Ssd disks seem to use scsi interfaces, so they cannot be determined based on the drive letter name. At last, eric told the lsscsi tool in the group that it was very simple and displayed directly. The result is as follows: [root @ FWD_YF_009_110 ~] # Lsscsi [0: 0: 0: 0] disk SEAGATE ST3300657SS ES62-[0: 0: 1: 0] disk ata intel SSDSA2CW16 0362/dev/sda [0: 0: 0: 2: 0] disk ata intel SSDSA2CW16 0362/dev/sdb [0: 0: 3: 0] disk ata intel SSDSA2CW16 0362/dev/sdc [0: 1: 0: 0] disk Dell virtual disk 1028/dev/sdd [3: 0: 0: 0] cd/dvd TEAC DVD-ROM R.2A/dev/sr0
