Setting Description
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 → 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. Click Save As to save the entire iSCSI sessions topology as a text file.
3. To end the session:
a) Select the session that you want to end, and then click End Session.
The End Session confirmation window is displayed.
a) Type yes to confirm that you want to end the iSCSI session.
b) Click OK.
NOTE: If you end a session, any corresponding connections terminate the link between the host and the
storage array, and the data on the storage array is no longer available.
NOTE: When a session is manually terminated using the MD Storage Manager, the iSCSI initiator software
automatically attempts to re-establish the terminated connection to the storage array. This may cause an
error message.
