Below is the error being repeated on my Solaris 9 Sun-Fire-V890 machine.
SAN team confirmed as everything is fine from their end. I did google and found that some people say its a known Oracle bug when you have Oracle 10G installed on your system but I kind of disagree with them. Please see below error and advice troubleshooting for the issue :
