Hi,

I have VxVm 3.1 configuration in one machine. I need to migrate the data
(on the SAN LUNs)
to the new hardware on which installed VxVM 4.0.

On the old machine, I have done the following:

1. stop all activity by applications. Unmount file systems.
2. vxvol -g alcateldg stopall
3. vxdg deport alcateldg

I have installed the new machine. After installation of VxVM 4.0,

I have run the following:

1. vxdg import alcateldg
2. vxrecover -g alcateldg -sb

The old machine's hostname is uranus. The new machine's name is titan.

I get the following.

# vxdg list
NAME STATE ID
rootdg enabled 1087675539.17.titan
alcateldg enabled 1087658143.1113.uranus
#

The first questions is that, why the disk group id is still pointed to
the old macihe's hostname although
I do the work according to the procedure (I think i use the correct
procedure ???).
To clear old disk grouo ID, I have run the (vxdg -C import alcateldg).
However,
anything is not changed.

Actually, I have mounted the LUNS and I have accessed the data in them.

# df -k

The strange thing to me, the vxprint -Aht command output.
There are some extra volumes, such as,

v alcvol03-L01 - ENABLED ACTIVE 1048576 SELECT
- fsgen

The full output of the vxprint -Aht command output is the following:

After the importing the disk group, I have also upgredade the disk group
version with
the following command: vxdg upgrade alcateldg ...

Why are alcvol03-L01 and alcvol03-L02 there? Is there anything wrong?
What are the purpose of these volumes?

Best regards,

Asiye Yigit
