Our situation (vmotion network):
ESX1 = 10.0.0.1,
ESX2 = 10.0.0.2,
ESX3 = 10.0.0.3,
ESX4 = 10.0.0.4,
ESX5 = 10.0.0.5,
All vmkpings and vmotions OK except between ESX4 and ESX5 with other hosts.
At 10% of vmotion process appears: "Migration to host <10.0.0.3> failed with error (Timeout (0xbad0020))"
]# vmkping 10.0.0.4
PING 10.0.0.4 (10.0.0.4): 56 data bytes
--- 10.0.0.4 ping statistics ---
3 packets transmitted, 0 packets received, 100% packet loss
Some ideas ?
