2. Use the Fabric list to select the fabric you want to configure.
NOTE
(Fabric OS switches only) All switches in a fabric must be running Fabric OS version 5.3 or later.
If a Fabric OS version earlier than version 5.3 is present in the topology, the fabric is not listed.
3. Select the FMS Mode check box to manage the fabric by a host-based management program
using FICON CUP protocol.
If you select FMS Mode, each switch is checked for a CUP license. Any switches that do not
have a CUP license are listed, with a reminder that a CUP license is necessary to communicate
with the FICON Management Server.
4. Select the DLS check box to enable Dynamic Load Sharing (DLS) or Lossless DLS only on
switches that support lossless DLS. For more information, refer to
page 1196. You must enable DLS to select routing policies.
5. Select one of the following options to enable port-based, exchange-based, or device-based
routing on switches:
•
Port-Based, enables port-based routing on 4 Gbps platform switches.
•
Exchange-Based, enables exchange-based routing for the fabric if all switches are 8 Gbps
or greater platforms running Fabric OS 6.4 or later. If these requirements are not met, an
error message displays.
•
Device-Based, enables device-based routing for the fabric if all switches in the fabric are 8
Gbps or greater platforms running Fabric OS 7.1 or later. If these requirements are not
met, an error message displays.
NOTE
Either exchange based routing, port based routing, or device-based routing is enabled on all
switches of the selected fabric. You cannot enable a mixed routing policy.
6. Click OK if you want to proceed.
A warning message displays listing the switches of the selected fabric that are to be disabled
and re-enabled in order to enable the desired routing policy and IDID.
7. Click Yes to continue.
If configuration is successful, a confirmation message displays.
If FMS Mode was selected, each switch is checked for a CUP license. Any switches that do not
have a CUP license are listed, with a reminder that a CUP license is necessary to communicate
with the S/B FICON Management Server.
NOTE
FMS mode cannot be enabled on switches running Fabric OS 7.0 and later unless the switches
have an active CUP license.
Enabling DLS
Consider the following when enabling Dynamic Load Sharing (DLS) in
:
•
DLS requires DLS support on the switch. Lossless DLS requires Lossless DLS support on the
switch.
