vgversion.1m (2010 09)

vgversion(1M) vgversion(1M)

• The migration of volume group version 1.0 to 2.0 or higher requires the kernel driver, which supports

volume group version 2.0 or higher, to be loaded.

• During migration of volume group version 1.0 to 2.0 or higher, all device special ﬁles associated with

the vg_name may get recreated. The applications need to take care of recreating the symlinks or

hardlinks to the new device special ﬁles of the volume group vg_name post successful migration.
