Hi Nappy:

To promote a alternate (secondary) pvlink to a primary, 'vgreduce' the current _primary_ path. This promotes the secondary to a primary. Now add back the original primary path. It will now be a secondary pvlink.

Using this method makes the relationships permanent. It is the order of appearance in the '/etc/lvmtab' that determines which path is primary and which is secondary. The primary is simply first therein.

Regards!
