"ERROR disk not found" during boot cdrom installation

Question

We were booting a T4-4 server from a Solaris 10 boot ISO and command I used was "boot rcdrom - install as nowin" (i was mounting the ISO using the serial redirection window etc, hence the rcdrom)
It worked great asking for the" language to be installed" and "network setting and etc."
then it starts communicating with the jump server to pick up the jumpstart script and etc still working great. but when it start to install, it returned with "ERROR no disk found"
I am sure there are two 600G disk on the server. not sure why it think there is no disk during the installation. googled it and some said something related to raid and i cannot get a conclusion.
