sas硬盘查看健康度记录raid卡直通看不到SMART信息

硬盘出现坏块，全盘扫描之后修复了，想看看还不能用

由于是raid卡直通的，一般软件看不到，下载 smartmontools-7.5.win32-setup ，地址在www.smartmontools.org，或者https://sourceforge.net/projects/smartmontools/。

 

smartctl --scan

在结果里面选择盘：
# 如果是 LSI Megaraid 卡:
smartctl -a -d megaraid,0 /dev/sda

# 如果是普通的 SAS/SCSI 直通模式:
smartctl -a /dev/sdb

信息给ai看了说不能用了，随时可能挂：

C:\Users\Administrator>smartctl -a /dev/sde
