You will need to make sure to have the ipspaces (for multistore) on both NetApps, and all ifgroups/vlans created on both NetApps. This is where most people fail during the setup and CFO's will result in nothing working. When you are done with your setup, run the HA-Config-Checker.exe program that is available on the NOW site.</P></BODY></HTML> Tue, 10 Jan 2012 21:58:44 GMT https://community.netapp.com/t5/ONTAP-Hardware/HA-Pair-Do-I-need-to-duplicate-my-igroups-and-initiators/m-p/13490#M953 ryanbeaty 2012-01-10T21:58:44Z Re: HA Pair - Do I need to duplicate my igroups and initiators? https://community.netapp.com/t5/ONTAP-Hardware/HA-Pair-Do-I-need-to-duplicate-my-igroups-and-initiators/m-p/13497#M954 <HTML><HEAD></HEAD><BODY><P>Awesome.
