适用场景

  • NetApp E 系列
  • SANtricity OS 11.80.1GA或更早版本
  • 脱机卷副本
  • E系列平台:EF300和EF600 
    • 卷副本问题描述仅影响使用BlockSizeProxy 的卷、这意味着这些卷是使用blockSize=512 创建的、并且这些卷来自由4 k NVMe驱动器组成的卷组/DDP。

注意:只有FC类型的系统可以通过图形用户界面选择Volume Block Size 。如果主机接口类型为iSCSI,则默认值为512 ,并且只有通过 CLI创建卷才能设置blockSize=4K

问题描述

在未清除现有脱机副本对的情况下重新启动存储后、可能会触发以下问题:

1.  由于I/O错误、卷复制操作无法启动。 

  • MEL (主要事件日志):A:5/25/24, 5:45:46 AM (05:45:46) 2719 6600 Volume copy or import operation failed - Volume vol11 <--CRITICAL
  • DQ (跟踪缓冲区日志): 05/25/24-05:45:45.060 CopyProxy 0000c002 failing volume copy - Background copy I/O error - 0x208

 2.主机无法访问副本对关系中的一个或两个卷、例如VMware主机的SAN启动失败。 

 3.  如果起始卷副本从目标卷复制 到源卷、则控制器会由于以下断言而进入锁定状态、并使用有限的符号。
