注意：如有提示命令找不到command not found，请自行安装所需命令。
1、lshw查看所有硬件摘要信息
下面命令可以查看所有硬件摘要信息，并输出成一个html文件，把此html文件导出到电脑上，直接打开，可以清楚的看到硬件信息：
[root@localhost /]# lshw -html > /hardware.html |
2、lsscsi查看SCSI控制器设备的信息
可以看到Raid卡信息和所有虚拟磁盘以及光驱的信息，如果没有硬件SCSI控制器，那就不会返回信息：
[root@localhost /]# lsscsi [0:2:0:0] disk DELL PERC H730P Mini 4.27 /dev/sda [0:2:1:0] disk DELL PERC H730P Mini 4.27 /dev/sdb [0:2:2:0] disk DELL PERC H730P Mini 4.27 /dev/sdc [10:0:0:0] cd/dvd PLDS DVD+-RW DS-8ABSH LD51 /dev/sr0 |
