Troubleshooting Alarms
Step 2 Slot Centric De-bugging
a. Use dspdevalms XBARCORE -pslot <pslot> to display the core alarm for the specific slot.
b. Use dspdeverr XBARCORE -pslot <plsot> and dspdeverrhi st XBARCORE -pslot <pslot>
to display the current and cumulative error counters for the different error types. The different error
types that were in alarm in a. will have corresponding error counters.
Step 3 Plane centric de-bugging
a. Identify the particular crossbar plane that is reporting alarms against all service modules using
dspxbarplanealms.
b. For the above switch card and plane, use dspdevalm XBARCORE -xslot <xbar_slot> -pl
<plane_no> to display the alarms reported for different error types.
c. Use dspdeverr XBARCORE -xslot <xbar_slot> -pl <plane_no> and dspdeverrhist
XBARCORE -xslot <xbar_slot> -pl <plane_no> to display the current and cumulative error
counters for the different error types.
Crossbar Port Alarms
If crossbar port alarms are present, complete the following steps:
Step 1 Use dspswalms to verify if all SM slots are reporting crossbar port alarms or only if specific slots are
reporting port alarms. If all slots are reporting port alarms proceed to Step 2, else proceed to Step 3.
Step 2 If all slots are reporting crossbar port alarms, use dsplog -mod HMM_ and dsplog -mod SHM_ to
identify the switching plane against which all the slots are reporting errors. The particular switching
plane may be faulty.
Step 3 If a specific slot is reporting errors then cc to the slot and check if the humvee’s on the slot are reporting
any errors. Use shellconn command hvTestGetErrorCounters 1 (reads the accumulated error counter
values) and hvTestGetErrorCounters 0 (reads the current error counters).
Crossbar Bandwidth Alarms
If crossbar bandwidth alarms are present, complete the following steps:
Step 1 Use dspxbarslotbwalms to identify the slots reporting bandwidth alarms.
Step 2 Use dspxbarslotbwalms <pslot> to get detailed information for the slots reporting bandwidth
alarms in Step 1.
Step 3 Use dspxbar <plane_no> to verify that the planes whose availability is reported UP but operational
state is reported DOWN have been shut down. Use dsplog -mod HMM_ and dsplog -mod SHM_ to
identify the reason for shut down.
