Thank you both for the answers.
It seems that there is a sync issue between vCloud and the database as some inventory tables are populated while others are not. So I've cleaned the inv tables and restarted vCloud services and reconnected to vCenter but it did not help. The issue remained the same.
@Sreec: I use VMware-vShield-Manager-5.5.0-1317534 OVF and SQL 2008 R2 Express
VC and VCD databases were created manually by clicking on new DB and everything is on default.
@IamTHEvilONE: HA, DRS and SDRS are all enabled. When creating a Provider vDC, storage policies are not listed, only the "Any" tag is there, including all the datastores which have tags.
After creating a Provider, hosts and resource pools are listed, now I only miss storage policies. So it seems that resource data is gathered after the firs Provider vDC is created. I expected all resources listed which are available on a vCenter.
I'll recreate storage policies now.
