COTTP-348855：在特定NetApp平台上的LUN或NVMe命名空间中托管时、SAN连接的主机可能会出现间歇性读取校验和验证错误

问题描述

在极少数情况下、对平台A1K、A70和A90上托管在NVMe命名空间或NetApp FCP或iSCSI LUN上的数据中的特定块执行第一次读取操作时、ONTAP可能会提供错误的用户数据。
签名示例：

• Windows崩溃、BSOD引用页面进入CRC违规：

Bug Check: 0x0000001a Parameter1: 0x3f

• Oracle alertlog报告的顺序类似于：

Corrupt block relative dba: 0x0000c4cd (file 42, block 50381)  
Reread (file 42, block 50381) found valid data
Repaired corruption at (file 42, block 50381)  
MSSQL日志报告类似以下内容的错误：

• 
  A read of the file 'D:\path\file.mdf' at offset 0x0000006d70a000 succeeded after failing 1 time(s) with error: torn page (expected signature: 0x00000000; actual signature: 0x00c03444). Additional messages in the SQL Server error log and operating system error log may provide more detail. This error condition threatens database integrity and must be corrected. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.

Additional messages in the SQL Server error log and operating system error log may provide more detail. This error condition threatens database integrity and must be corrected.

  A read of the file 'D:\path_toe\system.mdf' at offset 0x0000006d70e000 succeeded after failing 1 time(s) with error: incorrect pageid (expected 1:224135; actual 27267:-1332691384). Additional messages in the SQL Server error log and operating system error log may provide more detail. This error condition threatens database integrity and must be corrected.

随后读取同一逻辑块地址应成功、并且不会报告任何错误。
