To add some more information we are currently using UniSphere instead of NaviSphere with EMC Provider 184.108.40.206
Seems like the username/password being used to talk to the clarion aren’t valid but that is just a guess. Try to log into the Unisphere gui using the username/password they are using to discover the clarions via the provider and see if that works. The username/passwords must be admin level and global scope.
If that fails to resolve the issue, you could try reinstalling with the latest provider (v4.4).
This is a slightly late thread revivial reply as I've recently had the same issue. The probelm is the account on the Array that is used for 'reporting' doesn't have high enough privledges (Hence the access denied). If you are using the Operator 'Storage Domain Role' - This is too low, you need to elevate the account (we currently have set to administrator at the moment) although you should look at the other account types to see what best suits your needs & this should resolve this problem.
