[ovirt-users] Second DataCenter isn't available to attach Export Storage Domain

I have put the export domain into maintenance, detach from Datacenter 1, and when I try to attach it to Datacenter 2, attached to the same engine, when the Attach to Data Center dialog pops up, it only shows Datacenter 1. What am I missing here? Please be kind, I’m very new to oVirt… Version 3.6 CONFIDENTIALITY NOTICE: This email, including any attachments, is for the sole use of the intended recipient(s) and may contain confidential and privileged information.
