I'm trying to configure OnCommand Balance for the first time. I am running 22.214.171.124 of Balance. I connected up just fine with storage but am not able to get connected to my vCenter Server. I am using our AD crediantials but it won't connect. It says the username/password is incorrect. I am able to use the same creditials and log in to vSphere just fine.
Make sure that the credential you are using is at the datacenter level in Virtual center (Top of the navigation Tree in Vsphere) other wise it will only be able to monitor the cluster or host it has access to. Try logging into the vcenter/vsphere with the credentials you wish to use in Balance . Then rule out a typo by re- entering the creds into Balance. The credential only needs to be a read-only but if you have another credential to try, sometimes it sheds some light on why its failing. Lastly, make sure it is a supported Vsphere version e.g 4.1, 5.0 etc
Everything you stated appears correct and the "& " should be ok. You may need to open a support case for them to look more indepth at the server logs. See KB articles on How to get the Balance diagnostic logs.
