您能否帮助理解并获取故障磁盘（如果有）。谢谢
答案1
是的，这个 10 Tb 磁盘（序列号为 ）ZVJ2GZSP快要坏了。我想知道为什么初始报告说它是 16 Tb。
它已经使用了保留区域中的9000多个扇区：
5 Reallocated_Sector_Ct 0x0033 098 098 010 Pre-fail Always - 9208
我认为您可以安全地将其移除，因为此 RAID 控制器上的所有存储都是冗余的（RAID1 或 RAID 10），并且全部都是最佳的。您必须将此磁盘设置为脱机。将磁盘设置为脱机后，GHS（全局热备用）之一应启动并替换其阵列中的此磁盘。
该磁盘位于机柜托架号 9 中（请记住，这些是从 0 开始的，因此它是第 10 个）。但是，为了确定，您可以使用机柜的定位功能。
详细信息请参阅控制器手册。
