Hello, I've make a lot of cross test to enable high avaibility on ESXi VMs. SN different and virtual mac address are defined in boot parameters. On each tests, it's crash after 10~20min of configuration and failed back to original state. We can note that on both DSM, the error message is that HA was configured as slave and not one with master en one with slave. maybe a point for search. any other idea? Thank's!
