• Windows server running MSSQL  and  tempDB running on snapshot/while taking snapshot, event logs report Error 823/824
• Event description of SQL server event logs states

DESCRIPTION: SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x713e0d75; actual: 0x5f1e6db3). It occurred during a read of page (5:528336) in database ID 2 at offset 0x00000101fa0000 in file 'T:\MSSQL15.MSSQLSERVER\MSSQL\Data\tempdb_mssql_4.ndf'. Additional messages in the SQL Server error log or operating system error log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online

Note:The preceding log excerpts are only examples.Date,time and environmental variables may vary depending on your environment.

To workaround this issue without powering off the VM

1. Disable the bloom filter on the ESXi host running the SQL VM by setting the config option.

     esxcli system settings advanced set -i 0 -o /SE/BFEnabled

      2. vMotion the VM to another ESXi host and back again for the changes to take affect.

NOTE: In VMware vSphere ESXi 7.0 U3f/8.0 the bloom filter is disabled.
