Hardening Solaris Drivers
Fault Management Architecture (FMA) I/O Fault Services enable driver developers to integrate fault
management capabilities into I/O device drivers. The Solaris I/O fault services framework defines a
set of interfaces that enable all drivers to coordinate and perform basic error
handling tasks and activities. The Solaris FMA as a whole provides for error
handling and fault diagnosis, in addition to response and recovery. FMA is a
component of Sun's Predictive Self-Healing strategy.
A driver is considered hardened when it uses the defensive programming practices described
in this document in addition to the I/O fault services framework for error
handling and diagnosis. The driver hardening test harness tests that the I/O fault
services and defensive programming requirements have been correctly fulfilled.
