Hi Vincent,
Can you give some more details on you setup: 1. Have you configured with ESX/VC? 2. Which version of VMware server are you using.
Can you try powering off the instance and then perform a volume attach.
P.S: You could try searching for "The attempted operation cannot be performed in the current state (Powered on)" in http://kb.vmware.com/ if it helps.
