Note: These rules apply when NParEP mode is enabled or disabled.

The first partition on a port is always NIC.

Up to sixteen partitions can be configured on NPar adapters when NParEP
Mode is enabled.

When NPar is enabled, RoCE cannot be configured on any partition.

A storage protocol can be assigned to any of the second through fourth
partitions. Any partitions above the fourth partition can only be assigned NIC
or None.

Any other than the first partitions on a port can be set to NIC or None.

The total of the minimum bandwidths of the enabled functions for each port
must add up to 100 percent. The maximum bandwidth for each partition must
be greater than, or equal to, the minimum bandwidth for that partition.

After changing the NPar configuration and applying the changes, except for
bandwidth changes, a reboot is required to activate the new configuration.
NPar Bandwidth Settings
Similar to UMC, a minimum and maximum bandwidth is assigned to each enabled (i.e.
not set to None) partition. The sum of the minimum bandwidths must add up to 100
percent. The maximum bandwidth for each partition must be equal to or greater than
the minimum bandwidth on that partition and no larger than 100 percent.
Unlike UMC, if the minimum and maximum bandwidths are set to 0, the logical link on
the adapter is not brought down. A small of amount of data will pass through the port
for that partition when bandwidth is available. Bandwidth changes take effect
immediately. A reboot is not required.
