Symptom: Unless a process restart is performed on fiarsp for ACTIVE RSP/RPi, normally RSP0/RPi0 and the RSP/RPi fia ASIC fsm is in the "SELF TEST RDY" state the user will likely be oblivious to the issue as there is no immediate or obvious functionality impact. However if a process restart of fiarsp is performed, with FIA fsm parked as mentioned, then online diags pfm alarms for fabric punt data path failure or other punt path/control plan related issues maybe observed. Conditions: following a chassis reload/bootup (admin reload loc all) of a dual RSP3/RPi (HA) system. On active RSP3/RPi run fiarsp -i0 -s fsmtrail look at ASIC state for the FWDING -> SELF TEST RDY state transition. fiarsp(fia=skt fia#=0, slot=4)>fsmtrail FSM TRAIL (FIA = 0) _____________________________________ ASIC STATE FSM TRAIL: TIME TRANSITION-2-STATE XTRNAL EVENT Jan 1 00:01:35.101 SEED_FSM to CHIP INIT FSM_KICKSTART Jan 1 00:01:37.516 CHIP INIT to LINKTRAIN RDY FMLMSG_FMTOFIA_SET_CFG Jan 1 00:01:38.621 LINKTRAIN RDY to SELF TEST RDY FMLMSG_CMN_FMTODRVR_CHSYNC_PHASE3 Jan 1 00:01:38.774 SELF TEST RDY to TRAFFIC RDY FMLMSG_FMTOFIA_RUN_SELFTEST Jan 1 00:01:38.776 TRAFFIC RDY to FWDING FMLMSG_BCAST_FMTODRVR_FIA_ONLINE Jan 1 00:02:17.264 FWDING to SELF TEST RDY FMLMSG_CMN_FMTODRVR_ADD_ARB If the last ASIC transition is noted as "SELF TEST RDY" -> CHIPINIT then a fiarsp process restart has likely been performed.
