在rhel6.3 x86-64系统上安装lsscsi包

本文是原创文章，转载请注明出处：http://blog.csdn.net/msdnchina/article/details/43637889

lsscsi包默认是不安装的。lsscsi包安装完之后，lsscsi命令就可以使用了。

lsscsi命令（lsscsi -t）能很方便的看出哪些是固态硬盘（SSD），哪些是SATA盘，哪些是FC盘。

关于lsscsi命令的详细使用说明，请见：http://blog.csdn.net/msdnchina/article/details/43638857

/usr/bin/which: no lsscsi in (/usr/lib64/qt-3.3/bin:/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin:/root/bin)
--->我本来的推测是安装了iscsi包之后，lsscsi命令就能看到了，其实从上面的输出可以看出不是这样的。
