How the /etc/hosts file
works
Data ONTAP uses the /etc/hosts
file to resolve host names to IP
addresses. You need to keep the /etc/hosts
file up-to-date.
Changes to the file take effect immediately.
When Data ONTAP is first installed, the /etc/hosts
file is
automatically created with default entries for the following
interfaces:
- localhost
- All interfaces on your storage system
Note: The /etc/hosts
file resolves the host names for the storage
system on which it is configured. This file cannot be used by other
systems for name resolution.
For more information on file format, see the na_hosts(5) man
page.
You can add IP address and hostname entries in the /etc/hosts
file in the following two ways:
- Locally—You can add entries at the command line or by using FilerView.
- Remotely—If the file has many entries and you have access to an NIS makefile master, you can use the NIS makefile master to create the /etc/hosts file. This method prevents errors that might be caused by editing the file manually.
