Can not connect EMC

I have a EMC cx300 , I have installed powerpath , naviagent to the Redhat server , direct connect to the server , it works fine before .

I have reboot these two device , then found that the EMC device is not connected to the server , just found there are many devices ( emcpowera  , emcpowerb , emcpowerc ...... ) in /dev , I tried to remove these devices and reboot them , but still not work , can advise what can I do ?

Re: Can not connect EMC

if you check connectivity status in CX300, is your host logged-in ?
