PowerPath & PVlink
Le nombre d'alternate PV est effectivement différent selon les VG. Ils sont utilisés lorsque PVlink est en charge du failover. Dans le cas de PowerPath, ils n'ont pas d'utilité car le driver PowerPath agit à une couche inférieur du LVM HP-UX. Quelquesoit le chemin utilisé par LVM, PowerPath redirigera les I/Os vers le chemin actif du disque. En clair, la définition d'alternate PV dans LVM n'est pas utilisé dans la gestion du failover par PowerPath.
