Hi.  Did you reboot or run ‘/etc/init.d/PowerPath start’ after you completed the installation? Thanks, Brion

Medet · Answer

Yes, sure.I downloaded the driver from Emulex site. Installation was complete without error.In the guide from EMC I found:The Emulex v8.x-series lpfc and lpfcdfc drivers may be installed onto a Linux host using the installer script packaged along with the driver sources.Downloaded the driver include only lpfc, I think I should install lpfcdfc, but I don't know where I can get this.

PowerPath will not display anything until the host has been added to a storage group and one or more LUNs have been presented as well.  Also double check that Failover mode is set to 1.

Conor · Answer

You need to add a LUN to the storage group with a Host LUN ID of 0

Looks like you are currently only seeing LUNz devices, indicating that you have connectivity to the array buit no LUNs in the SG.
