So I have a RHEL 6 server configured with the correct NTP server. Correct? At least that is I what thought. But it will not sync with the NTP server.

I have the name of an UCS B series blade server that I need to configure. I need to locate the blade on an UCS Manager.
We can login to the UCS Manager GUI but that will take a long time. We can do it much quicker on the CLI. Ssh to the UCSM and and run these commands
UCSM-A# show service-profile status | grep server_name
This will work if the service-profile matches the server. But the service profile may be named differently ( which I hate) than the server name. Try this
UCSM-A /org # scope org GIS_HADOOP
UCSM-A /org # show service-profile detail | grep 'User Label:' | grep server_name
Hopefully, the user label should have the server name. The user label is what you see within bracket next to profile name in the UCSM GUI.
