How to View soft and hard raid information in Centos

Software raid: you can only view cat/proc/mdstat on the Linux system to view raid level, status, and other information. Hardware raid: The best solution is to use the installed raid vendor's management tools to check whether there is a broken line or a graphical interface. For example, the hardware card of Adaptec can use the following command to view the software raid: you can only view cat/proc/mdstat through the Linux system itself to view the raid level, status, and other information. Hardware raid: The best solution is to use the installed raid vendor's management tools to check whether there is a broken line or a graphical interface. For example, the Adaptec hardware card can be viewed through the following command: #/usr/dpt/raidutil-L all can see very detailed information. Of course, in more cases, there is no corresponding management tool installed. if you only need to rely on Linux itself, I generally know two methods: # dmesg | grep-I raid # cat/proc/scsi displays similar information, such as the raid manufacturer, model, and level, but cannot view the information of each hard disk. In addition, after actual tests, Dell servers can be displayed through commands, while servers such as HP and IBM cannot be displayed through the above commands. You can only view the BMC of DELL by installing the management tools of hardware vendors.
