How to Troubleshoot High Availability(HA) on ION Devices in Prisma SDWAN?

1. Validate the HA configuration on UI and Elements
2. FIx the HA issue if there is a configuration issue

• Prisma SD-WAN
• Prisma SASE
• ION

1. Double-check all HA configurations on the active and backup devices on the UI.

2. The ION device will synchronize with the configuration on the UI.

xxxxx-HQ-NEW# dump spoke-ha config
Name                    : xxxxx
Enable                  : true
Cluster ID              : 1674592256246012745
Description             :
Advertisement Interval  : 5
Preempt                 : true
Interface               : controller 1
Group ID                : 133
Base Priority           : 180
Track Interface         : 13    reduce 50

3. The ION with the highest priority takes the following active role:

DEU04569-HQ-NEW# dump spoke-ha status
Active                  : true
Peer Connected          : true
Base Priority           : 180
Effective Priority      : 180
Updated                 : 2023-01-28 06:50:56.871 (112h52m59s ago)
DEU04569-HQ-NEW#

4. If the "Peer Connected" cannot be recognized, use the ping command to ensure that the interface used to exchange the HA heartbeat information is reachable.

xxxx-HQ-NEW# ping controller1 10.40.143.85
PING 10.40.143.85 (10.40.143.85) from 10.40.143.84: 56 data bytes
64 bytes from 10.40.143.85: seq=0 ttl=64 time=0.318 ms
64 bytes from 10.40.143.85: seq=1 ttl=64 time=0.363 ms

5. ION logs HA information on ham logs; review logs to obtain a better understanding of the HA issue.

xxxx-HQ-NEW# file tailf log ham
