Recover MSA2000fc

[judaster]

Hello and thanks for reading,

We've had a problem with our MSA2000, I deleted all volumes and Vdisks to start from scratch.

The problem nos is that when I try to create a new vdisk from the management console I receive the following error (it doesn't matter the selected settings):

Request failed because configuration has changed - Please wait 10 seconds and retry request (Config Change Error). "3"

I also tried creating vdisk from CLI. I receive the "Command completed successfully" but when I issue the command "show vdisks" it appears empty. 

Any hint would be highly appreciated.
