[SOLVED] Both HA firewalls down after upgrade to 21.7.8

[martin.kouba]

I have two HA firewalls fw01 and fw02

I have upgraded the fallback firewall fw02 first to make sure we still have VPN and everything working while upgrading.
Upgrade finished without any errors and went in to REBOOT.

But it never came back from reboot and worse for some strange reason now I can't access fw01 as well.

Maybe fw2 needs another power cycle?

Can only check tomorrow. Nobody on site right now and I am 300km away.

I am puzzled why fw01 went down as well.

Sounds like a misconfig which was already there. I also cant see a reason

Quite strange, but what actually happened is that the connected switches went into a fault state.

Here we have 2 HP 1810G-24 switches sw01 and sw02.
fw01 and fw02 are both connected to sw02 with link aggregation to take care for HA.
sw01 is taking care of user LAN.
Both switches had their FAULT light on. Even after a reset the light stayed on. After disconnecting sw01 from sw02 and another restart sw02 came back on.
sw01 is heavily flashing all lights after a factory reset. No idea how that got triggered by the firmware update of the firewall, but that is what happened.
