If you reinstall the OS, you might need to install certain package updates before you put the server and optional hardware or software components into production. If you reinstall the OS, confirm your system is not impacted by S7-2L 12- and 24-Disk Backplane Systems Unable to Enumerate Disks (18712182).
Install the most recent Oracle Solaris 11.3 Support Repository Update (SRU). Taking this action ensures that your server has the latest software for the best performance, security, and stability.
Use the pkg info entire command to display which SRU is currently installed on your server.
Use the pkg command or the package manager GUI to download any available SRUs from https://pkg.oracle.com/solaris/support.
See "Installing the OS" in the server's installation guide.
