HA Configuration on PA-3220 - HA1 is UP but HA1 Backup is Down

L1 Bithead


I have both PA-3220 HA1-A and HA1-B links connected back to back to each other with a previously verified cable but only HA1 is coming up greeen while HA1 Backup is showing down. The HA1-B interface LEDs on both PA-3220 show green.


Any feedback or suggestion is greatly appreciated.

Same problem with upgrade to 9.1.7

Resolved by changing  the ha1-b interface to management and than back again.

Reboot didn't help.



I configured pair of PA 3220 in HA and running PAN OS 9.1.5 no issues with HA1 and HA1 backup so far.




problem still persists on 9.1.8

reconfigured and it started to work again

didn't try the reboot, this is faster 🙂

While upgrading PA 3260 from 8.1.15 to 9.1.5 I saw this  issue first time.

Fix was to change HA1-b interface to Management and then back to HA1-b

For anyone ending up here first like I did - you need to set the gateway in the HA1 config.  without it, the interface gets marked down.  I just set the gateway to the IP of the HA1 interface of the other side on both sides and it cleared this issue.
