适用场景

  • StorageGRID设备SG6060
  • StoageGRID设备的E系列控制器E2800

问题描述

Auto Support为驱动器隔离打开了案例、从而导致冗余不匹配。
 
E系列阵列中的主要事件日志显示即将发生的驱动器先前已触发到保留容量的驱动器副本。

B:5/22/23, 7:48:36 PM (19:48:36) 5208 3803 Disk pool reconstruction reserved drive count is below threshold - Disk Pool StorageGRID-disk-pool99 <--CRITICAL
B:5/22/23, 7:48:36 PM (19:48:36) 5207 227e Drive copy started - Shelf 99, Drawer 4, Bay 5
A:5/22/23, 7:48:36 PM (19:48:36) 5206 3803 Disk pool reconstruction reserved drive count is below threshold - Disk Pool StorageGRID-disk-pool99 <--CRITICAL

后来、驱动器出现故障并更换了POST、错误数据复制回新磁盘、E系列将驱动器隔离、以避免冗余不匹配。
