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：

1. smartctl -a /dev/mfisyspd2
2. smartctl 6.1 2013-03-16 r3800 [FreeBSD 9.1-STABLE amd64] (local build)
3. Copyright (C) 2002-13, Bruce Allen, Christian Franke, www.smartmontools.org
4. /dev/mfisyspd2: Unable to detect device type
5. Please specify device type with the -d option.
6. 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：

1. #kldload mfip
2. #kldstat
3. Id Refs Address Size Name
4. 1 13 0xffffffff80200000 a0a268 kernel
5. 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

1. # ls /dev/pass*
2. /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：

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