SPARC: Setting Up an NVRAM Alias to Automatically Boot by Using DHCP
In Oracle Solaris 11, DHCP is the network configuration boot strategy that is used when booting from the network to install Oracle Solaris. To boot a system from the network with DHCP, a DHCP boot server must be available on your network.
You can specify that a SPARC based system boot by using the DHCP protocol when you run the boot command. Or, you can save the information across system reboots at the PROM level by setting up an NVRAM alias.
The following example uses the nvalias command to set up a network device alias for booting with DHCP by default:
ok nvalias net /pci@1f,4000/network@1,1:dhcp
As a result, when you type boot net, the system boots by using DHCP.
 | Caution - Do not use the nvalias command to modify the NVRAMRC file, unless you are very familiar with the syntax of this command and also the nvunalias command. |
