Channel Management Commands
346
The number of channels, the number of channels that need to be specified, and the
number of bandwidth combinations that need to be specified depend upon the adapter
model. See “CMGetParams” on page 342 to determine how many bandwidths need to
be specified for a port by looking at the number of functions indicated in the “Func #”
column of the output.
The total of the minimum bandwidths for the enabled channels or partitions (NPar)
must add up to 100. An exception to this rule is for UMC and SIMODE configurations
when both the minimum and maximum bandwidth for all channels are 0; effectively
bringing down the logical link on all channels. The maximum bandwidth must be
greater than or equal to the minimum bandwidth for that channel or partition (NPar)
up to a maximum value of 100.
Notes

If too many or too few minimum and maximum bandwidth combinations are
provided, an error is generated.

This command fails with an error message if the configured multichannel mode
is vNIC1, UFP or None.

For UMC, the UMCSetBW command can still be used instead of CMSetBW.

A reboot is not required to change the channel bandwidths when channel
management is enabled or when currently running NPar on the adapter.

If a channel's protocol is configured to "None", the minium and maximum
bandwidth must be 0.
Supported By
