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:

NAME

       lvdisplay - display attributes of a logical volume

SYNOPSIS

       lvdisplay [-c|--colon] [-d|--debug] [-h|-?|--help] [--ignorelockingfailure] [--maps] [-P|--partial] [-v|--verbose] LogicalVolumePath [Logi-
       calVolumePath...]

DESCRIPTION

       lvdisplay allows you to see the attributes of a logical volume like size, read/write status, snapshot information etc.

       lvs (8) is an alternative that provides the same information in the style of ps (1).  lvs is recommended over lvdisplay.

OPTIONS

       See lvm for common options.

       -c, --colon
	      Generate colon separated output for easier parsing in scripts or programs.  N.B. lvs (8) provides considerably more control over the
	      output.

	      The values are:

	      * logical volume name
	      * volume group name
	      * logical volume access
	      * logical volume status
	      * internal logical volume number
	      * open count of logical volume
	      * logical volume size in sectors
	      * current logical extents associated to logical volume
	      * allocated logical extents of logical volume
	      * allocation policy of logical volume
	      * read ahead sectors of logical volume
	      * major device number of logical volume
	      * minor device number of logical volume

       -m, --maps
	      Display the mapping of logical extents to physical volumes and physical extents.

Examples
       "lvdisplay  -v  /dev/vg00/lvol2"  shows attributes of that logical volume.  If snapshot logical volumes have been created for this original
       logical volume, this command shows a list of all snapshot logical volumes and their status (active or inactive) as well.

       "lvdisplay /dev/vg00/snapshot" shows the attributes of this snapshot logical volume and also which original logical volume it is associated
       with.
