What 9.1.29 means
Stored Data Integrity Failure p. 165
Common causes
- Data associated with the GC's measurement results and logs are stored in the GC along with a 16-bit cyclic redundancy check (CRC) code. When the data is retrieved, its integrity is verified by recomputing the CRC code and comparing it with the CRC code stored along with the data. p. 165
- Save the current configuration and replace the CPU board. p. 165
What to do
- If there is a mismatch, then this alarm is generated. p. 165
