Table 7. Example worksheet for single host server with dual port iSCSI NICs (continued)
Management IP
Server iSCSI NIC 1 172.2.96.46
ME4024 controller A port 1 172.2.101.128
ME4024 controller B port 1 172.2.201.129
ME4024 controller A port 3 172.2.103.128
ME4024 controller B port 3 172.2.203.129
Subnet Mask 255.255.0.0
The following instructions document IPv4 configurations with a dual switch subnet for network redundancy and failover. It does not cover
IPv6 configuration.
Attach hosts to the storage system
1. Ensure that all network adapters have the latest supported firmware and drivers as described on the Dell Support portal.
2. Use the iSCSI cabling diagrams to cable the host servers to the switches or directly to the storage system.
Assign IP addresses for each network adapter connecting to the
iSCSI network
CAUTION:
The IP addresses must match the subnets for each network, so ensure that you correctly assign IP addresses
to the network adapters. Assigning IP addresses to the wrong ports can cause connectivity issues.
NOTE: If using jumbo frames, they must be enabled and configured on all devices in the data path, adapter ports,
switches, and storage system.
For RHEL 7
1. From the server terminal or console, run the nmtui command to access the NIC configuration tool (NetworkManager TUI).
2. Select Edit a connection to display a list of the Ethernet interfaces installed.
3. Select the iSCSI NIC that you want to assign an IP address to.
4. Change the IPv4 Configuration option to Manual.
5. Using the planning worksheet that you created in the “Prerequisites” section, provide the subnet mask by entering the NIC IP address
using the format x.x.x.x/16. For example: 172.1.96.46/16
6. Configure a gateway, if appropriate.
7. Select IGNORE for the IPv6 Configuration.
8. Check Automatically connect to start the NIC when the system boots.
9. Select OK to exit Edit connection.
10. Select Back to return to the main menu.
11. Select Quit to exit NetworkManager TUI.
12. Ping the new network interface and associated storage host ports to ensure IP connectivity.
13. Repeat steps 1-12 for each NIC you are assigning IP addresses to.
For SLES 12
1. From the server terminal or console, run the yast command to access the YaST Control Center.
2. Select System > Network Settings.
3. Select the iSCSI NIC that you want to assign an IP address to, then select Edit.
4. Select Statically Assigned IP Address.
5. Using the planning worksheet that you created in the “Prerequisites” section, enter the NIC IP address. For example: 172.1.96.46
6. Using the planning worksheet that you created in the “Prerequisites” section, enter the NIC subnet mask. For example: 255.255.0.0.
7. Select Next.
8. Ping the new network interface and associated storage host ports to ensure IP connectivity.
