lvsync — synchronize stale mirrors in LVM logical volumes


/usr/sbin/lvsync lv_path ...


This command requires the installation of the optional HP MirrorDisk/UX software (not included in the standard HP-UX operating system) before it can be used.


The lvsync command synchronizes the physical extents of each logical volume specified by lv_path. Synchronization occurs only on physical extents that are stale mirrors of the original logical extent. The synchronization process can be time consuming, depending on the hardware characteristics and the amount of data.


lvsync recognizes the following argument:


The block device path name of a mirrored logical volume.

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