[civanch]

In the PR #43576 a production of ZDC hits is enabled, which make a problem for hlt_mc_HIon addOn test. Temporary ZDC hits are masked until the problem will be solved.

I am currently seeing a similar problem running the HI workflow in latest CMSSW_14_1_X IB:

An exception of category 'Conditions not found' occurred while
[0] Processing Event run: 1 lumi: 1 event: 33 stream: 0
[1] Running path 'HLTAnalyzerEndpath'
[2] Prefetching for module L1TRawToDigi/'hltGtStage2Digis'
[3] Prefetching for module RawDataCollectorByLabel/'rawDataCollector'
[4] Prefetching for module SiStripDigiToRawModule/'SiStripDigiToRaw'
[5] Calling method for module MixingModule/'mix'
Exception Message:
Unavailable Conditions of type HcalMCParams for cell (0x54000140) (Det 5:5 subdet 2:2 ZDC+ UNKNOWN 0,0)

To reproduce the problem I did:

cd CMSSW_14_1_X_2024-03-29-1100/src/

@cms-sw/hcal-dpg-l2 FYI

This is to explicitly include Sunanda ( @bsunanda ).
Since Nov.2023 there is a new HcalZDCDetId definition for Run3
Which is not yet used (due to some issues) neither for the Geometry initialization nor for DB conditions (to add new Run3 ZDC channels). Should be fixed soon, as was discussed elsewhere (email, HCAL DPG meeting).

Commenting here to flag that experts from HCAL and ZDC side are aware (as flagged above by @abdoulline, @bsunanda) and are still working towards a solution.
