The Virtual Partition Manager is a feature of i5/OS® that allows you to create and manage one i5/OS logical partition and up to four Linux® logical partitions on a single IBM® System i5® or eServer™ i5 server. You can use the Virtual Partition Manager to partition any IBM System i5 or eServer i5 model that does not require a Hardware Management Console (HMC), such as a model 595.
To use the Virtual Partition Manager, you must first install i5/OS on an nonpartitioned server. After you install i5/OS, you can initiate a console session on i5/OS and use System Service Tools (SST) to create and configure Linux logical partitions. i5/OS controls the resource allocations of the logical partitions on the server.

This figure illustrates the i5/OS logical partition and the Linux logical partitions that are managed by the i5/OS logical partition. The user creates and configures the Linux logical partitions on the server by accessing SST over the twinaxial console.
When you use the Virtual Partition Manager to partition an IBM System i5 or eServer i5 server, SST is the only tool that you can use to create and manage the logical partitions. You cannot use iSeries® Navigator to create or manage logical partitions on an IBM System i5 or eServer i5 server. However, the console session that you use to access SST can be initiated using either iSeries Operations Console (LAN or direct attach) or a twinaxial console.
