Hi Marcio:

Have a look at the 'vgexport' and 'vgimport' manpages. They have some good examples to guide you. You can edit the device file paths in the "infile" prior to using 'vgimport' to match that of the receiving server. The mapfile is for associating the *logical volume* names to logical volume numbers, although by default, 1=lvol1; 2=lvol2, etc.

Hi Márcio

ServerA
vgchange -a n /dev/vg01
vgexport -p -s -m /tmp/vg01map /dev/vg01
copy the map file from A to B

ServerB
mkdir /dev/vg01
mknod /dev/vg01/group c 64 0x010000
vgimport -s -m /tmp/vg01map /dev/vg01
vgchange -a y /dev/vg01

The procedure given by Robert is correct,
and one more thing, Keep the minor number of the VG as used in server A. This will avoid other complications....

Hello,

I'm not going to export from one server to another. What i want to do is:

I have a server with a disk from EVA4000 presented, and i'm going to present a new disk from a EVA6000 to the same server, and i want to export the VG01 to this new disk (that is in the same server).

Thank you

Márcio

[Torsten.]

Do you mean by "export" you want to move data from the eva4k vdisk to the eva6k and use this as vg01?

2 possibilities (out of some more):

1) backup data, adjust config and restore data

2) mirror the data from 4k to 6k. Once this is done, remove the mirror from the 4k

[MárcioAFM]

Ok,

The data will be replicated using continuous access, in the server i need to put in the new disk the VG01 structure.

Thanks,

Márcio

So vgexport the vg (eva4k) after replication and vgimport the vg from eva6k.
