EVA to 3Par Online Import -- volume accessible though one peer port

 

I'm working on doing an EVA to 3Par online import between an EVA 4400 and 3Par V400 using CommandView

10.3.6.150143.  I'm 95% certain I have the zoning correct; the tool passes all the pre-flight checks and only fails at the final migration screen with the following error:  "Volume <UUID" is only accessible through one peer port":

I found a troubleshooting article that advised checking the targets on the 3Par as well as manually presenting the EVA LUN to the 3Par directly.  I did that and everything looks good in the command output.

HPN-3Par-3 cli% showtarget

Re: EVA to 3Par Online Import -- volume accessible though one peer port

You are using the peer ports on destination from same node 0. The ports 0:2:1 & 0:2:2. This is not supported. You need to use the ports from adjacent node pairs for peer motion Example would be 0:2:1 & 1:2:2. Correct the zoning and you will be able to migrate the volumes.
