v10.2.3 units go active on boot
Just wondering if anybody else noticed when rebooting their BigIP 10.2.3 units in an HA pair, one of the boxes always goes active after reboot before the system has a chance to replicate the connection table from the partner unit?
I thought it was isolated and just something bad on a pair of 1600's... But after upgrading a pair of 6400's (10.2.3HF1), I notice the same thing.
Sadly enabling debugging on sod 'fixes' it... At the expense you have to put up with a truckload of verbose logging.
Anyone else?

- lkchenNimbostratusYeah, I saw that when I upgraded our 6400's to 10.2.3 and later 10.2.3HF1.
- Beinhard_8950NimbostratusI have not seen this on the 11050 boxes.
How is your setup?
For network failover I use mgmt and unicast.
However, I will verify this in the lab in some days because I know that I had one unexpected failover in the past but that was when I struggled with some cmp problems as well.

- lkchenNimbostratusOnly serial failover. Though we have vlan failsafe configured for one external vlan and one internal vlan.
- Beinhard_8950Nimbostratusi have checked now in my production boxen, however I´m not using serial but to avoid this behavior (without serial ) it´s mandatory to have unicast for mgmt interface (and for redundancy on some more vlan) and then it´s OK.
- HamishCirrocumulusFWIW I only see this on 6400's and 1600's. Not 3400's. That's with network failover only. No serial. It's consistent, and the 1600 that does it has just been reinstalled with a disk format. Same issue.
- giltjrNimbostratusA little late, but I was under the impression that you could not HA between different versions of LTM. I thought I read that in the doc dealing with doing upgrades on a HA pair. That if you were going to upgrade the standby box, you had to disable/disconnect all network connections.
