Avamar + DD Replication ports needed
Dear all,
I try to replicate one Avamar + DD to another Avamar + DD. I have to open firewalls beetween all systems
I have opened :
- Avamar 1 <> Avamar 2 : 27500, 28001, 29000, 30001 and 30003
- DD 1 <> DD 2 : 2051
- Avamar 1 > DD 1 : 7, 22, 111, 161, 2049 and 2052
- Avamar 2 > DD 2 : 7, 22, 111, 161, 2049 and 2052
- DD 1 > Avamar 1 : 163
- DD 2 > Avamar 2 : 163
Now I can backup and restore on each site (1 and 2), but when I try to replicate one site to each other I have an avtar error, I think Avamar 1 try to connect to DD 2 but I don't know on each port. I have the following error in avtar.log :
2018-06-18 08:07:11 avtar Info <10606>: Connecting to Data Domain Destination Server "DD_2" (LSU: avamar-1528369857, User: "********")

2018-06-18 08:26:39 avtar FATAL <40009>: DDR encountered errors.
When I do a netstat on Avamar 1 I saw a tentative on portmapper (111) to DD 2, is it normal?
I can't find anything in Dell Emc documentation, if someone have a good idea... I precise that Replicas at source is enable.

Ok, with my network engineer we find that Avamar 1 need to communicate with DD 2 on ports 111 UDP and 2149 !
Replication is now OK, but I think that many ports are unneeded in our platform (like 22 or 2152).... I'm sad that Dell EMC can't explain which are the minimal ports requirement.

assuming avamar1+dd1 is source and avamar2+dd2 is target then need 111,2049 and 2052 from avamar1+dd1 to dd2 inbound (in additon to the other avamar to avamar ports) btw, ddboost is based on NFS, so source Avamar1 connects to dd2 on 111 (portmapper), and nfs port 2049. the source DD1 connects on port 2052 on target DD2.
cheers,
