vmkping at the console. (remotely via ssh).

and you can then specify which VMKernel Portgroup to send the packets through.

so how do you do this ?

you ssh into one of the hosts and they you SHOULD be able to vmkping all of the vmkenal ports gorups on the other host ?

i think that is it right?

thanks !!!!!!!!
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Yes, exactly that.

use the IP Addresses associated with the VMkernel portgroups.

is there anyway to do like a tracert , I suspect that I am getting a ping reply but there may be an Ip conflict , can I get the mac addy with a vmk command ?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
do you get a vmkping reponse ?

how have you defined your vmotion network ? it should be on it's own network and IP Address range ?

no tracert or MAC Address. But all VMKernel Portgroups are unique MAC Addresses ?

please upload screenshots of your networking
NAMEWITHELD12Author Commented:
yeah I get a responce from vmkping for all of then , however I suspect that it is not what I think it is and that some other device is responding to the vmkping

I will check the MAC addys to make sure they are unique
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
that's one host!

cannot tell if the the other host is on the right network, or setup correctly.

what IP Address are you using for Management and vMotion ?
NAMEWITHELD12Author Commented:
hi , I have the second server in the cluster esx2 configs over at my other post


interesting if I run the vmotion network over the managment vmk it works fine , I unchecked the box for vmotion on the vmotion network and had it run over the same vmk that the managment networks runs on

so next I will remove and recreate the vmk port for vmotion and assign the same ip addresses that exist now , i will retry vmotion

if that does not work i will find a new range of ip ( not used for anything else) like for example and leaving the gateways as is

and then test vmotion

sound like a good plan????/

Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Yes, good plan.

I would always recommend a seperate network address range for vMotion. This is best practice, that vMotion traffic is isolated from other traffic.

the eventual problem was found  in that one for network interfaces ( iSCSI ) was set to carry the vmotion traffic as well . this was found in the HOSTd log I think !!
