fcp

02/11/2024 Contributors

An FCP target port is a hardware endpoint that performs data communications over a physical link using the Fibre Channel Protocol (FCP). This table collects diagnostic and performance information for an FCP target port. The table counters can be used to diagnose link and connectivity issues on the port. These table counters also provide an overview of the ports IO performance. The alias name for fcp:node is fcp_node.
