LPAR and CFGMGR

I have a P570 that for some reason is not allowing the P1-T6 NIC to be recognized. I have confirmed from the HMC that it is set for the LPAR, but when I do a cfgmgr, it won't recognize it. It though is recognizing the slot cards just fine which are P1-C3 for one shelf and P1-C3 of another shelf.

Any help is greatly appreciated.

Reboot the lpar (shutdown -Fr) and you might find it mysteriously appears. Had the same problem with a CD drive!
