Configuring Multichannel
Note: If your adapter has multichannel enabled and also supports IBM Virtual Fabric
Mode or IBM Unified Fabric Protocol Mode, refer to “Configuring Multichannel
for IBM Adapters” on page 1553 for additional information. If multichannel is
disabled or not supported on the adapter, refer to “Configuring Ports When
Multichannel is Disabled or Not Supported” on page 1540.
Enabling Multichannel
Multichannel, or UMC, provides the ability to configure multiple physical functions or
I/O channels for each physical adapter port. For additional information on
multichannel support, see the Emulex Universal Multichannel Reference Guide.
Notes:

When multichannel 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.

Multichannel functionality is only supported on OneConnect adapters running
in 10 Gb or 40 Gb mode. The 1 Gb mode does not support multichannel.

SR-IOV is not available when multichannel is enabled.
To enable multichannel:
1. From the Configure Controller screen, use the up or down arrow keys to select
MultiChannel.
2. Use the left or right arrow keys to enable multichannel.
