Fail to Login to EMC VNX5300

Try if you can ssh (putty) into the control station and if you can open http:///setup

IF that works then most likely your system is fine and you have one of the problems with UniSphere login or certificates mentioned in your screenshot

Did you happen to create/change the login on one of the block/file side and not sync it up to the control station?

check if this solution works for you.

in additional, you could also try this.

Login to the SP through the management port using a laptop computer and disable the IP Filtering State.
--> Setup page
  --> "Set Administration Access Restriction"
    --> IP Filtering State: "Disable"

Is this a new install ?

Ensure you have accepted the security certificates and the CS-DM-SP

connectivity is proper. If not tried, try logging in from different

system/browser.

Dears,

I've try all what you talk about but nothing works even if you connect to the service port you can ping it but you cannot browse the unisphere from it, using putty it login successfully but I don't know my the user name and password knowing that no one change them if you know what is the default credential for SP service port.

Thanks,
