Goal

A target reset is the result of retryable errors on a host, and is issued by the host to reset its target nexus or LUN. This indicates that after a SCSI packet was sent, a reset occured on the bus that prevented the completion of the packet. This may be an indication of a faulty component on the fibre channel path. Identifying the host bus adapter (HBA) involved is one essential step in troubleshooting the problem.

This document describes how to identify the HBA which initiated the target reset.
