I get a vmotion error "A general system error occurred: Migration fialed while copying data. Timeout." only between hosts that use a port-channel for their vMotion traffic. I can vMotion between a host that has a port-channel to another that is not connected via a port-channel. I am using Dell 6448 switches. I am using the following hash algorithim on the switch "Source IP and Source TCP/UDP Port" the options are:
(Source MAC, VLAN, EtherType, SourceModule and Port Id)
(Destination MAC, VLAN, EtherType, SourceModule and Port Id)
(Source IP and Source TCP/UDP Port)
(Destination IP and Destination TCP/UDP Port)
(Source/Destination MAC, VLAN, EtherType, SourceModule and Port Id)
(Source/Destination IP and source/destination TCP/UDP Port)
I have two ESX 4.1 hosts with the following configuration:
ESX1:
Switch0 - vmknic0(1/g1),vmknic2(2/g1) Load Balancing: IP Hash
Port Group's
VMotion Network (VLAN 104)
Management Network (VLAN 103)
ESX2:
Switch0 - vmknic0(1/g4),vmknic2(2/g4) Load Balancing: IP Hash
Port Group's
VMotion Network (VLAN 104)
Management Network (VLAN 103)
Switch configuration:
interface port-channel 11
switchport mode trunk
switchport trunk allowed vlan add 101-108
switchport trunk allowed vlan remove 1
exit
interface ethernet 1/g1
channel-group 8 mode on
mtu 9216
exit
interface ethernet 2/g1
channel-group 8 mode on
mtu 9216
exit
interface ethernet 1/g4
channel-group 11 mode on
mtu 9216
exit
interface ethernet 2/g4
channel-group 11 mode on
mtu 9216
exit
I believe this is due to an incorrect hash algorithm type but I don't want to test each one to find out, anyone else use these dell switches in the same way?
