You might want to run the data consistency test after replacing a drive in a Drive Enclosure. Also, Oracle Customer Support might request that you run a data consistency test for diagnostic purposes.
High priority: The verification check could affect I/O performance by up to 30%. The high‑priority option yields faster results, but has a greater impact on system performance.
Low priority: The verification check could affect I/O performance by up to 10%. The low‑priority option is recommended if you want to check the Drive Enclosure after replacing a drive.
Data consistency failures are typically isolated to the drive or drive group error handling. The Oracle FS System compensates for some of the errors that are encountered during the tests. However, if an error persists that cannot be fixed, the system displays Fail on the Data Consistency overview page. In this case, collect the Oracle FS System data logs and contact Oracle Customer Support.
