Hi,
If they are standalone and not UCSM managed you can configure IPMI and use fence_ipmilan.

The above information is now outdated.
Version 4.1 of Red Hat Virtualization is current and the referenced Red Hat documentation link is a broken URL.
How can IPMI or cisco_ucs fence agents be used with this series of hardware, Cisco UCS C220 M3 ?

Not sure if it's still the issue for you - but here's I resolved it. It's a bit dirty workaround and redhat is already working on it.
You need to setup hexadecimal-encoded key for IPMIv2 authentication which is set on CIMC IPMI over LAN settings via Admin>Communication services as first thing.
Then you need to modify /sbin/fence_ipmilan file.
So, backup /sbin/fence_ipmilan in-case you need to replace it back
1) Please edit: /sbin/fence_ipmilan (with your favourite editor)
2) Move to line number 35, and add following just below the line:- cmd = options["--ipmitool-path"]. cmd += " -y (your hex key here)"
For reference, the ipmitool command that worked was as below:
~~~ # ipmitool -I lanplus -y $(hexadecimal-encoded Kg key for IPMIv2 authentication) -H <192.168.0.x> -U USERNAME -P PASSWORD -L Administrator chassis power status
Chassis Power is on
Then in RHV GUI > Hosts > Edit host > Power Management > Add/Edit agent .. and you need to add following options..
lanplus=true,power_wait=4
Good luck ;)
