If neither can be done then that failover concept won't work. Alternatively, the obsolete entry can be deleted (so it gets reARPed).

You need to make sure that a gratuitous ARP (GARP) is sent by the failover server and that this GARP is properly processed by all relevant nodes in the segment - they all need to update their ARP cache tables.
The "IP hash-based routing" is about L2 load balancing - which egress port is used - and has no relevance for IP routing. The ESXi's vSwitch doesn't care about IP addresses, just MACs. Moreover, I did not check this with application level but only with ICMP but I would like to confirm that exsi IP hash-based routing and lag not playing wrong here by effecting the failover.

The failover software feature is working perfectly fine but when virtual ip (192.168.60.12) assigned to db_slave I cannot ping it anymore from the gateway. when I switched off db_master VIP will be assigned to db_slave. For normal scenario VIP 192.168.60.12 assigned to db_master. I can ping other nodes outside my setup and LAG working fine when I remove one cable. I configured virtual port group and assign vlan 60. LAG configured as a trunk port and I terminate VLANs inside the exsi port groupsĪll of my database servers are on vlan 60 and those are the only VM on the exsi at the moment NIC teaming configured with IP hash-based routing with the of LAG configured on the switch side ( NO LACP). db_master = 192.168.60.10Įach exsi node have two interfaces.
We have two exsi nodes and two virtual machines on those exsi nodes as master and slave. if One node fail reserved VIP will be assigned to another node We are deploying HA database cluster on exsi which based on virtual IP concept for failover.
