When I was installing SQL cluster service I chosed a wrong qourom disk for SQL service (Disk2)
after i installed SQL cluster service on my both nodes, i wanted to change the qourom disk from (Disk2) to (Disk5)
I thought it was easy, and here is what I have done:
I added a new disk to SQL service (Disk5), and I removed the old disk (Disk2)..
now when I brows from SQL management studio to attach my DB it directs me to (Disk2), which is not available on this cluster server anymore.
If you need attachments please let me know, i am preparing it now.
