Go to SolutionDataDomain - ifgroup setup - replication
Howdy all,
I have following setup - DataDomain 6800 with 8 data interfaces:
# net show hardware

File replication is allowed on ifgroup.

As I understand this, only the 4 ips configure in "default" ifgroup should be used for Mtree replication, however after checking iostat I can see eth4d with ip 10.98.226.105 sending a lot of data. After checking with Network team it seems that this is the port that is sending Mtree replication data to the remote DataDomain.
Is there something I'm missing?
Additionally I'm thinking of extending this default ifgroup of the remaining 4 ips for (eth4x ports). Will that cause any network disruption? Will I need to do any extra config for clients to use those new ports (either for replication or clients connections)?
Cheers!
