OME 1.1 Discovery of iDRAC6 via WSMAN - can't see hardware information

I upgraded from OME 1.0.1 to OME 1.1 and I want to do agent less monitoring of servers.

Now I can inventory iDRAC7 with WSMAN, and see software and hardware info.

For iDRAC6 (version 3.40) on all servers I can't get any hardware info, but get software info. Health status is unknown (?).

I have some questions

1. For iDRAC7 do I have to set up SNMP traps to receive alerts, or alerts will came on other way?

2. How to get iDRAC6 to collect hardware info and alerting?
