Enabling ARP Redirect For Compellent Arrays
In order for controller failover to work correctly when using ESX and Compellent arrays, you must enable arp redirect on your ESX hosts. If, for instance, you have a vmhba numbered vhmba33, you can check to see if arp redirect is enabled by connecting to the console and typing:
esxcfg-hwiscsi -l vmhba33
If arp redirect is not enabled, you can simply enable it with the following command:
esxcfg-hwiscsi -a allow vmhba33
