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 on 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.

3. To save the entire iSCSI sessions topology as a text file, click Save As
