Data validation for storage pools allows the server to validate that data sent to a device during a write operation matches what the server later reads.
Data validation is helpful if you introduce new hardware devices. The validation assures that the data is not corrupted as it moves through the hardware, and then is written to the volume in the storage pool. You can use the DEFINE STGPOOL or UPDATE STGPOOL commands to enable data validation for storage pools.
When you enable data validation for an existing storage pool, the server validates data that is written from that time forward. The server does not validate existing data which was written to the storage pool before data validation was enabled.
Check the activity log for details about the audit operation.
The server removes the CRC values before it returns the data to the client node.
