适用于

  • NetApp E 系列
  • NetApp StorageGRID 设备

事件摘要

  • E-Series 缓存备份设备容量不足表示控制器板载 mSATA 备份设备可能未通过诊断测试,导致备份容量不足。
  • 每当持久缓存备份设备的可用容量小于缓存内存的可用容量时,所有卷都将更改为直写缓存。 
    • 这将生成一个恢复失败条目,说明缓存备份设备容量不足。
    • 配置为允许在没有电池的情况下进行写缓存的卷将不受影响。

验证

  1. 打开 SANtricity System Manager 并查看主页下的恢复专家失败条目列表。
  2. 在 SANtricity System Manager 中,可以在硬件部分或支持"支持资源"部分的存储阵列配置文件下检查缓存备份设备状态。
