Chapter 2. Core procedures

There are a number of core procedures that are used in multiple scenarios of the

accompanying chapters. These procedures are documented fully in this chapter

and additional notes are provided about the procedures that will not be found in

the fully worked-through examples in subsequent chapters. Some of the

additional notes are about issues such as best practices, and some are

additional diagnostic methods that may be used.

Some of the procedures in this book rely on being able to reconfigure a Virtual

I/O Server’s devices and mappings and the procedures could become complex if

many migrations resulting in many changes to the configuration occur. For this

reason, you may consider backing up the Virtual I/O Server configuration using

the Virtual I/O Server viosbr command, which creates compressed files from the

Virtual I/O Server configuration without having to perform a full Virtual I/O Server

backup. For further information, use the Virtual I/O Server man viosbr command

or refer to InfoCenter documentation.

The core procedures are:

򐂰 Using file-backed optical devices to perform a restoration

򐂰 Checking unique disk identification: IEEE, PVID, and UDID

򐂰 Creating a virtual SCSI device

򐂰 Using virtual Fibre Channel and NPIV

Each of these procedures is detailed in the sections that follow.
