The Emulex hbacmd(1m) utility can be used to print numerous configuration and performance attributes. The performance attributes can be used to gauage throughput and signal loss, which can aide in debugging performance and reliability issues. To view all available performance metrics, the hbacmd utility can be invoked with the “portstat” option and the WWPN to view:
$ hbacmd PortStat 10:00:00:00:c9:49:28:47
