One of the 8400 Arrays Storages disappears suddenly from the Command View Array lists

Hi

I have 3*EVA 8400 with XCS 10001000 and 2*EVA 4100 with XCS 6050, also 2 command views installed in my environment. my Command View version is 10.1, when I want to manage one of the EVA 8400s with one of the command Views,  it will become available on navigation pane after taking a long time (about 2 hours), and suddenly becomes unavailable after 1 or 2 days, (I should mention that it will be detected as unmanaged array on my second CV, and it can manage it after several hours, but the same problem (disappear) happens agian after 1 or 2 days.)

 

I've checked all the physical connectivities, and everything seems fine. I wonder if anyone has any solution for this problem?
