Hi guys,<br>
<br>
I've searched around a little but don't see much on how to do this.<br>
<br>
I'm running ovirt-engine-3.5.6.2-1.el6.noarch on Centos 6.x<br>
<br>
I have 4 x Centos 6.x hosts connected to an FC SAN with two different<br>
RAID arrays configured on it, one new RAID and one old RAID.<br>
The new RAID is shared as a new FC storage domain, the old RAID as my<br>
old Master storage domain.<br>
<br>
I have moved all VM's using LSM to the new storage domain and I would<br>
like to remove my old storage domain now, so that the old physical hard<br>
disks can be removed out of my SAN.<br>
<br>
If I go to "Disks" on the old storage domain I only see two named<br>
OVF_store etc, so it looks like it's ready to be decommissioned.<br>
<br>
How can I promote my new domain to the master and remove/destroy my old<br>
master domain and can it all be done without any VM downtime?<br>
</blockquote>

Hi Neil,<br>
<br>
- When you're sure no VM disk remains on the old SD :<br>
- Select the old storage domain<br>
- in the 'Data center' tab at the bottom of the GUI, use the 'Maintenance' button<br>
- the Master role will automagically switch to the remaining storage domain (it can take some seconds)<br>
- once there, you're free to detach then destroy the old storage domain.<br>
