No just a single host. I didn't see any documentation that said you need two or more
hosts. You could be right.
I did some further testing by installing ipmitool on my laptop.
[root@lt ~]# ipmitool -v -I lanplus -H 172.30.50.2 -U ADMIN session info all
Password:
session handle : 0
slot count : 16
active sessions : 1
user id : 2
privilege level : ADMINISTRATOR
session type : IPMIv2/RMCP+
channel number : 0x01
Maybe a one of the DEVs could chime in and confirm if this is expected behavior?
