vgexport

Patrick's method is the one that you should have used at the time of VG creation. If a SAN device presents itself with 8 paths, it is better for you if you add them all to your VG, so that if one or more goes bad, you should still have access to your disk.

There is no reason why this method should not work right now, provided you have at least some of these 8 channels to your LUN available and working. vgexport and vgimport commands are not the right fit for your problem's solution.

Hi,

Yes. it is possible. When the primary path is down, only thing is, you cannot activate the volume group. But still you can add alternate paths using vgextend.

You could have tried that.
