Saving logical partitions and system applications

With logical partitions, you can distribute resources within a single system to make it function as if it were two or more independent systems. You can back up each logical partition separately, or as a set of connected systems.

System i® models support two types of logical partitions:
  • Integrated servers running on an IBM® i partition. An integrated server is a combination of integrated server hardware, network components, virtual disks, shared devices, and IBM i integrated server configuration objects.
  • System partitions on systems that use POWER5, POWER6® or POWER7® processors. You can install AIX®, Linux®, and IBM i operating systems on these systems.
    Attention: If you are using the Hardware Management Console (HMC), you must back up the HMC in addition to saving the individual logical partitions.

You can manage IBM i client logical partitions on an IBM BladeCenter blade server by using the Integrated Virtualization Manager.

The diagram shows the save commands that can be used for different file systems:

  • The root (/) file system is saved with SAV.
  • QSYS.LIB can be saved with SAVSYS, SAVCFG, SAVSECDTA, SAVLIB, SAVOBJ, SAVCHGOBJ, or SAV.
  • QDLS (Document library services) can be saved with SAVDLO, or SAV.
  • QOpenSys (Open systems) is saved with SAV.
  • Domino® server data directory is saved with SAV.
  • User-defined file systems (/dev/QASPxx/) or (/dev/asp-name/) are saved with SAV.
  • Other file systems, such as QNTC for Linux, are saved with SAV as well.
