Table 4 – CNA Properties in DCIM_NICView 340
Personality Detail
NicMode Indicates if the NIC personality is enabled or disabled on the current partition
FCoEOffloadMode
Indicates if the Fibre Channel over Ethernet (FCoE) personality is enabled or
disabled on the current partition.
iScsiOffloadMode
Indicates if the Internet Small Computer System Interface (iSCSI) personality is
enabled or disabled on current partition
MaxBandwidth Indicates maximum bandwidth on current partition.
MinBandwidth Indicates minimum bandwidth on current partition.
WWPN Indicates World Wide Port Name of a port.
CNA devices allow a user to provide a range of bandwidth for each partition, which is represented in 341
terms of percentage of total bandwidth. 342
6.3 Changing personalities on a partition 343
User can enable or disable a personality of a partition by changing the corresponding attribute. Table 5 344
lists the attribute names that represent each personality. 345
Table 5 – Changing personalities on a partition 346
Personality AttributeName Detail
NIC NicMode
Enables or disables NIC personality on the
partition.
Fibre Channel Over Ethernet
(FCoE)
FCoEOffloadMode
Enables or disables FC personality on the
partition.
Internet Small Computer System
Interface (iSCSI)
iScsiOffloadMode
Enables or disable iSCSI personality on the
partition.
Use SetAttribute() or SetAttributes() method on an attribute to change its value. See Section 8.1 and 8.2 347
for more details. 348
6.4 Enabling or disabling a partition 349
There are four partitions on each port of a CNA device. Partition 1 cannot be disabled on any port. 350
Enabling any personality on a partition enables the partition. Disabling all the personalities on a partition 351
disables the partition (see section 6.3 for information to enable or disable a partition personality). 352
To disable partitioning functionality altogether on all ports simultaneously, set the NicPartitioning attribute 353
to Disabled. After the host system restarts, the CNA device will no longer expose multiple partitions to the 354
host system. Instead, a DCIM_NICView will be created for each port. See section 7.7.2 for more details. 355
6.5 Changing bandwidth on a partition 356
Use the MaxBandwidth and MinBandwidth attributes to change the bandwidth range of a partition. 357
MinBandwidth is the relative bandwidth allocated to a partition with respect to the entire port. Make sure 358
that the sum of all MinBandwidth should not be greater than 100% and MinBandwidth should be less than 359
MaxBandwidth. See Section 7.7.2 for more details. 360
