Hi,       Host registration to a CLARiiON array is done in band, that is, through the Fibre Channel connection.  In order for a host to register successfully a LUNZ device must be successfully presented to the host for every path that is zoned to the array.  A LUNZ is a logical device that allows host software, that is, the Navisphere agent to pass commands to the array.  LUNZ takes the place of HLU 0 until real physical storage is allocated. The LUNZ devices are created based on the arraycommpath setting in Navisphere.       Please refer to Primus article "emc125015" to register Navisphere agent on Various Host OS platforms.
Navisphere Agent will not register host with CLARiiON array
I'm unable to register Navisphere agent on the host automatically, could 
someone please let me know if it can be done manually?
