I was recently faced with the prospect of commissioning another 42
servers and needed to get the MAC addresses of both NICs of all server
for cobbler installs. So, I re-visited this issue and found a way to do
it - racadm racdump
The following command prints the MAC addresses for the DRAC and all
$ racadm -r $DRAC -u root -p calvin racdump | \
egrep '^MAC Address|^NIC. Ethernet'
MAC Address = a4:ba:db:11:38:2f
NIC1 Ethernet = a4:ba:db:11:38:2d
NIC2 Ethernet = a4:ba:db:11:38:2e
NIC3 Ethernet = N/A
NIC4 Ethernet = N/A
