LVM Management
hi all,
Can you please advise on how to import or export the active volume group of devices from active to standby server ?
For HPUX, we should be using vgexport at active server , while by using vgimport at standby server
Regards

Re: LVM Management
Are you setting up a cluster (Serviceguard or similar)?
For Linux, vgexport/import is not needed.
1.) Present the LUN(s) to the standby server.
2.) Check that the devices are detected correctly (multipath etc.) on the standby server.
3.) Run "vgscan" on the standby server. You may wish to add one or two -v options for extra verbosity, so you can verify it does the right thing.
4.) You're done.
Like HP-UX, Linux tends to activate all available volume groups automatically at boot. In a cluster, you usually wish to limit that automatic activation - see the installation instructions of your cluster software.
In HP-UX, the device files for the LVs appear when the VG is imported. In Linux (2.6 kernel series = LVM2) this is different: the device files will appear automatically when the VG is activated, and will be auto-removed when deactivating the VG.

Re: LVM Management
You no need to vgexport & vgimport,
Check below Link
http://www.linux.org/docs/ldp/howto/LVM-HOWTO/recipemovevgtonewsys.html
Please keep in consideration for others, who share their "Knowledge & time" in suggestion for your problem
I hope you know how assign points ? and close thread if your satisfied with answers.

Problems are common to all, but attitude makes the difference
