vgimport(1M) vgimport(1M)

The designated primary and alternate link might not be the same as it was conﬁgured before.

Alternate links will be added to the importing volume group even if they might not be conﬁgured in

the volume group initially.

If the original primary path of a disks become an alternate path after the newly imported volume group

entry is created in

/etc/lvmtab, the order can be easily reverted by using

vgreduce to remove the

primary path and then use

vgextend to add the path back again.

If additional alternate paths were added to the newly imported volume group, use

vgreduce to reduce

any alternate paths that were added but they were not needed.

ADDITIONAL WARNINGS

Starting at 10.20, the

vgimport command is supporting additional EMC Symmetrix disk product func-

tionality (see vgchgid(1M)). The vgimport command will be enforcing a new rule such that the group of

disks to be imported must have the same EMC Symmetrix attributes. Clearly this checking only applies

if the disks involved in the operation are EMC Symmetrix. Should the command ﬁnd an incompatibility,

a message of the following type will be produced:

"Attempt to mix incompatible EMC Symmetrix disk types failed. Physical volume /dev/dsk/cxtxdx is

EMC BCV disk, but physical volume /dev/dsk/cxtxdx is a standard disk. Please consult the EMC

Symmetrix documentation, if applicable".

If duplicate VGIDs (volume group id) were found in different types of EMC Symmetrix disks during the

vgimport -s operation, the above error message will appear, and the command will fail. Please refer

to vgchgid(1M) on how to modify VGID on the EMC Symmetrix disk.

Note that EMC Symmetrix disks which do not have any of the additional attributes can still be mixed

with non-EMC disks in a single 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

Import the volume group

/dev/vg01 that is located on physical disks /dev/dsk/c0t1d0

and

/dev/dsk/c0t3d0:

vgimport -v /dev/vg01 /dev/dsk/c0t1d0 /dev/dsk/c0t3d0

Activate the volume group following a successful import:

vgchange -a y vg01

Import the volume group /dev/vg01 using the mapﬁle, /tmp/vg01.mymap. mymap was previously

speciﬁed by the vgexport command on another system. The volume group, /dev/vg01, is speciﬁed in

mymap and will be used by the importing system only:

vgimport -v -m /tmp/vg01.mapfile /dev/vg01 \

/dev/dsk/c0t5d0 /dev/dsk/c0t7d0

Import the volume group /dev/vg02 using the mapﬁle, /tmp/vg02.mymap. mymap was previously

speciﬁed by the vgexport command on another system. The volume group, /dev/vg02, is speciﬁed in

mymap and will be shared among the exporting system, this system, and other systems importing the

volume group as shared:

vgimport -v -s -m /tmp/vg02.mymap /dev/vg02

Import the volume group /dev/vg02 using the inﬁle, /tmp/vg02.infile. infile was previously

speciﬁed by the vgexport command on another system.

vgimport -v -f /tmp/vg02.infile /dev/vg02
