SMART Error Log Version: 1

Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.
Error 912 occurred at disk power-on lifetime: 0 hours (0 days + 0 hours)

SMART Self-test log structure revision number 1
No self-tests have been logged. [To run self-tests, use: smartctl -t]
SMART Selective self-test log data structure revision number 0
Note: revision number not 1 implies that no selective self-test has ever been run
SPAN MIN_LBA MAX_LBA CURRENT_TEST_STATUS
1 0 0 Completed [00% left] (0-65535)
2 0 0 Not_testing
3 0 0 Not_testing
4 0 0 Not_testing
5 0 0 Not_testing
Selective self-test flags (0x0):
After scanning selected spans, do NOT read-scan remainder of disk.
If Selective self-test is pending on power-up, resume after 0 minute delay.
如果有RAID则smartctl将不起作用了，需要查看raid信息，使用对应厂家提供的工具
[root@appsvr etc]# dmesg | grep -i raid

在这里看到使用了LSI的卡，也可以使用如下命令RAID信息但是没有dmesg完整。
