Configuring Universal Multichannel
Note: UMC is only available on OCe11100-series and OCe14000-series adapters.
Note: If your adapter has Multichannel Mode enabled and also supports IBM Virtual
Fabric Mode or IBM Unified Fabric Protocol Mode, refer to “Configuring
Multichannel for IBM Adapters” on page 1649 for additional information. If
Multichannel Mode is disabled or not supported on the adapter, refer to
“Configuring the Controller When Multichannel is Disabled or Not Supported”
on page 1640.
UMC provides the ability to configure multiple PCI functions or I/O channels for each
adapter port. For additional information on UMC support, see the Emulex Universal
Multichannel Reference Guide.
Note: When UMC is enabled, you must configure the multichannel settings
(minimum and maximum bandwidths) for iSCSI and FCoE storage functions in
the NIC BIOS before they can be configured further from their respective
utilities (iSCSI or FCoE BIOS). Otherwise, the Logical Link for that function will
still show as down, and you will not be able to log into targets or find LUNs
behind those targets.
Note: Multichannel functionality is only supported on OneConnect adapters running
in 10 Gb mode. The 1 Gb mode does not support UMC.
If multichannel functionality is supported on your system, the Emulex UEFI NIC utility
enables you to perform the following tasks:

Enable or disable multichannel functionality (Multichannel Mode)

View the current controller configuration

Configure the minimum and maximum bandwidth for each channel

Configure the LPVID for each channel
Note: Your system may not support all multichannel options.
Note: For OCe14000-series adapters, the Emulex NIC configuration utility displays all
of the functions on a port, regardless of whether the system supports ARI or
not. For additional information on ARI, see “ARI Support” on page 1645.
To enable multichannel support:
1. On the Emulex NIC Selection screen (Figure 11-2), select Multichannel Mode and
press <Enter>. The Multichannel Mode pop-up menu appears.
2. Select Enable to activate multichannel support and press <Enter>.
