Was running VSC 6.2P2 and had the same issue. Upgraded to 6.2.1 and the problem persists.
Failed on 'SNAPCENTER':
Activity 'Storage Discovery' failed with error: Error connecting to Host VSCSERVER. This host is not reachable
Activity 'Storage Discovery' failed with error: Error connecting to Host VSCSERVER. This host is not reachable
Activity 'Send EMS Messages' failed with error: Unable to find storage system for given resources. EMS message instead sent to the storage connection accessible by this user:svmfqdn
I was getting past this point when running SC 1.1.
