169.254.255.3, 169.254.255.4, and 127.0.0.1. Because these addresses are routable, do not use them anywhere in your
network.

Configure DNS settings
Perform the following steps to configure DNS settings:
1. Perform one of the following to access Network options:
● In the Home topic, select Action > System Settings, and then click the Network tab.
● In the System topic, select Action > System Settings, and then click the Network tab.
2. Select the DNS tab.
3. Enter a hostname in the Hostname text box to set a domain hostname for each controller module. Use the following naming
conventions:
● The name must differ for each controller.
● The name can have from 1 byte to 63 bytes.
● The name is not case-sensitive.
● The name must start with a letter and end with a letter or digit.
● The name can include letters, numbers, or hyphens; no periods.
4. Enter up to three network addresses for each controller in the DNS Servers fields.
The resolver queries the network in the order that is listed until reaching a valid destination address. Any valid setting is
treated as enabling DNS resolution for the system.
5. Specify up to three domain names for each controller in the Search Domains fields to search when resolving host names
that are configured in the storage system.
The resolver queries the network in the order that is listed until finding a match.
NOTE:
To reset Hostname to its default setting, select the Reset button for each controller. To clear the configured
DNS Servers and Search Domains, select the Clear DNS Settings button for each controller.

A confirmation panel appears.
7. Click Yes to save your changes. Otherwise, click No.
Enable or disable system-management settings
You can enable or disable management services to limit the ways in which users and host-based management applications can
access the storage system. Network management services operate outside the data path and do not affect host I/O to the
system. In-band services operate through the data path and can slightly reduce I/O performance.
To allow specific users to access the PowerVault Manager, CLI, or other interfaces, see Adding, modifying, and deleting users.
1. Perform one of the following to access the Services options:
● In the Home topic, select Action > System Settings, then click the Services tab.
● In the System topic, select Action > System Settings, then click the Services tab.
● In the banner, click the user panel and select Set Up System Services.
● In the Welcome panel, select System Settings, and then click the Services tab.
2. Enable the services that you want to use to manage the storage system, and disable the others.
● Web Browser Interface (WBI). The web application that is the primary interface for managing the system. You can enable
use of HTTP and/or HTTPS for increased security, or of both. If you disable both, you lose access to this interface.
