When installing Solaris10 on RH2285H V2, it prompts that the hard disk cannot be found

When installing Solaris10 on RH2285H V2, it prompts that the hard disk cannot be found. Specifically, during the installation process, enter the ID, time zone, and configure the network card. When the installation progress starts, a box appears about 4%: Hard disk not found. ! I tried to install Kylin again, also at the beginning of the installation (delete the previous partition and create a new partition), and then in the next step, an error was prompted, such as the hard disk could not be found! What is the reason for this?

Thanks
