E-Series Data Integrity Related Events
Applies to
NetApp E-Series
Answer
If data corruption is suspected at the application layer, it is entirely possible that nothing will be recorded in the controller logs. It is appropriate to validate RAID/Parity if this occurs.
E-Series Data Integrity-Related Events:
Event Description | Event ID | Event Details |
Data/parity mismatch on volume | 200A |
A data/parity mismatch is detected during data scrubbing (media scan) on a volume. For RAID 1 configuration, it indicates there is a mismatch between the two mirror data copies. |
Isolation and correction of redundancy mismatch | 2041 |
A redundancy (data/parity) mismatch has been isolated to a single drive. This level of isolation is only possible with RAID 6 and Dynamic Disk Pool due to the presence of dual parity. |
Data assurance mismatch detected - probable cause is cached data | 2061 |
A cached volume data and protection information do not match. |
Data assurance mismatch detected - probable cause is data on drive | 2062 | Data returned from drive and protection information do not match. |
Data assurance mismatch detected - probable cause is channel interface | 2060 | A channel interface and protection information do not match. |
