vgreduce(1M) vgreduce(1M)

option was mainly designed for the problem where the

vgscan or the 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 (seven alternates and one primary). 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. Similarly, this condition can

not be overcome by invoking with the

-f

option, as the same works on physical

volumes rather than the 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.

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)).

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

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 to save the LVM setup.

Remove the physical volume /dev/dsk/c0t2d0

from the vg01 volume group when the physical

volume is still in the

lvmtab ﬁle but is currently marked as missing from the volume group:

vgreduce -l /dev/vg01 /dev/dsk/c0t2d0
