Hi All

I now update to the latest Open-e V7 Version (7.0up07.9102.7356 64bit).

Now it is possible to add/remove scsi targets, resize volumes... as mentioned in the webinar.

Thank you all for your comments.
Working functions:

Add new volumes into a running cluster
Remove a volume from a running cluster
Move volumes between resource pools for load balancing tuning
Expand the volume size while the cluster is running
Power outage simulation of both cluster nodes and starting the cluster after a power restore
Software update while running a cluster
