When zoning hosts (actually HBA ports) to EMC Clariion SP ports, it is often beneficial to know which Clariion SP and port a WWPN is associated with. You can easily determine this by taking the Clariion WWPN (50:06:10:60:10:F3:84 in the following example) and breaking it down into three pieces: EMC identifier => 50:06:10 SP and [...]
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 [...]
