The IBM eServer System p and IBM eServer System i systems introduce many options for partitioning, virtual or native devices, and consoles. Both versions of the system use the same kernel and have many of the same options available, depending on the system configuration.
If you are using a non-partitioned System p system, you do not need any pre-installation setup. For systems using the HVSI serial console, hook up your console to the T2 serial port.
If using a partitioned system, whether IBM System p or IBM System i the steps to create the partition and start the installation are largely the same. You should create the partition at the HMC and assign some CPU and memory resources, as well as SCSI and Ethernet resources, which can be either virtual or native. The HMC create partition wizard steps you through the creation.
If you are using virtual SCSI resources, rather than native SCSI, you must configure a 'link' to the virtual SCSI serving partition, and then configure the virtual SCSI serving partition itself. You create a 'link' between the virtual SCSI client and server slots using the HMC. You can configure a virtual SCSI server on either AIX or i5/OS, depending on which model and options you have.
Once you have your system configured, you need to Activate from the HMC or power it on. Depending on what type of install you are doing, you may need to configure SMS to correctly boot the system into the installation program.
