The following script is designed to run on Solaris x86 or Redhat systems with LSI and Adaptec hardware controllers. It will check for degraded states of those controllers using mpt-status, arccon or raidctl depending on hardware vendor and OS. If a degraded state is found it will send an snmptrap to your snmptrap collector.
