I had the EXACT same issue on my AX4 I built.  You can try the following:  1. Login into the managed SP through Navi Express to reboot the other SP since this operation goes through the CMI link between the two SPs.2. Use the NMI button (or reseat the SP) to restart the SP. 3. Re-initalize the array completly. This is what I ended up having to do.  Ted
Hi,  I have just unboxed and installed a new AX4 and SP B is saying that is is unmanaged, it was working correctly before a system reboot I have since rebooted several times but I keep getting the same error.  Storage system management software can no longer manage the other storage processor (known as the peer) in this storage system. (0x743a)  Can anyone suggest what I can do to try to resolve this?  Cheers,  Joe
