DirectPDMapping

I looked at the CMDTool2 manual for the RMT3CB080 Raid controller and found the syntax to change the DirectPDMapping setting, default is off. Every time I issue the command to turn it on I get an exit code 0x1. On LSI controllers I have successfully done this in EFI. I tried MegaCLI, StorCLI and CmdTool2 in EFI and DOS, no luck. In the StorCLi utility it replies that the directpdmapping failed for set cmd Error code 3. Has anyone else seen this behavior?

Thanks,

Scott
