Setting the Stage Type

After installing the GUI, you can leave the stage type to SL zoning (segmented loop) or change it to FLS-IO Transfer (IOT) mode.

SL zones enable you to divide the SL ports into multiple zones that define which ports will communicate with each other. Communications occur only between ports in the defined SL zone.

The default state type is SL zoning. IOT mode allows F-port, T-port, and TL-port configuration. Only switches in IOT mode can be cascaded together.

▼To Change SL Zoning to FLS-IO Transfer (IOT)

1.In the Fabric window, enter the IP address of the switch in the IP Address Field. SANsurfer finds the switch and a gray Sun icon is displayed in the status box.

If a red Sun icon is displayed in the Status box, SANsurfer did not find the switch. If the red Sun icon appears, check the following:

a.Does the switch have power?

b.Is the Ethernet cable plugged into the switch?

c.Is the IP address on the switch the same as the IP address in the IP Address Field in SANsurfer?

d.Do you have access to the switch from your subnet?

2.When the gray Sun icon appears, select it. The Topology window opens.

3.In the Topology window, select Special.

4.From the Special menu, select Change Stage Type.

Changing the stage type is a disruptive event. When the stage type on one switch changes, all the switches in the Fabric change to the same stage type, and each switch resets.

5.When the prompt appears to continue, choose Yes. After the reset, the display returns to the Fabric window.
