vgimport fail on hp-ux 11.31

[La_4]

i tried to vgimport -s -m mapfile vgname on the fail over node in cluster
after using vgexport -v -p -s -m mafile vgname

it give me error:
/etc/cmcluster/aafcexp$ xp-11082010.map vgaafcexp <
vgimport: Volume group "/dev/vgaafcexp" already exists in the "/etc/lvmtab" file.

any help would be appreciated.

If existing you need to export it before import.

so i have to do vgexport on the adoptive node (fail over node). what is the parameter to use. Please give details...

thanks

vgexport vgaafcexp
You then need to use the vgimport command. In 11.31 it shoul dcreate the directroy and group file automatically, but MAY not give it the name you want.
So I would then do:
mkdir /dev/vgaafcexp
mknod /dev/vgaafcexp/group c 64 0x??0000
Where ?? is the number as per the primary node.
Unless you are looking to use LVM2, in which case it is:

mknod /dev/vgaafcexp/group c 128 0x???000

the volume group is already exist on the adoptive node for fail over. I added more disks on the primary node so now i need to update the vg on the adoptive node with vgimport.

by doing vgimport vgname, it won't delete other volumes group on this node since this node has more then 10 packages up and running as well.

thanks

Hi,

>the volume group is already exist on the adoptive node for fail over. I added more disks on the primary node so now i need to update the vg on the adoptive node with vgimport.

The only way to update the VG with the newly added disks on the adoptive node is to export and re-import the vg with the mapfile taken on the primary node. So you should do a vgexport first on the adoptive (failover) node, and then a vgimport.

Don't be afraid, this won't affect the other packages. ;)

That's right that what i did.
- first i vgexport -v -p -s -m mapfile vgname
- second, copy mapfile to fail over node
- third, vgimport -s -m mapfile vgname
error:
/etc/cmcluster/ xp-11082010.map vgaafcexp <
vgimport: Volume group "/dev/vgaafcexp" already exists in the "/etc/lvmtab" file.

If existing you need to export the VG before import on the second node.

Hi La,

Torsten means that you should adapt your procedure

[from]

primary node

- first i vgexport -v -p -s -m mapfile vgname
- second, copy mapfile to fail over node

failover node

- third, vgimport -s -m mapfile vgname



[to]

primary node

- first i vgexport -v -p -s -m mapfile vgname

- second, copy mapfile to fail over node

failover node

- secondandahalf, vgexport -v vgname

- third, vgimport -s -m mapfile vgname

You forgot to execute, the "real" vgexport, on the failover node.

Greetz,
Chris
