How to maintain host-name information

Data ONTAP relies on correct resolution of host names to provide basic connectivity for storage systems on the network. If you are unable to access the storage system data or establish sessions, there might be problems with host-name resolution on your storage system or on a name server.

Host-name information can be maintained in one or all of the following ways in Data ONTAP:

•	In the /etc/hosts file on your storage system's default volume

•	On a Domain Name System (DNS) server

•	On a Network Information Service (NIS) server

If you use more than one of the resources for host-name resolution, the order in which they are used is determined by the /etc/nsswitch.conf file.
