then you dont have a valid NOW account. Please follow this document to troubleshoot:

Likely you never registered a NetApp serial number to NOW account
You wont have access to github until you sign up at www.snapcreator.com.
As for DFM/PM or integration with OC products, SC integrates with many:
1) DFM proxy - allows SC to communicate through DFM so no storge controller access
2) OM Events - SC can send events to OM
3) SnapDrive - SC fully integrates with SDW and SDU
4) PM - SC fully integrates with PM allowing for it to register snapshots in PM and use PM to perform data protection
5) Integration with SME and SMSQL
6) OSSV integration
And that is just off top of my head
There are no plans to use PM schedules when we are using OSSV through SC, that would be rather difficult to do, you can certainly open an RFE for it but it likely wont get worked on in the short-term at least.
