Thanks very much for your help Don...
Hi guys.. we have 7 PS6010 storage units all running firmware level 5.07. We need to upgrade to the latest firmware level 5.2.2. Our storage forms part of a Hyper-V failover cluster solution and our operation runs 24 hours a day. Can we do a 'live' firmware upgrade without any repurcussions or should we stop all VM's and shut-down the entire virtual environment prior to performing this upgrade? Approx how long would the firmware upgrade for both scenarios??   Thank for the help guys...
