This article mainly introduces "how to view Raid disk array information in linux". In daily operation, I believe many people have doubts about how to view Raid disk array information in linux. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubt of "how to view Raid disk array information in linux". Next, please follow the editor to study!

The method of viewing soft and hard raid information under Linux.

Software raid: can only be viewed through the Linux system itself

Cat / proc/mdstat

You can see the raid level, status and other information.

Hardware raid: the best way is to view it through the installed raid vendor's management tools, including cmdline and a graphical interface. For example, the hardware card of Adaptec can be viewed by the following command:

# / usr/dpt/raidutil-L all

You can see very detailed information.

Of course, more often than not, there are no corresponding management tools installed, so we can only rely on Linux itself. Generally speaking, there are two ways I know:

# dmesg | grep-I raid

# cat / proc/scsi/scsi

The information displayed is about the same, raid manufacturer, model, level, but can not view the information of each hard drive.

In addition, after the actual test, the server of Dell can be displayed through the command, while the server of HP, IBM and so on can not be displayed by the command above. DELL can only be viewed by installing the hardware manufacturer's management tools. BMC can be viewed.

Cat / proc/scsi/scsi

You can see that it is a device on the SCSI. You can generally see the RAID level. Lspci can see the model of the raid card.
