Remote port statistics
Remote port statistics can help isolate end-to-end login problems. Use HCM and BCU to display
statistics for the following:
• Port login (PLOGI) activity
• Authentication and discovery (ADISC) activity
• Logout (LOGO) activity
• RCSNs received
• Process logins (PRLI) received
• Hardware abstraction layer (HAL) activity
• Remote port speed capability (RPSC)
As an example of using these statistics for troubleshooting, if the host cannot see the target, you
can verify that the remote port (rport) is reporting itself online by comparing the rport offline and
rport online statistics. The rport online counter should be one greater than the rport offline counter.
If not, clear the counters and retry connecting to the remote port. Verify the rport online and rport
offline statistics again.

Launch the Target Statistics dialog box using the following steps to display target statistics.
1. Launch the HCM.
2. Select the base adapter port from the device tree window.
3. Click Monitor > Statistics > Remote Port Statistics > Target Statistics.
