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.
