You can use the importvg and exportvg commands
to move a user-defined volume group from one system to another.
Consider the following when importing and exporting volume groups
and logical volume storage pools:
- The import procedure introduces the volume group to its new system.
- You can use the importvg command to reintroduce a volume
group or logical volume storage pool to the system that it had been previously
associated with and had been exported from.
- The importvg command changes the name of an imported
logical volume if a logical volume of that name already exists on the new
system. If the importvg command must rename a logical volume,
it prints an error message to standard error.
- The export procedure removes the definition of a volume group from a system.
- You can use the importvg and exportvg commands
to add a physical volume that contains data to a volume group by putting the
disk to be added in its own volume group.
- The rootvg volume group cannot be exported or imported.
