OLD POST REVIVED......
We seem to have an issue with one of our HA clusters.
The master and slave both connect to a stacked Cisco 3750x eg UTM Lan Port (master) > Cisco g1/0/1, UTM Lan Port (slave) > Cisco g2/0/1
All interfaces on UTM are like this.
What happens if I disable HA whilst both UTM's are online?
In reply to Louis-M:
If you disable HA in the Master, the Slave will do a Factory Reset and shutdown. When you power it back up, the Master will sync to it again and your Hot-Standby setup will once again be in place.

Now the thing that I have to ask is.... is it safe to leave all the interface cables in place?
I unplugged them all to be on the safe side (apart from the HA cable) but I wouldn't have if it's not required?
The safest when disabling HA is to not change anything else, Louis. After the Slave has done a Reset and shut itself down, then you can disconnect the cables. Just be certain that you hook them up correctly before you turn on the Slave node again.
yes that's how we did it. We had an issue with the sync and I wasn't sure what caused it. They just wouldn't talk to each other although they had previously.
Thing is, we did a x32 to x64 upgrade a while ago and I wasn't sure if that had caused the issue. I wasn't sure if a factory reset would revert it to the original x32 so i brought the other unit up sperately so I could access it via the shell and check if it was x64 (which it was)
So, a factory reset only appears to wipe out the config and not the firmware/db version.
This time around, I waited for the unit to sync and then attached the interfaces. In future, I will leave all cables alone.
