DataDomain - ifgroup setup - replication
Howdy all,
I have following setup - DataDomain 6800 with 8 data interfaces:
# net show hardware
Port Speed Duplex Supp Speeds Hardware Address Physical Link Status State
----- ------- ------- -------------- ----------------- --------- ----------- -------
ethMa unknown unknown 10/100/1000 00:60:16:ab:09:ba Copper unknown down
eth1a unknown unknown 100/1000/10000 00:60:16:9b:5b:30 Copper unknown down
eth1b unknown unknown 100/1000/10000 00:60:16:9b:5b:31 Copper unknown down
eth1c unknown unknown 100/1000/10000 00:60:16:9b:5b:32 Copper unknown down
eth1d unknown unknown 100/1000/10000 00:60:16:9b:5b:33 Copper unknown down
eth3a 10Gb/s full 10000 00:60:16:99:26:84 DA Copper yes running
eth3b 10Gb/s full 10000 00:60:16:99:26:85 DA Copper yes running
eth3c 10Gb/s full 10000 00:60:16:99:26:86 DA Copper yes running
eth3d 10Gb/s full 10000 00:60:16:99:26:87 DA Copper yes running
eth4a 10Gb/s full 10000 00:60:16:99:26:60 DA Copper yes running
eth4b 10Gb/s full 10000 00:60:16:99:26:61 DA Copper yes running
eth4c 10Gb/s full 10000 00:60:16:99:26:62 DA Copper yes running
eth4d 10Gb/s full 10000 00:60:16:99:26:63 DA Copper yes running
----- ------- ------- -------------- ----------------- --------- ----------- -------
Interfaces eth3x are added to the default ifgroup with ips as shown:
---------- ------- --------- ------- -----------
default enabled 4 1 1
---------- ------- --------- ------- -----------
---------- ------- -------------
default enabled 10.98.226.100
default enabled 10.98.226.101
default enabled 10.98.226.98
default enabled 10.98.226.99
---------- ------- -------------
---------- ------- ----------------
default enabled *
---------- ------- ----------------
---------- ------- ----------------- -----------------------
default enabled * *
---------- ------- ----------------- -----------------------
File replication is allowed on ifgroup.
Client may use any interface.

Hello there!
One clarification: Ifgroups are for DDBOOST operations (backup or Managed File Replication)
Managed File Replication is Networker cloning or NetBackup SLP Jobs.
So, ifgroups are not even considered for Data Domain mtree replication.
For mtree replication you should add a virtual interface aggregating all the eth3* physical interfaces under the same veth name.
Or if you have more than one destination target, you can dedicate a different interface to communicate with each destination (adding static routes)
Hope it helps.
Regards
Gonzalo

Thanks for the explanation, that makes a lot of sense now. I had the virtual network interfaces configured for all of the physical ones.
kind regards

At some point in time, probably the ifgroups will support mtree replication, but not yet.
So your idea was not wrong, just not ready yet.
Kind Regards,
