方法1：通过cat/sys/block/sda/queue/rotative查看/sys/block/sda/queet/rotative，返回值0为SSD；返回1表示HDD。方法2：通过lsscsi[root@ssd-testthatsit]#cat/sys/bl
方法
法1：通过查看/sys/block/sda/queue/rotational
通过cat /sys/block/sda/queue/rotational进行查看，返回值0即为SSD；返回1即为HDD。
法2：通过lsscsi查看
lsscsi - list SCSI devices (or hosts) and their attributes
