vgreduce(1M) vgreduce(1M)

vgimport command place too many links beyond the max limit allowed in the

lvmtab ﬁle. Currently the max limit is 8 paths to a PV (7 alternates and one pri-

mary). In this situation invoking the command without the

-f option will not

resolve the condition because the path is not attached to the volume group. Simi-

larly the condition would not be overcome by invoking with the

-f option as this

works on PVs rather than links.

pv_path The block device path name of a physical volume.

vg_name The path name of the volume group.

EXTERNAL INFLUENCES

Environment Variables

LANG determines the language in which messages are displayed.

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)).

EXAMPLES

Remove physical volume

/dev/dsk/c0t1d0

from volume group /dev/vg01:

vgreduce /dev/vg01 /dev/dsk/c0t1d0

Force reduction of missing PVs from volume group: vg01

vgreduce -f /dev/vg01

Removes the physical volume from the volume group when it is still in the lvmtab ﬁle, but it is currently

marked as missing from the volume group: vg01

vgreduce -l /dev/vg01

The following messages will appear after missing PVS has been removed successfully:

PV with key 0 successfully deleted from vg

/dev/vg01

Repair done, please do the following steps.....:

1. Save

/etc/lvmtab to another ﬁle.

2. Remove

/etc/lvmtab.

3. Use

vgscan -v to recreate /etc/lvmtab.

4. NOW use vgcfgbackup (1M) to save the LVM setup.
