You can find the following at this link: http://now.netapp.com/NOW/knowledge/docs/ontap/rel7261_vs/html/ontap/bsag/13...
Caution If you have a storage system cluster, and the cfmode of each system is single_image, then you must change the WWNN on both systems. If both systems do not have the same WWNN, hosts cannot access LUNs on the cluster.
To change the WWNN, complete the following step.
Step
Action
1
Enter the following command:
fcp nodename nodename
nodename is a 64-bit WWNN address.
Example
fcp nodename 50:a9:80:00:02:00:8d:ff
Just copy the WWNN of one of the systems and change the other node to the same one. It doesn't matter which one you take ...
I don't know if this is possible in production. I think you'll have to restart the fcp service to enable the change, but I'm not sure.
Grtz, Tom

The following FCP HBAs appear to be down 0a LINK NOT CONNECTED 0b LINK NOT CONNECTED
Hmm, what is the output of fcp show adapter?
Local FCP nodename does not match the cluster partner's FCP nodename.
And you are running in single_image mode just fine with other hosts?
That is really bizarre.
I'm not sure, if the nodenames are different you may want to try bringing down the fcp service and then try starting it up again to see if that helps.
Good luck,
Romeo
