Configuring Virtual Fabrics
19
•
Logical switches in an edge fabric connected to an FC router
•
A logical switch in InteropMode 2 or InteropMode 3
•
The logical switch has VE_Ports and is running Fabric OS 6.4.x or earlier
•
The logical switch has lossless DLS and is running Fabric OS 7.0.x or earlier
NOTE
For switches running Fabric OS 7.0.0 or later, VE_Ports on the 8 Gbps Extension Blade are
supported on logical switches that use XISLs.
d. ( Optional ) To make the logical switch a base switch, clear the Base Fabric for Transport
check box and select the Base Switch check box.
The Base Fabric for Transport check box is not relevant for base switches because all base
switches can use XISLs.
e. ( Optional ) For Backbone Chassis only, select an option in the 256 Area Limit list to use
256-area addressing mode (zero-based or port-based) or to disable this mode (default).
The 256-area addressing mode can be used in FICON environments, which have strict
requirements for 8-bit area FC addresses.
6. Click the Switch tab and enter switch parameters.
a. Enter a name for the logical switch in the Name field.
b. Select either Decimal or Hex and enter a preferred domain ID for the logical switch.
In a FICON environment, select a domain ID that is not in use by the default or another
logical switch in the same chassis.
c. ( Optional ) Select the Insistent check box to not allow the domain ID to be changed when a
duplicate domain ID exists.
If you select this check box and a duplicate domain ID exists, the switch will segment from
the fabric instead of changing the domain ID.
NOTE
If you disable the Insistent Domain ID (IDID) on the FMS-enabled switches, the following
error message displays:
The operation cannot be performed. Disable HIF mode and try again.
7. Click OK on the New Logical Switch dialog box.
The new logical switch displays in the Existing Logical Switches list (already highlighted). This
logical switch has no ports.
The newly created logical switch has no ports. To assign ports to the logical switch, refer to
“Assigning ports to a logical switch” on page 685.
If the newly created logical switch is not part of a discovered fabric, then you must undiscover and
rediscover the switch.
•
To undiscover the physical chassis, refer to “Deleting a fabric” on page 45 for instructions.
•
To rediscover the physical chassis, refer to “Discovering fabrics” on page 37 for instructions.
When entering the IP address, use the IP address of the physical fabric.
