I created a new Data Domain (detached from all the DCs) and clicked on 'Re-Initialize Data Center'.
Now I'm able to select this Data Domain as the new Master. However when I select it and click OK I get the following error:
Error while executing action: Cannot recover Data Center Storage. The relevant Storage Domain's status is Active. =20 as i said earlier=2C re-init DC is for emergency flow when your DC is dow= n.

re-init DC is for emergency after you lost all your SD's and allows = you to choose a data domain not yet attached to any DC. just deactivate the domains you won't won't to be master domains and engine will elect another domain as master.

So that means you have configured your other storage domains und=
er another DC=2C but you haven't configured them on the relevant DC= =2C cause 'There are no compatible Storage Domains to attach to this Data Ce= nter'
Or they are Detached from DC.

When I click on 'Re-Initialize Data Center' I get the following message: There are no compatible Storage Domains to attach to this Data Center. Please add new Storage from the Storage tab.

Hi Sokratis=2C
You can go to Data Center main tab=2C choose relevant DC=2C cl= ick right click on the DC=2C choose 'Re-Initialize Data Center'=2C in this w= indow you can choose another compatible Storage Domain and choose him to be = your master Data Storage Domain.

Hello=2C
I would like to remove the Master Data Domain because I need t= o decommission the underlying storage device.
Is there a way to manually change the Master Data Domain? Will=

I then tried to activate the Master Data Domain without success. Finally I tried to "Re-Initialize Data Center" but there was no Data Domai= n available to become Master so now I can't find a way to Activate the Data= Center. Fortunately none of the VMs was affected. What can I do now to re-activate the Data Center?
