| Enable tracedebug for Client nodes (ISM) | If advised by Hitachi support same procedure may be used for the Master node. |
| 1. /opt/hitachi/protector/bin/diagdata --stop all | Not required, but may help with the troubleshooting, and will free up more space when step 2 is executed. |
| 2. /opt/hitachi/protector/bin/diagdata -p | Purge existing logs to free up space. If application is running you may receive warning some files could not be deleted, this is expected. |
| 3. /opt/hitachi/protector/bin/diagdata -t tracedebug | Increase the trace level. |
| Do you also want to change the trace level for processes already running? [Y/n]: Y | When this message appears. Respond Y. |
| 4. /opt/hitachi/protector/bin/diagdata --start all | Not required if Protector was not stopped in step 1. |
| 5. Recreate the problem. | |
| Reset trace level and collect logs for Client nodes (ISM) | |
| 6. /opt/hitachi/protector/bin/diagdata -t tracealways | Set trace level back to tracealways. |
| Do you also want to change the trace level for processes already running? [Y/n]: Y | When this message appears. Respond Y. |
| 7. /opt/hitachi/protector/bin/diagdata -f | Export logs. Logs will be stored in /opt/hitachi/protector/runtime/diag*.zip. |
| 8. /opt/hitachi/protector/bin/diagdata --stop all | Not required, but will free up more space when step 8 is executed. |
