[ovirt-users] Issue in importing ISO storage domain in Ovirt 4.3

Hello, I'm managing Ovirt environment 4.3 and I'm very new to this area. The setup was already done by former colleague and right now I'm managing this environment. Recently, one VM's OS got corrupted and I have to re-install the OS in that VM to bring the VM up and running. For doing this, I need to import the ISO domain from gluster storage (this ISO domain is not present in ovirt engine now). While importing the ISO domain, I face the following error; "Error while executing the action: Cannot add memory connection. Memory connection 63566129-bb20-4b11-b5c2-5e943ab94bed already exists" I already searched this "63566129-bb20-4b11-b5c2-5e943ab94bed" image in ovirt server, target server and gluster storage server but I couldn't find it. Could you please help me in resolving this issue? I got stuck badly here. Thanks in advance! Best Regards, Hariharan
