NAME
pvmove - move allocated physical extents from one LVM physical volume to other physical volumes
SYNOPSIS
/usr/sbin/pvmove [-A autobackup][-n lv_path] source_pv_path
[dest_pv_path ... dest_pvg_name ...]
Remarks
pvmove cannot be performed if the volume group is activated in shared mode.
DESCRIPTION
The pvmove command moves allocated physical extents and the data they contain from a source physical
volume, source_pv_path, to one or more other physical volumes in the same volume group.
If a destination physical volume or physical volume group is not specified, all physical volumes in the
volume group are available as destination volumes for the transfer. pvmove selects the proper physical
volumes to be used in order to preserve the allocation policies of the logical volume involved.
To limit the transfer to specific physical volumes, specify the name of each physical volume directly with a
dest_pv_path argument. Optionally, if physical volume groups are defined for the volume group, specify
the physical volumes indirectly with one or more dest_pvg_name arguments.
source_pv_path must not appear as a dest_pv_path.
If source_pv_path is a member of a dest_pv_path, it is automatically excluded from being a destination phy-
sical volume.
pvmove succeeds only if there is enough space on the destination physical volumes to hold all the allocated
extents of the source physical volume.
If you have installed HP MirrorDisk/UX on your system and source_pv_path is an "active spare" physical
volume within a mirrored logical volume, once all of the data has been moved to dest_pv_path, the
source_pv_path physical volume will be returned to a "stand-by" spare physical volume. This is how to
"unspare" data once the original failed physicalvolume has been repaired and is available to receive data.
Options
pvmove recognizes the following options:
dest_pv_path The block device path name of a physical volume. It cannot be the source physi-
cal volume. It must be in the same volume group as source_pv_path.
dest_pvg_name The name of a physical volume group. It must be in the same volume group as
source_pv_path.
source_pv_path The block device path name of a physical volume.
-A autobackup Set automatic backup for this invocation of this command. autobackup can have
one of the following values:
y Automatically back up configuration changes made to the physical
volume. This is the default.
After this command executes, the vgcfgbackup command (see
vgcfgbackup(1M)) is executed for the volume group to which the phy-
sical volume belongs.
n Do not back up configuration changes this time.
-n lv_path Move only the physical extents allocated to the logical volume specified by
lv_path that are located on the source physical volume specified by
source_pv_path.
EXTERNAL INFLUENCES
Environment Variables
LANG determines the language in which messages are displayed.
If LANG 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)).
