Before you begin to install the Solaris OS, certain tasks must be completed. Choose the following tasks, depending on whether an OS is already installed on the server's drive, or if the drives are new and have no previous partitions.
If your server's boot hard disk has an operating system installed other than Solaris, you might need to erase it in order to prepare it for Solaris. See How to Erase Your Boot Hard Disk.
If your server did not come with preinstalled Solaris, you must create a logical drive using the server HBA software. If you do not, the Solaris installation program can not see the server's disk drives. See Creating a Virtual Disk.
If you are going to install your OS on a disk that is part of a RAID array, you must configure the RAID array before installing your OS. For details, see Creating a Virtual Disk and your server's disk management documentation collection.
