When i try to import using slapadd -f hdb.ldif, some of the entries in sysadmin role are not getting import, not sure what should be the reason. Actually hdb backend to hdb backend import also same behaviour if i pre-create with above root schema and keep the other server in cluster is running. If i dont pre-create schema or if i dont keep the other server running in a cluster i dont see this issue.
slapadd by default outputs an error and will not continue (unless -c is specified) when it has a problem adding an entry. You should provide the error encountered.
I'd also note that you appear to be adding LDIF that is missing operational attributes. That will not work well if you're running in MMR and expect replication to work.
