We currently have Dell PowerVault MD3220i in our office. It's setup with two Dell PowerEdge R620 servers in a fail-over cluster configuration.
We purchased the PowerVault with only half of the disk slots occupied. I recently purchased 12 more drives in order to expand the volume capacity.
I've been told that this is a seamless process which should not incur any downtime. I have looked at the owner's manual but don't find the instructions to be clear.
Does anyone have a set of clear step-by-step instructions on how to add additional hard drives and expand the volume on the PowerVault MD3220i using the Dell Management software without any downtime?
