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.
What release are you on? In 8.1.4 there's a bug involving the HA1-B does not come up as expected. Fixed in 8.1.4-h2 and later.
From the release note on 8.1.4-h2:
Fixed an issue on a PA-3200 Series firewall running PAN-OS 8.1.4 in an HA configuration where the HA1-B (backup) port did not come up as expected.
FYI - Here is a workaround for someone who wants to bring up the HA1 Backup before fixing it by upgrading the PAN-OS (if it's a bug - last time it was).
Step 1. Change the Port type from ha1-b to management on Active firewall and Commit (Device -> High Availability -> General > Control link (HA1 Backup)
Step 2. Revert back to the previous configuration with the Port type: ha1-b, along with the IP address and Commit.
This workaround should bring up the HA1 Backup.
Hope this helps!

Thanks for advice, i've noticed it before. It looks like PA is very devoted to management interface, even if there is no port chosen, management is used 🙂
Also this behaviour is observed after migration from older PA. As far as i see there is couple places where imported config has some artefacts comparing to manually made changes.
