I just loaded ESXi 4 on a server and i created 2 virtual machines and i went to add a second drive to one of the VM's and it gave me an error stating "There are insufficient licenses to complete this operation. Feature hotplug not licensed, requires have have"
Has anyone ever seen this error before?
That really sucks and is ridiculous and quite despicable IMO.
Now I have to revert back to ESXi 3.5, because this feature is absolutely critical, and the lack of it is a deal breaker.
I'll be strongly considering the competition which hasn't had any problems hot-adding virtual disks.
The cost of the advanced edition for such a basic feature simply isn't worth it.
That's only really useful if it's a brand new host. If the host was installed more than 60 days ago, the eval option isn't available anymore, because it expires. It might be useful only if it hasn't expired yet (which is a limited time period)...
Otherwise, switching back and forth between ESX Foundation license and Eval mode is not a good workaround for an environment that runs production VMs.
And the whole point of needing to hot-add a VMDK, is the VM is important, and you want to add more disk capacity without downtime.
The need arising for more capacity isn't something that normally occurs within 60 days of server deployment.
I sent an e-mail to VMWare requesting they lift this license requirement in next update. We are seriously thinking of moving back to 3.5i or moving to Xen (or KVM)...
Here is the reply from VMWare. Good news!
"This is a known bug, expected to be resolved by vSphere 4.0 U1. The correct behavior is that hot add of disk should work with every license.i.e. hot add of disk is still free.
Sorry for the confusion.
Thanks and regards
