Your server probably has the 6402 raid controller amd if so the HP-UX OS would not see the replaced disk. Check with
ioscan -fn
and look for a /dev/cissX device(X can be 0,1,2,3...)

You control the disks within the 6402 controller using the saconfig and sautil commands. Search in this forum for "saconfig sautil" and you will find many examples on how to use them. Or check the man pages.
