Network tab—Configure controller network ports
You can manually set static IP address parameters for network ports or you can specify that IP addresses be set automatically. IP
addresses can be set automatically using DHCP for IPv4 or Auto for IPv6, which uses DHCPv6 and/or SLAAC.
NOTE: If you used the default 10.0.0.2/10.0.0.3 addresses to access the guided setup, consider changing those IPv4
addresses to avoid an IP conflict if you have more than one ME4 Series array on your network.
When setting IP values, you can choose either IPv4 or IPv6 formatting for each controller. You can also set the addressing mode and IP
version differently for each controller and use them concurrently. For example, you could set IPv4 on controller A to Manual to enable
static IP address, and IPv6 on controller B to Auto to enable automatic IP address.
When using DHCP mode, the system obtains values for the network port IP address, subnet mask, and gateway from a DHCP server if
one is available. If a DHCP server is unavailable, current address is unchanged. You must have some means of determining what addresses
have been assigned, such as the list of bindings on the DHCP server. When using Auto mode, addresses are retrieved from both DHCP
and Stateless address auto-configuration (SLAAC). DNS settings are also automatically retrieved from the network.
Each controller has the following factory-default IP settings:
• IP address source: Manual
• Controller A IP address: 10.0.0.2
• Controller B IP address: 10.0.0.3
• IP subnet mask: 255.255.255.0
• Gateway IP address: 10.0.0.1
When DHCP is enabled in the storage system, the following initial values are set and remain set until the system can contact a DHCP
server for new addresses:
• Controller IP addresses: 169.254.x.x (where the value of x.x is the lowest 16 bits of the controller serial number)
• IP subnet mask: 255.255.0.0
• Gateway IP address: 10.0.0.0
169.254.x.x addresses (including gateway 169.254.0.1) are on a private subnet that is reserved for unconfigured systems and the
addresses are not routable. This prevents the DHCP server from reassigning the addresses and possibly causing a conflict where two
controllers have the same IP address. As soon as possible, change these IP values to proper values for your network.
For IPv6, when Manual mode is enabled you can enter up to four static IP addresses for each controller. When Auto is enabled, the
following initial values are set and remain set until the system can contact a DHCPv6 and/or SLAAC server for new addresses:
• Controller A IP address: fd6e:23ce:fed3:19d1::1
• Controller B IP address: fd6e:23ce:fed3:19d1::2
• Gateway IP address: fd6e:23ce:fed3:19d1::3
CAUTION:
Changing IP settings can cause management hosts to lose access to the storage system after the changes
are applied in the confirmation step.
Set IPv4 addresses for network ports
Perform the following steps to set IPv4 addresses for the network ports:
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 IPv4 tab.
3. Select the type of IP address to use for each controller. Choose Source > manual to enter static IP addresses or choose Source >
DHCP to have the system automatically obtain IP addresses from a DHCP server.
4. If you chose manual, enter the unique IP address, IP mask, and gateway address for each controller, and then record the IP addresses
that you entered.
NOTE:
The following IP addresses are reserved for internal use by the storage system: 169.254.255.1, 169.254.255.2,
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.
5. 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 is displayed.
