raid.tetris.cksum.bno
- Severity
-
NOTICE
- Description
-
This message occurs when the system detects a block number mismatch during a write operation. The expected Virtual Block Number (VBN)/Disk Block Number (DBN) is not the same as the stored VBN/DBN from the checksum entry indicating that the block is read from the wrong location. Data ONTAP® makes appropriate recovery actions. Other events describe those actions.
- Corrective Action
-
(None).
- Syslog Message
-
Block number mismatch on %s%s: stored_dbn = %u, expected_dbn = %llu; stored_vbn = %llu, expected_vbn = %llu during write operation.
