Dell EMC PowerVault MD 34XX/38XX Series Storage Arrays Administrator's Guide

Configuring the iSCSI host ports

The default method for configuring the iSCSI host ports, for IPv4 addressing, is DHCP. Always use this method unless your network does not have a DHCP server. It is advisable to assign static DHCP addresses to the iSCSI ports to ensure continuous connectivity. For IPv6 addressing, the default method is Stateless auto-configuration. Always use this method for IPv6.

1. In the AMW, select the Setup tab.
2. Select Configure iSCSI Host Ports.
   The Configure iSCSI Ports window is displayed.
3. In the iSCSI port list, select an appropriate RAID controller module and an iSCSI host port.
   The connection status between the storage array and the host is displayed in the Status area when you select an iSCSI host port. The connection status is either connected or disconnected. Additionally, the media access control address (MAC) of the selected iSCSI host port is displayed in the MAC address area.

   NOTE: For each iSCSI host port, you can use either IPv4 settings or IPv6 settings or both.
4. In the Configured Ethernet port speed list, select a network speed for the iSCSI host port.
   The network speed values in the Configured Ethernet port speed list depend on the maximum speed that the network can support. Only the network speeds that are supported are displayed.

   All of the host ports on a single controller operate at the same speed. An error is displayed if different speeds are selected for the host ports on the same controller.

5. To use the IPv4 settings for the iSCSI host port, select Enable IPv4 and select the IPv4 Settings tab.
6. To use the IPv6 settings for the iSCSI host port, select Enable IPv6 and select the IPv6 Settings tab.
7. To configure the IPv4 and IPv6 settings, select:
   • Obtain configuration automatically from DHCP server to automatically configure the settings. This option is selected by default.
   • Specify configuration to manually configure the settings.
   NOTE: If you select the automatic configuration method, the configuration is obtained automatically using the DHCP for IPv4 settings. Similarly for IPv6 settings, the configuration is obtained automatically based on the MAC address and the IPv6 routers present on the subnetwork.
8. Click Advanced IPv4 Settings and Advanced IPv6 Settings to configure the Virtual Local Area Network (VLAN) support and Ethernet priority.
9. Click the Advanced Port Settings to configure the TCP listening port settings and Jumbo frame settings.
10. To enable the Internet Control Message Protocol (ICMP), select Enable ICMP PING responses.
    The ICMP setting applies to all the iSCSI host ports in the storage array configured for IPv4 addressing.

    NOTE: The ICMP is one of the core protocols of the Internet Protocol suite. The ICMP messages determine whether a host is reachable and how long it takes to get packets to and from that host.
11. Click OK.
