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?
Solved! Go to Solution.

Re: vgexport/vgimport
Since 11.31 supports both legacy and persistant device files you do not have any issue to import the VG

Re: vgexport/vgimport
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.

Re: vgexport/vgimport
Are you able to see same disks on (11.31)
coresponding to (hpux 11.11) .?
<
Yes
vgexport -pvs -m
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
where mapfile is the one copied from the first node
If no error, remove the preview mode
>>>>vgimport -vs -m
