Subject: RE: [ovirt-users] Reinstalling a new oVirt Manager
Do you think that I can import the SDs in my new Data Center without any risk
to destroy the VMs inside them ??
Thank you for your advice.
If no other engine is managing them, you can safely import the existing storage domain.
As usual, is always a good idea to keep a backup.

Objet : Re: [ovirt-users] Reinstalling a new oVirt Manager
Ok great, I can see the different storage that I want to import, but I can't
see the VMs on the un-connected pool.
So anyway I have to go further and import the storage domain passing the
alert message.
Am I right ?
No other way to see the VMs in SD :

You can execute this on one of your hosts.
# vdsClient -s 0 getStorageDomainsList
to get storage domain list, than
# vdsClient -s 0 getStorageDomainInfo <domain UUID> for each of them till you
identify the domain you are looking for.
You can also find there the pool UUID.
Than
# vdsClient -s 0 getVmsList <pool UUID> <domain UUID> To get the list of VMs
on that storage.
