384 Logical Partitions on System i5
13.4 Preparing your system for Virtual Partition Manager
This section provides step-by-step instructions on how you can remove logical resources
from i5/OS using the Virtual Partition Manager, in preparation for defining new Linux
partitions. With your new eServer i5 system, by default, the i5/OS partition currently owns all
of the processor, memory, and I/O resources.
You can invoke the Virtual Partition Manager either through Dedicated Service Tools (DST)
or System Service Tools (SST) tasks. The advantage of using SST is that you can bring your
eServer i5 system to full operational mode rather than having to do your partition definitions in
a restricted state where the rest of the operating system has not started, and users are not
able to use the system.
We recommend that you manage your Linux partition, creation, and management through
SST tasks, which enables you to use your i5/OS environment concurrently. After you define
the partitions, a system IPL is required to complete the removal of resources from i5/OS.
13.4.1 Removing resources from i5/OS
1. .From the Main menu or i5/OS command line, start the System Service tools by typing
STRSST, as seen in Figure 13-2.
