Probably.

I would still back it up before moving anything around.

vgexport

save the vg configutation.

Make your physical move.

vgimport

Thats the possible outline I'd use.

I generally don't do things like that. I shut down the active databases, take a good fbackup, then move the disk around, redo the volume groups and restore.

It takes longer, but there are more ways to bail out.

Hi,

Yes it's possible with vgexport and vgimport.

I would prefer having backup before doing this operation
