Network booting x4100/x4200 using ipmitool
You can use the ipmitool command to reset an IPMI compliant server and force it to do a network (PXE) boot. In my case I am using it on a bunch of Sun x4200 M2 servers. This capability is very handy if you are trying to jumpstart or kickstat a server or group of servers. I wish I knew this method was available last month when I jumpstarted 50+ x4200s.
# echo $your_ilom_password > /tmp/pass
# chmod 400 /tmp/pass
# ipmitool -I lanplus -H $ilom_ip -U root -f /tmp/pass chassis bootdev pxe
Set Boot Device to pxe
# ipmitool -I lanplus -H $ilom_ip -U root -f /tmp/pass chassis power reset
