View hard drive model, size, and other information (including RAID) under Linux

Linux under View hard disk model, size and other information, the machine does not have a raid relationship

One, Normal mode (the drive does not do disk array)

1, fdisk-l view your hard drive number, such as SDA,SDB, etc.

2, Smartctl--ALL/DEV/SDA

Smartctl--ALL/DEV/SDA #该命令centos自带

As can be seen from the above, the hard drive model is SanDisk sd6sb1m128g1022i with a capacity of 128GB

Second, disk array raid mode

If the machine has a disk array, then running the above command will error, not get the disk information you want. You can use the MEGACLI command

MEGACLI command system does not own, need additional download,
