FreeBSD下SLI卡下硬盘的检测

1、安装smartmontools，用ports最简单了。
2、在默认的状态下，接在sli卡下磁盘的名称为mfisyspd0，此时直接用smartctl 命令，则不认识磁盘：

smartctl -a /dev/mfisyspd2
smartctl 6.1 2013-03-16 r3800 [FreeBSD 9.1-STABLE amd64] (local build)

/dev/mfisyspd2: Unable to detect device type
Please specify device type with the -d option.

Use smartctl -h to get a usage summary

3、需要对这些磁盘做一些映射，加载mfip模块：

#kldload mfip
#kldstat
Id Refs Address Size Name
 1 13 0xffffffff80200000 a0a268 kernel
 2 1 0xffffffff80e19000 d19 mfip.ko

4、在/dev/就会产生一些pass，要注意看这些pass，光驱会占掉一个，比如下面，有三块硬盘，依次是pass1-pass3

# ls /dev/pass*
/dev/pass0 /dev/pass1 /dev/pass2 /dev/pass3

5、对pass1-3再实行smartctl ，就可以看到磁盘信息了：

# smartctl -a /dev/pass2
smartctl 6.1 2013-03-16 r3800 [FreeBSD 9.1-STABLE amd64] (local build)
