12/14: QE has been enabled with 2WPC testing , This should get verified soon
In a SNO with 2 WPC cards, where the ens2f is connected to GPS and ens7f is connected to ens2f through SMA1.
pins: "ens2f0": "U.FL2": "0 2" "U.FL1": "0 1" "SMA2": "0 2" "SMA1": "2 1" "ens7f0": "U.FL2": "0 2" "U.FL1": "0 1" "SMA2": "0 2" "SMA1": "1 1"
Test Steps:
1. Wait for GM is locked and openshift_ptp_clock_state for all the processes are locked
# HELP openshift_ptp_clock_state 0 = FREERUN, 1 = LOCKED, 2 = HOLDOVER
# TYPE openshift_ptp_clock_state gauge
openshift_ptp_clock_state{iface="CLOCK_REALTIME",node="cnfde21.ptp.lab.eng.bos.redhat.com",process="phc2sys"} 1
openshift_ptp_clock_state{iface="ens2fx",node="cnfde21.ptp.lab.eng.bos.redhat.com",process="GM"} 1
openshift_ptp_clock_state{iface="ens2fx",node="cnfde21.ptp.lab.eng.bos.redhat.com",process="dpll"} 1
openshift_ptp_clock_state{iface="ens2fx",node="cnfde21.ptp.lab.eng.bos.redhat.com",process="gnss"} 1
openshift_ptp_clock_state{iface="ens2fx",node="cnfde21.ptp.lab.eng.bos.redhat.com",process="ts2phc"} 1
openshift_ptp_clock_state{iface="ens7fx",node="cnfde21.ptp.lab.eng.bos.redhat.com",process="dpll"} 1
openshift_ptp_clock_state{iface="ens7fx",node="cnfde21.ptp.lab.eng.bos.redhat.com",process="ts2phc"} 1
2. Manually disconnect the 1PPS connection between 2 cards by disabling SMA1 on card ens7f.
echo 0 1 > /sys/class/net/ens7f0/device/ptp/ptp*/pins/SMA1
The dpll and GM should immediately goes to FREERUN in the metrics

3. Reconnect the 1PPS connection. Wait for a while until GM and dpll states all go back to 1 (LOCKED).
echo 1 1 > /sys/class/net/ens7f0/device/ptp/ptp*/pins/SMA1
Actual Result:
After repeating the tests 1-6 times, the GM state stays at locked while dpll changed to 0, and it stays like this for a very long time.

Reproducible:
The issue is seen after repeating the test successfully 1-6 times.
