setup - update filer configuration
setup
setup queries the user for the basic filer configuration parameters such as hostname, IP address, and timezone. It installs new versions of /etc/rc, /etc/hosts, /etc/exports, /etc/resolv.conf, /etc/hosts.equiv, and /etc/dgateways to reflect the new configuration. When setup completes, the configuration files have been been updated, but their new contents do not take effect until the filer is rebooted (see na_reboot(1)). The old contents of the configuration files are saved in rc.bak, exports.bak, resolv.conf.bak, hosts.bak, hosts.equiv.bak, and dgateways.bak.
One piece of information that setup requests is the name and IP address for adminhost. In /etc/exports, adminhost is granted root access to / so that it can access and modify the configuration files in /etc. All other NFS clients are granted access only to /home. If no adminhost is specified, then all clients are granted root access to /. This is not recommended for sites where security is a concern.
If an adminhost is specified, then an additional line is added to the /etc/hosts file to point the default mailhost to the adminhost. This is used by the autosupport daemon (see na_autosupport(8)) to send email notification.
If a default gateway is provided to setup, it will be used in /etc/rc to specify a default route (see na_route(1)), and will also be used as the first entry in /etc/dgateways.
The hostname that is provided to setup is used to construct default names for all of the configured network interfaces. Ethernet interfaces are given names hostname-0, hostname-1, and so on. The FDDI interfaces are named hostname-f0, hostname-f1, and so on, and the ATM interfaces are named hostname-a0, hostname-a1, and so on.
After a takeover, you can enter the setup command in partner mode to configure the failed filer. However, only the network interfaces on the failed filer that were taken over appear in the prompts displayed by setup. For example, if the e1 interface on the failed filer was not configured and taken over by the live filer, the setup command does not prompt you for the IP address of the e1 interface.

, na_partner(1), na_reboot(1), na_dgateways(5), na_exports(5), na_hosts(5), na_hosts.equiv(5), na_resolv.conf(5), na_rc(5), na_autosupport(8)Some Ethernet boards determine the media type automatically. It is not strictly necessary to specify the media type for them, but it is best to do so anyway, in case the board is replaced with one that does not determine media type automatically.
