my system has two BMCs , I need to switch the json configure files to provide two different SDR list. below is my solution:
under the entity-manager I prepared two json files(A/B) to dynamically replace BMCsensor_2U.json when the in Slot A or B
json files has been burnd to flash and can be found:
when in Slot A:
cp BMCsensor_2U_A.json BMCsensor_2U.json -af
change something to /etc/os-release let the json file fully reloaded.
systemctl restart xyz.openbmc_project.EntityManager.service
when in Slot B:
cp BMCsensor_2U_B.json BMCsensor_2U.json -af
change something to /etc/os-release let the json file fully reloaded.
systemctl restart xyz.openbmc_project.EntityManager.service
the issue I observed:
sometimes the BMCsensor_2U.json can not be replaced and can not be removed, reported "stale handle" even I stopped xyz.openbmc_project.EntityManager.service
sometimes BMCsensor_2U.json can be replaced by A or B, but ipmitool sdr list is still kept old.
my question: is my solution reasonable? or is it a known issue?
