I'm trying to get vMotion up and running. Here is my config:
Two ESX hosts. 6 pNICs each. One reserved for vMotion, each.
VLAN 48 - iSCSI Network - 172.16.48.0, 255.255.255.240
VLAN 200 - vMotion - 172.16.200.0, 255.255.255.248
When I click on the Host and click Configuration tab, I click Networking and then "Add Networking."
When I select VMkernel (for vMotion) the Network Access page comes up. I assign a new vswitch and NIC. I'm now at the Connection Settings and here is where I run into the issue (i think.)
I name the Network Label (I'm matching this name on both hosts) ... I tag the "Use this port group for vMotion" checkbox. I assign the IP and SM and the "VMkernel Default Gateway" is already assigned but grayed out. The DG is the gateway for VLAN 48 .... not VLAN 200.
If I leave the Gateway as 172.16.48.1, I cannot ping the vMotion NIC/IP once I complete the wizard...but if I click the edit box and change the VMkernel Def Gateway to 172.16.200.1, I believe I will lose connectivity to the Service Console/Host machine. (On my last config, when I changed this setting to 200.1, my config got hosed and I had to re-format and re-install. I'd prefer not to do this :D )
In all documentation/best practice reading that I've done, it states that the vMotion network should be on a separate network/VLAN from the VM Network or iSCSI network. How can this be achieved if I can only assign one VMkernel default gateway?? (I have another VMkernel port created and assigned for the iSCSI network...)
What am I doing wrong? I can provide more information as necessary. Please help!
