The /etc directory is contained in the root directory. It stores storage system configuration files, executables required to boot the system, and some log files.
Attention: Do not delete any directories from the /etc directory unless instructed to do so by technical support personnel.
What the configuration files are
Configuration files affect the behavior of the storage system. You can use an editor on your administration host to edit some configuration files in the /etc directory.
How you edit configuration files
Data ONTAP does not include an editor. You cannot edit files by using the system console or by establishing a Telnet session to the storage system. You must use an editor from an NFS client or a CIFS client to edit storage system configuration files.
The /etc/messages file
By default, all system messages of level INFO and higher are sent to the console and to the /etc/messages file, which enables you to see a record of events on your storage system and use scripts to parse for particular events.
