The /etc/rc file contains commands that the storage system executes at boot time to configure the system.
What startup commands do
Startup commands are placed into the /etc/rc file automatically after you run the setup command or the Setup Wizard.
Commands in the /etc/rc file configure the storage system to
1) Communicate on your network
2) Use the NIS and DNS services
3) Save the core dump that might exist if the storage system panicked before it was booted

Explanation of default /etc/rc contents
Description : hostname filerA
Sets the storage system host name to "filerA."

ifconfig e0 `hostname`-0
ifconfig e1 `hostname`-1
ifconfig a0 `hostname`-a0
ifconfig a1 `hostname`-a1
Sets the IP addresses for the storage system network interfaces with a default network mask.
The arguments in single backquotes expand to "filerA" if you specify "filerA" as the host name during setup. The actual IP addresses are obtained from the /etc/hosts file on the storage system root volume. If you prefer to have the actual IP addresses in the /etc/rc file, you can enter IP addresses directly in /etc/rc on the root volume.
