Administrator Guide

• 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.
6. Perform one of the following:
• To save your settings and continue configuring your system, click Apply.
• To save your settings and close the panel, click Apply and Close.
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.
• Command Line Interface (CLI). An advanced-user interface that is used to manage the system and can be used to write scripts.
SSH (secure shell) is enabled by default. The default port number for SSH is 22. Telnet is disabled by default, but you can enable it
in the CLI.
• Storage Management Initiative Specification (SMI-S). Used for remote management of the system through your network. You can
enable use of secure (encrypted) or unsecure (unencrypted) SMI-S:
○ Enable. Select this check box to enable unencrypted communication between SMI-S clients and the embedded SMI-S
provider in each controller module using HTTP port 5988. Clear this check box to disable the active port and use of SMI-S.
○ Encrypted. Select this check box to enable encrypted communication, which disables HTTP port 5988 and enables HTTPS
port 5989 instead. Clear this check box to disable port 5989 and enable port 5988. This is the default.
NOTE: SMI-S is not supported for a system with 5U84 enclosures.
• Service Location Protocol (SLP). Enables or disables the Service Location Protocol (SLP) interface. SLP is a discovery protocol
that enables computers and other devices to find services in a LAN without prior configuration. This system uses SLP v2.
• File Transfer Protocol (FTP). A secondary interface for installing firmware updates and downloading logs.
• SSH File Transfer Protocol (SFTP). A secure secondary interface for installing firmware updates, downloading logs, and installing
security certificates and keys. All data that is sent between the client and server is encrypted. SFTP is enabled by default. If
selected, specify the port number to use. The default is 1022.
• Simple Network Management Protocol (SNMP). Used for remote monitoring of the system through your network.
• Service Debug. Used for technical support only. Enables or disables debug capabilities, including Telnet debug ports and privileged
diagnostic user IDs.
NOTE:
Properly shut down the debug console by using the CLI command set protocols debug disable. Do not just
close the console directly or by using the CLI command exit.
