vgsync(1M)							    vgsync(1M)

NAME
       vgsync - synchronize stale logical volume mirrors in LVM volume groups

SYNOPSIS
       vg_name ...

   Remarks
       This command requires the installation of the optional HP MirrorDisk/UX
       software, which is not included in the standard HP-UX operating system.

       If the volume group input arguments belong to a combination  of	volume
       groups  version	1.0  and  2.0 or higher, the arguments may not be pro‐
       cessed in the order they are listed on the command line.

DESCRIPTION
       The command synchronizes the physical extents of each mirrored  logical
       volume  in the volume group specified by vg_name	 ....  Synchronization
       occurs only on the physical extents that are stale mirrors of the orig‐
       inal logical extent.

       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 command.

   Arguments
       recognizes the following argument:

	      vg_name	     The path name of a volume group.

EXTERNAL INFLUENCES
   Environment Variables
       determines the language in which messages are displayed.

       If any internationalization variable contains an invalid	 setting,  all
       internationalization variables default to "C" (see environ(5)).

EXAMPLES
       Synchronize the mirrors on volume group

WARNINGS
       It is not advisable to interrupt a process.
