Using the setup command

When to use the setup command

Perform the steps described in this section after you have read and considered the available setup methods described in Choosing a setup method.

Attention
The setup command can be run at any time from the storage system command line. However, it is usually run at initial system configuration when it is invoked automatically. Do not run the setup command unless you want to completely reconfigure your system. For more information about the setup command, see the setup(1) man page.

Designating an administration host

During the setup process, you are prompted to designate an administration host. The host you specify (if any) is the machine that you intend to use for storage system administrative tasks. Consider the following information when deciding whether you want to designate an administration host.

When you do not designate an administration host

The storage system's root file systems are available to all network clients.
Any users can gain access to the storage system's root file system and change or remove storage system configuration files in the /etc directory.

When you designate an administration host

You limit storage system administration to the host you specify.
You can add additional administration hosts after setup by modifying the storage system's NFS exports and CIFS shares.
The storage system's root file system (/vol/vol0 by default) is accessible to that administration host in the following ways:
- As a share named C$, if the storage system is licensed for the CIFS protocol
- By NFS mounting, if the storage system is licensed for the NFS protocol
  For example, to mount storage_sys:/vol/vol1/MyQtree on a UNIX host, you would enter the following command:
  
  mount filer:/vol/vol1/MyQtree/mnt/storage_sys /MyQtree

Running the setup command

To use the setup command, complete the following steps.

Step	Action
1	Boot the storage system following the instructions in the Installation and Setup Instructions for your hardware platform. Result After the storage system boots, Data ONTAP begins discovering the devices, interfaces, and licenses installed in the system. Data ONTAP displays messages on the console and starts the `setup` command, prompting you to enter setup information. Note Storage system components and external switches must be powered up in the correct order. This is especially important the first time you boot your system to ensure that initial configuration is completed correctly.
2	Answer the prompts using the information you gathered earlier. See Chapter 2, Information Gathering.
3	When prompted, enter a host name and IP address to designate the storage system administration host machine, or press Enter to allow storage system administration from all clients. Attention If you do not designate an administration host, the storage system's root file systems are available to all network clients. See Designating an administration host for administrative host considerations. To remove an administration host you've designated, enter the following command at the storage system prompt after setup is complete: options admin.hosts ""
4	Enter `n` to continue using the `setup` command when you receive the following prompt. Would you like to continue setup through the Web interface?
5	When setup is complete, to transfer the information you've entered to the storage system, enter the following command, as directed by the prompt on the screen. `reboot` Note If you do not enter `reboot`, the information you entered does not take effect.
6	If you are configuring a pair of storage systems in a cluster and have not configured the other storage system, set up the other storage system in the cluster.
