The TaskGuide uses a graphical interface to guide you through the steps of
adding nodes to an existing volume group. For more information on the
TaskGuide, see 3.4.6, “Alternate Method - TaskGuide” on page 90.
Importing the volume group onto the destination nodes synchronizes the
ODM definition of the volume group on each node on which it is imported.
You can use the
smit importvg fastpath to import the volume group.
