Re: ioscan gives NO_HW error !!!

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.

Re: ioscan gives NO_HW error !!!

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.
