CONTAP-348855：特定的 NetApp 平台可能会遇到间歇性读取校验和错误或控制器中断。

问题描述

在极少数情况下，在从平台 A1K、A70 和 A90 的 NVMe 命名空间或 NetApp FCP 或 iSCSI LUN 上托管的数据进行特定块的第一次读取操作期间，ONTAP 可能会提供错误的用户数据。
如果使用基于 ONTAP 的迁移从打开了传统压缩的平台将数据迁移到上述平台，则相同的缺陷可能会导致控制器中断。
签名示例：

• Windows 崩溃，BSOD 引用页入 CRC 违规：

Bug Check: 0x0000001a Parameter1: 0x3f

• Oracle alertlog 报告的序列类似于：

Corrupt block relative dba: 0x0000c4cd (file 42, block 50381)   Reread (file 42, block 50381) found valid data Repaired corruption at (file 42, block 50381)  

• mongo DB 报告以下序列：

对同一逻辑块地址的后续读取应成功，且未报告错误。
此问题适用于运行 9.15.1 及更高版本的上述平台的 AFF 和 ASA 变体。
运行 9.16.1RC1 及更高版本的系统未因此问题而受到影响。
