Click Monitor > Statistics > vNIC Statistics. The vNIC Statistics for Eth Port dialog box displays. Displaying statistics through BCU Use the vnic--stats command to display remote port statistics. vnic --stats where: pcifn PCI function number associated with the vNIC. Virtual port statistics Use HCM and BCU to display logical port statistics for fabric discovery (FDISC) activity, logouts (LOGO) activity, NPIV support, number of fabrics online and offline, and fabric cleanups. Use these statistics to isolate NPIV login problems. Following are examples of what to check if virtual devices are not listed in the name server: • If FDISC sent and FDISC accept statistics do not match, the fabric or switch may not be ready for data transmission. This is normal as long as it does not persist. If it does persist, there may be a problem in the fabric or a protocol issue between the adapter and fabric. Note that in this case FDISC retries also increase. • Check the No NPIV support statistics to verify that NPIV is supported and enabled on the switch.

Displaying statistics through HCM
To display statistics, perform the following steps:
1.
Launch the HCM.
2.
Select an FC or FCoE port from the device tree
3.
Click
Monitor > Statistics > vNIC Statistics
.
The
vNIC Statistics for Eth Port
dialog box displays.
Displaying statistics through BCU
Use the
vnic--stats
command to display remote port statistics.
vnic --stats <pcifn>
where:
pcifn
PCI function number associated with the vNIC.
Virtual port statistics
Use HCM and BCU to display logical port statistics for fabric discovery (FDISC) activity, logouts
(LOGO) activity, NPIV support, number of fabrics online and offline, and fabric cleanups.
Use these statistics to isolate NPIV login problems. Following are examples of what to check if
virtual devices are not listed in the name server:
•
If FDISC sent and FDISC accept statistics do not match, the fabric or switch may not be ready
for data transmission. This is normal as long as it does not persist. If it does persist, there may
be a problem in the fabric or a protocol issue between the adapter and fabric. Note that in this
case FDISC retries also increase.
•
Check the No NPIV support statistics to verify that NPIV is supported and enabled on the
switch.
