Hi Edwin,

Are you talking about nfs (Network File System) or LVM (logical volume manager), import a filesystem or a volume group ?

Are you wanting to export an entire VG from one HP-UX system and import on another? If so, have a look at the vgexport and vgimport man pages. Those will do the trick for you.

If you are looking for something else, please elaborate.

There are the vgexport/vgimport commands.
Restoring from backup.
The pvmove command.

What is it you are trying to accomplish?
Are you moving disks around?
Just moving the data from 1 server to another?

Thnks for ur help.

I want to import all the volume groups en file systems in one server HP9000 to other. i want to lost my data... is that possible?

[Steven E. Protter]

For many files i'd recommend scp or sftp.

If both machines have a path to he disk, you can vgexport on one machine deactivate the volume group and vgimport on the second machine.

No data would be lost.

A lot however depends on your current configuration. You will need to bring down apps and databases that are using the data.

What steps have you taken? Without knowing what you have done so far, it's really hard to diagnose your problem.

i do this steps:

1. umount FS
2. Vgchange VG's
3. Vgimport VG's
4. vgchange VG's
5. mount /FS

thanks

You should have done a vgexport -p -m

Hi,

If both system have acces to the system then follow this.
In systemA
1) Umount all FS,
2) vgchange -a n
3) vgexport -m /tmp/map.file
4) rcp /tmp/map.file systemB:/tmp (or ftp)
In systemB
5) create vg folder and group file
(Refer to LVM guide)
6) vgimport -m /tmp/map.file
7) vgchange -a y
8) Create mount points and try mounting.

If only one system can access the disk, after exportingVG you need to move the disk aswell to another system. Make sure your disk is compatible, in terms of interface, SCSI -id...etc.
