no valid mapping entries in conf file

Hello

I have a Solaris 10 Sparc box installed with Emulex Lp1100 HBAs that is connected to a CX300.

I have set up the Emulex leadville drivers and can see the CLARiiON LUNs in \dev\dsk as c1t d0s0 etc

I have installed PowerPath 5.2 to multipath the devices, but I receive an error when I run powercf -q
NO valid mapping entries in conf file
also
powermt display dev=all
returns no results.

The box was built cleanly from scratch so it has never had an earlier version of PowerPath on it. I have tried removing PowerPath using the /etc/emcp_cleanup script and then reinstalling it, but this hasn't worked.

Any ideas?

Thanks,

Richard.
