/etc/rc file is a very important configuration file that is required by ONTAP while booting, it must be editted very carefully.
There are two better ways to edit /etc/rc file
map the <filer_name>\C$ to your administration machine and edit the etc>rc file using a text editor
telnet to the filer ----> issue rdfile /etc/rc, copy the contents to a text editor on your administration machine, include the entries for VLAN -----> issue wrfile /etc/rc on the telnet window -----> copy the contents from your text editor and paste on the telnet window -------> press Enter and CTRL + C. This will save the changes made to /etc/rc file
why is it necessary to add it in /etc/rc file? After we got a new FAS2040, we run the initial setup with an NetApp technician were network config was done (e0a). A Few weeks later we configured an additional nic (e0b) via CLI. After a reboot the new configuration on e0b didn't exists.
Is for that an explanation why it's working for e0a and not for e0b??
