this is not quite true but a good guide line:
soft errors are like CRC corrected errors.
hard errors can't be corrected and are very bad.
transport errors are a communication issue on the SCSI bus.
the technically correct version is very hard to understand and linked in the other reply :-)

NAME
emlxs - Emulex-Sun LightPulse Fibre Channel host bus adapter driver
SYNOPSIS
SUNW,emlxs
The emlxs host bus adapter driver is a Sun Fibre Channel transport layer-compliant nexus driver for the Emulex Light-Pulse family of Fibre
Channel adapters. These adapters support Fibre Channel SCSI and IP Protocols, FC-AL public loop profile, point-to-point fabric connection
and Fibre Channel service classes two and three.
The emlxs driver interfaces with the Sun Fibre Channel transport layer to support the standard functions provided by the SCSA interface. It
supports auto request sense and tagged queueing by default. The driver requires that all devices have unique hard addresses in private
loop configurations. Devices with conflicting hard addresses are not accessible.
