Veritas Storage Foundation for Windows 4.3 MP1 / Windows 2003 Server SP2
Replication status for one RLINK is showing as "Activating" with a orange Arrow pointing upwards.
DCM Log Usage is at 15% with nearly 13 million blocks pending.
The icon for the RVG:secondary has a pause symbol next to it.
How do I resume synchronization between this primary and secondary?
Via the GUI, I have tried stopping and starting replication, using TCP and UDP as the replication protocol and tried hostnames and ip addresses as the Secondary side IP.
I have tried dissocating the SRL log connected to the secondary and then associating it back but to no avail. The replication status just sits in "Activating".
I have rebooted the primary and the secondary many times but that has made no difference.
I have tried vradmin -g <DG> resync <RVG> but that just returns a prompt.
vxrlink -g <DG> -i 5 status <rlk> shows that RLINK is in autosync with 15% remaining.
Other primaries that replicate to this secondary are all replicating without issues.
I guess my questions are:
Why is this specific replication stuck in Activating / Paused?
How do I get it out of this stuck state?
Happy to provide more details / screenshots if helpful

Have you tried restarting the cluster nodes? Sometimes the VVR RLINK goes in a frenzy state and a server reboot will do the trick.

Thanks Virgil but this is a simple primary / secondary setup and not clustered
The following has been tried but to no avail:
Have tried rebooting both the primary and the secondary servers
Have tried stopping and restarting replication as well as pausing and resuming
Have tried deleting the secondary and recreating it
Have tried vradmin -g <Diskgroup> resync <Rvg> on the primary
Have tried dissociating and re-associating the SRL
All result in the same - status Activating, blocks pending and no movement.

The Replication Monitor, in Veritas Enterprise Administrator (VEA), maintains a status of "activating" for replication. No blocks are being sent to the secondary site.
When replication is stuck in the "activating" state, it usually indicates that there is a network communication problem between the primay and secondary sites.
1. Use vxprint to determine that the Rlinks, hostnames and IP addresses for the primary and secondary replication partners match each other. Information on this can be found here: www.symantec.com/docs/TECH52571
2. Use pathping to test network connectivity between the primary and secondary sites. Pathping is a Microsoft utility that comes with Windows. More information on this utility is found here: technet.microsoft.com/en-us/library/ff963096(WS.10).aspx
Note: Test connectivity in both directions. Confirm that packets are being sent back and forth using the same route. If packets from the secondary take a different route to get to the primary, differences in timing problems may occur, causing the primary not to receive acknowledgements from the secondary in a timely manner.
3. Try to pause and then resume replication.
To pause replication:
4. Use vxrlink to detach and reattach the primary rlink from the primary site using the following syntax:
To detach the rlink:
vxrlink -g [disk group] -r [rvg] det [rlink]
To attach the rlink:
vxrlink -a -g [disk group] -r [rvg] att [rlink]
Note: The information required for these commands can be found using vxprint.

Have tried your suggestions but no change unfortunately - VVR still sits in Activating with a "Pause" symbol on the RVG:Secondary Host.
The RVG:Primary host has a symbol that looks like a page with three written lines on it (rather than a "play button" symbol) if that helps at all.

It seems that all the servers / connections suffering this problem have the following flags:
flags : primary enabled attached read write autosync resync_paused
for both the local RVG and the Rlink.
Looking at the manual for VVR all it says is thar "resync_paused" indicates there is a problem but does not suggest where to look or what the problem might be.
Stopping and Starting replication from either the primary or secondary does not help
Pausing or resuming replication from either the primary or secondary does not help
Deleting and recreating the RDS does not help
Rebooting the primary and secondary does not help.
Other primaries are replicating with this secondary so it is unlikely the issue is with the secondary server.
Currently the primary is in DCM logging so tried vxrds -g <DG> resync <RVG> on the primary but it just returns a empty command prompt.
Network name resolution, ping connectivity, VVR heartbeat, data and sync ports all match and are working.
Any ideas why the Resync_Paused flag is set and how can I investigate why / remove this flag?
