Read integrity checks (CLI)
Disk scrubbing (software)
While writing data, checksums are created and stored as part of the inline deduplication process. When one of the underlying layers detects data corruption, a checksum comparison is performed and when required, another copy of the data is used to repair the corrupted copy in order to stay compliant with the configured protection level.

Read integrity checks can be enabled through the CLI.

Disk Scrubbing, termed "RAID Patrol" by HPE SimpliVity 380, is a background process that is used to perform checksum comparisons of all data stored within the solution. This way stale data is also verified for corruption.
