So I am curious why this happens. It has happened to me before and again
now. I used to think it was all powerpath mess. But now it is happening
without powerpath on different levels of nw65 sp's.

1. Server has 2 Luns A and B with Powerpath installed.
2. Create 3rd Lun C.
3. Mirror Lun A and B to Lun C
4. When complete break mirror by removing partitions A and B
5. Remove A and B from SAn
6. reset server and 20min hang
7. remove powerpath.
8. reset server and still 20min hang!!
