我们有一台存储机（文件服务器），采用 LSI Megaraid 9260-16i RAID 系统，15 块硬盘配置为 RAID5，外加一块即将更换的离线硬盘。每块硬盘都是 4TB SATA3 磁盘。最近我们发现 RAID5 中的 3 块在线硬盘发生了以下相同的“巡检读取”错误事件日志：
Code: 0x0000005f

很奇怪的是，不可修复的介质错误在三块硬盘（e0xf5/s15）、（e0xf5/s5）和（e0xf5/s12）的同一个地址 e0377d38 处出现。这导致 RAID 卡一次又一次地自动启动后台初始化。从事件日志来看，RAID 卡似乎尝试修复此错误，但总是失败。因此我暂时中止了后台初始化。
我们不太清楚为什么会出现这个问题。最近我们更换了上述三块硬盘中的两块，即（e0xf5/s5）和（e0xf5/s12），因为大约三周前原来的硬盘坏了。看来是在更换硬盘后才出现这个问题的。
有人能建议我如何解决这个问题吗？如果无法修复会有什么后果？
最后附上这三个硬盘驱动器的 -AdpAllInfo、-LDInfo 和 -PDList 列表以供进一步了解。非常感谢您的帮助。
泰和长荣
