Redefines the set of physical volumes of the given volume group in the device configuration database.
During normal operations the device configuration database remains consistent with the Logical Volume Manager (LVM) information in the reserved area on the physical volumes. If inconsistencies occur between the device configuration database and the LVM, the redefinevg command determines which physical volumes belong to the specified volume group and re-enters this information in the device configuration database. The redefinevg command checks for inconsistencies by reading the reserved areas of all the configured physical volumes attached to the system.
Note: To use this command, you must either have root user authority or be a member of the system group.
