Applies toNetApp E-Series
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 mismatc||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.|
