NAMEpvmove — move allocated physical extents from one LVM physical volume to other physical volumes DESCRIPTIONThe 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 physical 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 physical volume has been repaired and is available to receive data. Optionspvmove recognizes the following options:
EXTERNAL INFLUENCESEnvironment VariablesLANG 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)). EXAMPLESMove physical extents from /dev/dsk/c1t0d0 to /dev/dsk/c2t0d0 and /dev/dsk/c3t0d0: pvmove /dev/dsk/c1t0d0 /dev/dsk/c2t0d0 /dev/dsk/c3t0d0 If physical volumes /dev/dsk/c2t0d0 and /dev/dsk/c3t0d0 are the only ones that belong to physical volume group PVG0, the same result can be achieved with the following command: pvmove /dev/dsk/c1t0d0 PVG0 Move only the physical extents for logical volume /dev/vg01/lvol2 that are currently on /dev/dsk/c1t0d0 to /dev/dsk/c2t0d0: pvmove -n /dev/vg01/lvol2 /dev/dsk/c1t0d0 /dev/dsk/c2t0d0 |
