La création d’un Volume logique doit se faire avec les menus PowerHA pour être synchroniser  directement avec le nœud secondaire.

L’accès au menu de gestion des volumes logiques est décrit ci-dessous :

   System Management

     Storage                                                           

       Logical Volumes                                          

         List All Logical Volumes by Volume Group               

         Add a Logical Volume                                   

-          Sélectionner tout d’abord le VG de contenance de ce LV.

-          Donner le nom des nœuds devant être synchronisés( ou Auto-Select)

# Reference node        Physical Volume Name 

  Auto-select                                 

  avqprd1               hdisk5               

  avqprd1               hdisk9               

-          Remplir les champs minimum :
