Memory channels parameter is not derivable using introspection memory bank data in mistral derive parameter since format of memory slot name is not consistent on different environments. Mostly default memory channels as 4 and user can read the environment spec and update memory channels parameter for that environment. Different formats : P1-DIMMA1, A1, PROC 1 DIMM 1.

From development side this was the only bug that got tested. In case it is pushed to OSP 14, it would help understand from Franck to see if he perceives any risk or any blockers to be made part of the roadmap. Need Franck's opinion on this. Regards Vijay.
