dedicated NICs for replication

[pfeifferl]

Hello,

how can I define specific NICs for the replication traffic?

We have 2 DSS v6 with each 6 NICs and we want to have 2 NICs dedicated to replication (bond?).

Hello,

Create your bond interfaces first. In my setup, I have Bond0 for iSCSI traffic, Bond1 for replication, and Bond2 for management. When you set up your bond interface, use ip addresses on the same subnet for both devices, so DSS-A Bond1 is 192.168.1.1 and DSS-B Bond1 is 192.168.1.2.

Next, under Configuration - Volume Manager - Volume replication, you set up the replication tasks, and that's where you specify the Mirror Server ip address, which is the address of the other DSS unit, so your DSS-A replication tasks will point to 192.168.1.2 and your DSS-B replication tasks (i.e., the reverse replication tasks) will point to 192.168.1.1.

One issue that I ran into was that I had created replication tasks with spaces in the name (i.e., "Volume 0001 replication" and while the task was created and ran, it did not show up in the iSCSI failover configuration. My advice is to create tasks without spaces.

Hope this helps,
James
