vgexport/vgimport

[RuudPeters]

Hello,

I have a server running with hp-ux 11.11. We intend to move the data which is on a san to a new server running hp-ux 11.31. Are there any known issues regarding to the vgexport on the 11.11 server and then the vgimport on the new server running 11.31 ?
Is it straight on ?
Regarding to the vgimport can I immediatly use the persistent device files on the 11.31 server?

Hi:

There are no issues with exporting and importing the volume groups nor should there be using the new persistent device files.

Regards!

Hi,

Since 11.31 supports both legacy and persistant device files you do not have any issue to import the VG

No.. no known issues.

Only issue while upgrading.

Satisfy yourself by looking at the below link

Dear Ruud

There is no issue, make map files and import in second server.

thanks and regards

The filesystem structure on the disks should be vxfs version 4 or 3.5 so it should successfully mount on 11.31.

LVM is compatible for vgimport and vxvm should be able to import a older disk group.

Are you able to see same disks on (11.31)
coresponding to (hpux 11.11) .?

Yes



vgexport -pvs -m /dev/vgxx

Copy the mapfile to the other node

Recreate the directory
>>>>mkdir -p /dev/vgxx

Recreate the VG group file
>>>mknod /dev/vgxx/group c 64 0xMM0000
where MM is a unique identifier (ex 01 for vg01)

Preview the vgimport to check for any possible error
>>>>vgimport -pvs -m /dev/vgxx
where mapfile is the one copied from the first node

If no error, remove the preview mode
>>>>vgimport -vs -m /dev/vgxx
