NetApp vFiler DR with Data ONTAP Simulator Part 5: DNS Configuration
This article is part of a series.
Note: In case you already configured DNS settings while setting up the VMs (part 2 and 3) you can directly test name resolution with ping.
For the next steps it is advisable that both NetApp VMs are configured correctly. They should at least be able to resolve each other. If you plan to create a synchronous vFiler DR name resolution must work. If not you might get errors like “SnapMirror is unable to setup a multipath connection to vol_vfiler, resorting to the standard single TCP connection.” und “SnapMirror: destination transfer from 192.168.2.66_vfiler_con:vol_vfiler1 to vol_vfiler1 : Error in snapmirror sync mode negotiation.”.
You can choose between 2 DNS configurations: “Configuration with a DNS server” and “Configuration via /etc/hosts”. Make sure to always configure one of these options on both simulators.
