rpwwn
Displays the remote port’s PWWN.
Quality of Service statistics (HBAs only)
Use HCM and BCU to display quality of service (QoS) statistics for individual ports. You can display
statistics for fabric login (FLOGI) activity, exchange link parameter (ELP) activity, and received QOS
registered state change notifications (RSCNs).
Displaying QoS statistics through HCM
Use the QOS Statistics dialog box to display QoS statistics.
1. Launch the HCM.
2. Select the base adapter port from the device tree window.
3. Click Monitor > Remote Port Statistics > QOS Statistics.
Displaying QoS statistics through BCU
Use the qos --stats command to display remote port statistics.
vport --stats <port_id> vpwwn
where:
port_id
ID of the port for which you want to display rport statistics. This could be the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1 you
would use 1/1 as the port identification.
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 virtual port statistics through HCM
Display statistics by selecting Monitor > Statistics > Virtual Port Statistics.
OR
Right-click a virtual port on the device tree and select Virtual Port Statistics.
