10o用smartctl获取不到硬盘时间

ada1984

今天才开出来的，想看硬盘时间
raid0配置，用的命令是
smartctl -a -d cciss,0 /dev/sda
smartctl -a -d cciss,1 /dev/sda

运行以后报错误：
# smartctl -a -d cciss,0 /dev/sda
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.4.0-92-generic] (local build)

CCISS ioctl error 3 (fd -1 CDBLen 12 buf_size 16392)
Smartctl open device: /dev/sda [cciss_disk_00] [SCSI/SAT] failed: INQUIRY [SAT]:

另一台10o上就可以正常获取：
# smartctl -a -d cciss,0 /dev/sda
