Looking back at your earlier post ... when you said the health status is not showing anything, do you mean the "Hardware Status" tab as seen from the vSphere Client?
Any chance you also installed the Emulex CIM providers? I've heard of problems having both HP's and Emulex CIM providers on the same host.
Also, make sure wsman is running on the host:
# /etc/init.d/wsman status
openwsmand is running
Finally, check what port(s) wsman is listening:
~ # esxcli network ip connection list | grep ws
tcp 0 0 127.0.0.1:8889 0.0.0.0:0 LISTEN 9715 openwsmand
