Current Issues with Back-end.
List of issues we observed during local data taking relative to the Back - End.
NOTICE!!! The dpm numbers in the daq map after 7 are off by one. Example: DataDpm[13] in the DAQ MAp is hostname dpm14.
1)
| RCE | Data path | Issue |
|---|---|---|
| Dpm[6] | 0 | Feb3 (L2-3b) connected. Observed timeout waiting for data. Observed TriggersOut lagging wrt TriggerIn during local data taking (96 vs 891 expected). Doesn't lose sync. |
| Dpm[6] | 1 | Feb3 (L2-3) connected. SampleExtractor shows triggers out lagging wrt Trigger In. Doesn't lose sync. |
Attempts to diagnose the error:
- Swap fiber H with F (changes channels in the RTM).
- Reset COBs to change DaqMap
