After import storage many of my vm's disks not appear

Hello all. It is been a while that I used the oVirt and on the same time, the company where I started to work, has a big problem with the engine, we lose it. We did not have any backup. To try recovery the enverioment I installed a knew oVirt, this time Hosted Engine, and import the Storage. I could import and start some vm's but the most part not appear for me, dosen't show on "Disk Import", "VM Import" and any place. I know that is there, because show me that size. May I see, like list, this disks? I can't do this throught oVirt web. Is there any way to bring dist disks back? I already search this tasks but with no luck. oVirt ver: 4.2.8.2-1.el7 Any one can help, please? Best regards. -- Atenciosamente, Kalil de A. Carvalho
