Administrator Guide

The number of ports that are displayed depends on the configuration of the system.
CNC host ports can be configured as all FC or all iSCSI ports, or a combination of both. FC ports support use of qualified
8 Gb/s or 16 Gb/s SFPs. You can set FC ports to auto-negotiate the link speed or to use a specific link speed. iSCSI ports
support use of qualified 1 Gb/s, 10 Gb/s SFPs. or qualified 10 Gb/s Direct Attach Copper (DAC) cables. iSCSI port speeds are
auto-negotiated.
NOTE: For information about setting host parameters such as FC port topology, and the host-port mode, see the Dell EMC
PowerVault ME4 Series Storage System CLI Guide.
Configure FC ports
Perform the following steps to configure FC ports:
1. Perform one of the following to access the options in the Ports tab:
● In the Home topic, select Action > System Settings, then click Ports.
● In the System topic, select Action > System Settings, then click Ports.
2. From the Port Settings tab, set the port-specific options:
● Set the Speed option to the proper value to communicate with the host, or to auto, which auto-negotiates the proper
link speed. Because a speed mismatch prevents communication between the port and host, set a speed only if you need
to force the port to use a known speed.
● Set the Connection Mode to either point-to-point or auto:
○ point-to-point: Fibre Channel point-to-point.
○ auto: Automatically sets the mode based on the detected connection type.
3. 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.
4. Click OK.
Configure iSCSI ports
Perform the following steps to configure iSCSI ports:
1. Perform one of the following to access the options in the Ports tab:
● In the Home topic, select Action > System Settings, then click Ports.
● In the System topic, select Action > System Settings, then click Ports.
2. From the Port Settings tab, Set the parameters for the iSCSI ports:
● IP Address: For IPv4 or IPv6, the port IP address. For corresponding ports in each controller, assign one port to one
subnet and the other port to a second subnet. Ensure that each iSCSI host port in the storage system is assigned a
different IP address. For example, in a system using IPv4:
○ Controller A port 2: 10.10.10.100
○ Controller A port 3: 10.11.10.120
○ Controller B port 2: 10.10.10.110
○ Controller B port 3: 10.11.10.130
● Netmask: For IPv4, subnet mask for assigned port IP address.
● Gateway: For IPv4, gateway IP address for assigned port IP address.
● Default Router: For IPv6, default router for assigned port IP address.
3. In the Advanced Settings section of the panel, set the options that apply to all iSCSI ports:
● Enable Authentication (CHAP): Enables or disables the use of the Challenge Handshake Authentication Protocol
(CHAP). Enabling or disabling CHAP in this panel updates its setting in the Configure CHAP panel (available in the Hosts
topic by selecting Action > Configure CHAP. CHAP is disabled by default.
NOTE:
CHAP records for iSCSI login authentication must be defined if CHAP is enabled. To create CHAP records,
see Configuring CHAP.
● Link Speed:
○ Auto – Auto-negotiates the proper speed.
○ 1 Gbit/s – Forces the speed to 1 Gbit/sec, overriding a downshift that can occur during auto-negotiation with
1-Gbit/sec HBAs. This setting does not apply to 10 Gbit/sec HBAs.
