Hello Infinity_sup, Based on the information that you have provided I would say that your issue is java related.  If you look on your system and see when your java was last updated I am sure that it was just recently.
Good day, In the last few days I found I can't log into my two VNXs I get the unisphere windows but its white without the text boxes for user and password, and even if I try to insert them blindly it doesn't work I tried it vie IE and via VNX launcher, on several computers including Windows 7 computer Unisphere Service manager Launcher works fine How will I be able to manage my VNXs with this problem? (Or the time has come to throw away two working VNXs)
