[ovirt-users] Bring down one of multiple storage domains in a data center

Hi, We are planning to use oVirt to manage our virtual machine infrastructure. We would like to connect two different storage boxes to the hosts, which I believe will result in two storage domains in the same datacenter for oVirt? One of the storage boxes sometimes has to be powered down during building maintenance (electricity, cooling, ...). Will the data center with the two storage domains attached still be considered "up" when one of the storage domains is no longer available? Is it sufficient to power down the VM's with disks on the affected storage domain and to put the affected storage domain in maintenance? Will oVirt keep the datacenter "up" and keep on managing the remaining VM's on the other storage domain? One of the storage domains will be a SAS-connected external storage box. There will be two SAS connections per host to the storage box so multipath should see the two paths. My understanding is that anything detected by multipathd is considered "FC" storage by oVirt. Is that correct? Regards, Rik
