戴尔R720xd上的MegaCli和PERC H710P上的5个4Tb SATA驱动器在RAID5中出现奇怪的SMART错误
/opt/MegaRAID/MegaCli/MegaCli64 -PDList -aALL 给我一些“失败次序事件编号”
Slot Number: 4 ... Last Predictive Failure Event Seq Number: 7309 ... Inquiry Data: PK2361PAGAZU8WHitachi HUS724040ALE640 MJAOA3B0 ... Drive has flagged a SMART alert : Yes
但smartctl根本没有提供线索有什么问题：
# smartctl -a -d sat+megaraid,4 /dev/sda smartctl 5.42 2011-10-20 r3458 [x86_64-linux-2.6.32-279.19.1.el6.x86_64] (local build) ... Serial Number: PK2361PAGAZU8W # Note same serial, no mistake ...

没有理由在上面皱眉
做了短暂的自测并没有透露任何东西，现在开始长时间的testing：
Serial Number: PK2331PAG7EENT SMART Self-test log structure revision number 1 Num Test_Description Status Remaining LifeTime(hours) LBA_of_first_error # 1 Short offline Completed without error 00% 4911 -
同时，同一arrays中有39个磁盘重新分配扇区，PERC不会将其标记为即将失败。 smartctl输出如下：
Serial Number: PK2331PAG7EENT ... ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 5 Reallocated_Sector_Ct 0x0033 100 100 005 Pre-fail Always - 39
和MegaCli64输出为39个重新分配的部门相同的磁盘：
Slot Number: 0 Last Predictive Failure Event Seq Number: 0 Inquiry Data: PK2331PAG7EENTHitachi HUS724040ALE640 MJAOA3B0 ... Drive has flagged a SMART alert : No
MegaRAID存储pipe理器的报告也不是很有启发性：
ID = 113 SEQUENCE NUMBER = 7310 TIME = 11-07-2013 20:58:01 LOCALIZED MESSAGE = Controller ID: 0 Unexpected sense: PD = -:-:4Hardware impending failure general hard drive failure, CDB = 0x03 0x00 0x00 0x00 0x40 0x00 , Sense = 0xf0 0x00 0x00 0x00 0x00 0x00 0x00 0x0a 0x00 0x00 0x00 0x00 0x5d 0x10 0x00 0x00 0x00 0x00 ID = 96 SEQUENCE NUMBER = 7309 TIME = 11-07-2013 20:58:01 LOCALIZED MESSAGE = Controller ID: 0 PD Predictive failure: -:-:4
所以磁盘似乎是健康的，任何想法如何重置SMART警报？ 我不认为聪明的统计数据足以要求保修。
PS：我们已经取消了＃4，插上了＃5，显示健康，显示为预期的“外国”，现在被指定为全球热点。 放置新驱动器＃4和RAID重build音量。 戴尔支持build议使用omconfig来获取更详细的控制器日志。
