/usr/sbin/vgsync VolumeGroupName ...
This command is no longer supported on Digital UNIX systems. Features formerly provided by the Logical Volume Manager (LVM) are now provided by the Logical Storage Manager (LSM). Existing LVM volumes must be migrated to LSM, using an encapsulation process. For information about moving LVM volumes to LSM, see the vollvmencap(8) reference page and the manual Logical Storage Manager.
The vgsync command synchronizes the physical extents. The synchronization occurs on the physical extents that are stale mirrors of the original logical extent of the logical volume(s) belonging to the volume group(s) specified by the VolumeGroupName parameter. The synchronization process can be time consuming, depending on the hardware characteristics and the amount of data. Unless disabled, the mirrors within a volume group are synchronized automatically when the volume group is activated by the vgchange -a y command.
To synchronize the mirrors on volume group vg04, enter: vgsync /dev/vg04
