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).
