I have set up a Dell R620 with iDRAC7 Enterprise – where I have bonded LOM1 and LOM2, and connected them to two different switches for failover.
When the server is powered on, I can access the idrac and do power cycle, read power status, but when I reboot the server, I can't access the idrac with racadm og ipmitools (CentOS).
Do I have to use the dedicated NIC on the idrac7 for power management when the server is powered off?

I got an answer from Dell Support on this.
It is normal that one cannot access the iDRAC for some period during reboot, because the "NICs must also reboot during a reboot"

A poweron / powercycle when the server is down is supported if the switch is configured to support Wake-On-LAN.
