Degradation Operations
This chapter provides detailed information about suspect and degraded data. Data is considered suspect if one or more copies of the data is corrupt (if the checksum read does not match the expected value). Data is considered degraded if it is manually marked as lost (for example, if an ejected tape that contains a copy is marked as permanently lost) or if suspect data is manually marked as degraded. Degraded data can still be read provided that at least one copy of the data is good. If every copy of copy of the data is marked as degraded, this eliminates your ability to GET or VERIFY the object.
