Administrator Guide

• 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.
Advanced iSCSI host port settings
NOTE: Configuring the advanced iSCSI host ports settings is optional.
Use the advanced settings for the individual iSCSI host ports to specify the TCP frame size, the virtual LAN, and the network priority.
Setting
Description
Virtual LAN
(VLAN)
A method of creating independent logical networks within a physical network. Several VLANs can exist within a
network. VLAN 1 is the default VLAN.
NOTE: For more information about creating and configuring a VLAN with MD Support Manager, in
the AMW, click the Support tab, then click View Online Help.
Ethernet Priority The network priority can be set from lowest to highest. Although network managers must determine these
mappings, the IEEE has made broad recommendations:
• 0—lowest priority—default
• (1–4)—ranges from “loss eligible” traffic to controlled-load applications, such as streaming multimedia and
business-critical traffic
• (5–6)—delay-sensitive applications such as interactive video and voice
• 7—highest priority reserved for network-critical traffic
TCP Listening
Port
The default Transmission Control Protocol (TCP) listening port is 3260.
Jumbo Frames The maximum transmission units (MTUs). It can be set between 1501 and 9000 Bytes per frame. If the Jumbo
Frames are disabled, the default MTU is 1500 Bytes per frame.
NOTE: Changing any of these settings resets the iSCSI port. I/O is interrupted to any host accessing that port. You can
access the I/O automatically after the port restarts and the host logs in again.
Viewing or ending an iSCSI session
You may want to end an iSCSI session for the following reasons:
• Unauthorized access — If an initiator is logged on whom you consider to not have access, you can end the iSCSI session. Ending the
iSCSI session forces the initiator to log off the storage array. The initiator can log on if None authentication method is available.
• System downtime — If you need to turn off a storage array and initiators are logged on, you can end the iSCSI session to log off the
initiators from the storage array.
To view or end an iSCSI session:
1. In the AMW menu bar, select Storage Array > iSCSI > View/End Sessions.
2. Select the iSCSI session that you want to view in the Current sessions area.
The details are displayed in the Details area.
