hi,

if you replace the HBA, yor WWN adress is changed so you need to change zoning and on the storage change access for you new HBA.

HP OPEN-V is XP storage.

Start by looking at the hardware paths that appear as NO_HW.

Are they on the same HBA port? Same switch port? Same XP port?

This is the first step to see where the problem is.
