[ovirt-users] Re: How to detach FC Storage Domain

[matthew.st...@fujitsu.com]

If you destroyed, no.

To migrate the storage, intact, you need to shutdown the VMs, place the storage 
domain into maintenance, then detach, and remove the storage domain.  And then 
do an attach on the new DC.

I've been doing this iSCSI to migrate VMs from an existing DC to a new DC to 
alleviate load on the first.  (I had to spin up a new DC.  I was going to 
exceed the limit of hosts on the original one.)

Another quetion, I had done this before with NFS storage domain types and can 
list vms, templates and disk in reattached storage domain but for this FC I do 
not see any.
Do I need to perform an additioal action?

Hi Miguel,
You can try to destroy the storage domain:
Storage > Storage domain > select the domain > 3 dots menu > destroy.

Then just add it again to the desired DC.
