What’s the (SnapMirror) syntax, Kenneth?

I did what I thought was my due diligence: reading the relevant vendor documentation for SnapMirorr for each version of Data ONTAP, 7.3.2 and 8.0.3P3. What I failed to do was read a few lines further than I actually did – I missed a simple piece of syntax that turned a 30 minute WebEx into a 2 hour ordeal. I learned a good lesson about SnapMirror during this engagement, though, and I’d like to share it.
The SnapMirror of these three volumes were actually for a data migration because the source filer is being decommissioned. The general steps required in the engagement today were as follows:
<> Run a cable between what will be the dedicated replication links on each filer
<> Configure each interface with IP settings
<> Ensure SnapMirror is licensed and enabled on each filer
<> Configure /etc/hosts and /etc/snapmirror.allow files on source filer
<> Configure /etc/hosts and /etc/snapmirror.conf files on destination filer
<> Initialize the baseline replicaction
