I,m extremely new into this world of AIX and pseries.
You both agree that pdisk15 had died, but physically on the pseries why do I see all disk with green light?, if one of them is death, it should show with ligth off or orange ligth?.
Sorry if my question sound extremely akward

I just want to know exactly what disk to replace.
