lvsync(1M) lvsync(1M) NAME
lvsync - synchronize stale mirrors in LVM logical volumes SYNOPSIS
lv_path ... Remarks 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. If the logical volume 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 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 char- acteristics and the amount of data. Arguments recognizes the following argument: lv_path The block device path name of a mirrored logical volume. Options recognizes the following option: Perform mirror synchronization of logical volumes within a volume group using multiple parallel threads. Logical volumes belonging to different volume groups will be synchronized serially. It is possible that logical volumes start and/or complete their synchronization in a different order than specified on the command line. The maximum number of threads used can be controlled using the system tunable. NOTE: This option has no effect if the volume group is activated in shared mode. EXTERNAL INFLUENCES
Environment Variables determines the language in which messages are displayed. If is not specified or is null, it defaults to "C" (see lang(5)). If any internationalization variable contains an invalid setting, all internationalization variables default to "C" (see environ(5)). EXAMPLES
Synchronize the mirrors on a logical volume: Synchronize the mirrors on three logical volumes using multiple parallel threads: Add mirror copies using with the option for three logical volumes, and then synchronize mirrors on these three logical volumes using multi- ple parallel threads. First, add mirror copies to each logical volume using with the option: Now synchronize the mirrors on these three logical volumes using multiple parallel threads: SEE ALSO
