vgimport -m filename

[blacof]

Can folks here tell me as to what is the
format of the file that is to be used for
importing a diskgroup with the -m option .

Im getting this error when I run vgimport

vgimport -m /tmp/mapRtRYWR -f /tmp/pathEMbuhC /dev/changehv

Physical volume "/dev/dsk/c5t0d6" has an unsupported LV
M disk layout.

I don't know that the format is readily available. The map file is supposed to be produced by the vgexport command. Did you do something else to it?

Can you give more information? Your LVM version? OS version?

Are you trying to import LVM2.0/2.1 VG to hp-ux 11.23/earlier 11.31?

Export the Volume Group /dev/vg01 into mapfile vg01.mapfile:
#vgexport -m vg01.mapfile /dev/vg01


Import the Volume Group /dev/vg01 from mapfile vg01.mapfile:
#vgimport -m vg01.mapfile /dev/vg01

Check in /etc/lvmconf/ for the mapfile if you not exported.

Hi:

The mapfile (designated with the '-m' argument) is simply a list of the logical volumes and their minor numbers. It will look like:

1 lvolX
2 lvolY
...

The '-f infile' points to a file of physical paths for the volume group. Make sure only one path per line occurs.

All this said, you haven't specified the *volume group* name. You should have something like:

# vgimport -m /tmp/mapRtRYWR /dev/vg01 -f /tmp/pathEMbuhC

...where '/dev/vg01' may be what you meant for '/dev/changehv'.

Regards!

Im using a 2.1 VG. Does the command line order matter I have specified /dev/changehv as the name of my vg.

[Turgay Cavdar]

LVM 2.1 is supported with release September 2008 of hp-ux 11iv3. You cannot import v2.1 VGs before September 2008 release of 11.31.

Hi (again):

> Im using a 2.1 VG. Does the command line order matter I have specified /dev/changehv as the name of my vg.

No, your command was correct and I was wrong. The manpages do show:

# vgimport [-m mapfile] [-p] [-v] [-f infile] vg_name

I think turgay may be correct. What's your operating system (OS) release and from where (what OS) does the physical disk come?

Regards!

Im using Sep 09 . Does the hvname and vg name have to be the same while importing as it was when it was exported ?

[Pete Randall]

No, the names may be different, but you have to create the group file:

mkdir /dev/vgNN
mknod /dev/vgNN/group c64 0xNN0000

then vgimport.
