The answer is to remove the DGC LUNZ hardware ID from MPIO's control in Windows and restart the OS.  I had added all of the discovered DGC hardware IDs after presenting LUNs from Array A.  From my understanding, LUNZ is a placeholder LUN that is presented to the host in order for it to see the array, login, register, etc.  There are numerous articles saying to add all DGC device types to MPIO, but DO NOT add LUNZ to MPIO!!  *Note:  This came from my own trial & error vs. EMC support.  They were not helpful on this one.  Tim
Hi, all!  We have 2 dual-port FC HBAs and each one connects to a separate VNX 5300 direct-attached.  Navi host agent registers on Array A just fine, but it doesn't on Array B.  I have the agent.config set with this, but am not having any luck:  User system[NAME]-spa-ip User system[NAME]-spb-ip User system[NAME]-spa-ip User system[NAME]-spb-ip  The WWNs are logged in to Array B, but not registered.  Everything works fine if I manually register the host on Array B, but I'd prefer that Navi host agent register for me to get the OS, status, and all of that good stuff.  *Note:  The host and all array SPs are on the same VLAN.  I have an open SR, but EMC support has yet to be helpful on this one.  The first support agent said that a host can't be attached to two arrays - lol.  Once you get someone good, their shift ends and the SR goes to limbo and have to keep re-assigning!  Any ideas?  Any help is appreciated.  Thanks! Tim
