Oops. Sorry. Had Clariion on the brain. Check your SAN zones, then your Symmetrix masking. Make sure each LUN is masked as the same Host LUN ID on all of the host HBA's.
I had a similar problem. Tresspass the Clariion LUN(s) to the other SP. That should fix the issue with prtvtoc. Then rescan the LUN(s) (vxdctl enable) and you should be able to initialize them.
