比上面的阵列信息，有"megaraid"字样的，都是阵列卡的成员盘

/dev/bus/0 -d megaraid,15 # /dev/bus/0 [megaraid_disk_15], SCSI device # '''

/dev/bus/0 -d megaraid,16 # /dev/bus/0 [megaraid_disk_16], SCSI device # '''

/dev/bus/0 -d megaraid,17 # /dev/bus/0 [megaraid_disk_17], SCSI device # '''

/dev/nvme0 -d nvme # /dev/nvme0, NVMe device # 这通主板的NVMe磁盘

2.3.4. 查看阵列中一块磁盘的smart信息（不同品牌硬盘，或者不同型号硬盘都可能产生"Vendor Specific SMART Attributes with Thresholds"输出有所不同）
