CFM Service Not Found in Web UI

If the Web UI couldn't find the CFM Service, please make sure that cfm-service run and cfm-webui point to the correct cfm-service through ip address with port. The ip with port of cfm-service is default as localhost:8080, but sometimes port 8080 is alreay occupied, the real ip address makes more sense. config.yaml file under webui folder is the place to set up the connected cfm-service.

Enclosure Fans Not Run

Since most left slot on the enclosure must be populated, if the enclosure fan is not running, please check if there is a blade plug to the most left slot.

CXL Link Not Up

There are several possible reasons for this issue.

  • The first reason is server lacking of CXL support, in current phase, Only the Intel 4th gen Xeon or newer, and AMD EPYC 4th gen or newer servers support CXL, please make sure you are using the listed server brand and version.
  • Cable misorder may also cause this issue. Please check your cable connections.
  • BIOS setup unproperly is another possibility. Please check your BIOS setup.
  • Sometimes the connected blade(s) may make this trouble, you can power reset the blade(s) to see if it makes sense.

CXL Link Up But cxl.mem Not Enable

The main reason is that CXL is incompatible with the platform firmware, please contact the platform vendor.
