I had similar issues... your ESX admins need to make sure round robin is set on every datastore on every ESX host. If you have 10 ESX hosts, and 10 data stores, they will have to clickity click 100 times or learn to script it. There are commands inside the implementation guide to make this the default for all NEW datastores added after the default is changed.
http://kb.vmware.com/selfservice/micros ... Id=1017760I suspect what is happening is that you have 1 or more ESX hosts still using the default "Most Recently Used" policy.
You shouldn't have to click, you should just need to change the policy and reboot the host, the PSAP policy change should take effect the next time the storage stack goes through its claim rules unless you've manually changed something (ie if you manually assign a policy it will keep the manual change but if it was set by existing policy automagically it should change the next time things are evaluated, this is my experience with 4.0, 4.1, and 5.0). Also like almost everything else in VMWare it can also be scripted.
