Vmotion ping losses

nikkar — Thu, 31 Jan 2008 08:22:00 GMT

We got a lot of ping losses when we do vmotion in our cisco and hp switch enviroment (15 to 40 ping losses) . We changed the "notify switches to yes" in the switch on every esx server.

After that we lose only one ping when we do vmotion.

Troubleshooting Vmotion

1) is your vMotion network a private physical switch/VLAN only used by ESX servers, or is this on a public network.
2) Are you routing the vMotion between two networks.
3) Please post output of:

esxcfg-vmknics -l
esxcfg-route -l
esxcfg-nics -l
vmkping vMotionIPofTargetHost

4) review /var/log/vmkernel for any errors regarding the vMotion.
