Colin, Similar situation. 3rd party vendor enterprise level disk hardware. Sharing the spindles between z/OS and Oracle on *nix. Everything was happy until one day the mainframe performance hit a wall. Disk vendor blamed everybody else until I got some RMF reports that showed response time went from 1-2 milliseconds to over 500 per I/O. I finally got a physical drive mapping from them and discovered it was sibling pend between Oracle doing some kind of database copy that the back end disk hardware did within itself and that was killing anything else trying to use those physical disks. They couldn't get it fixed so they ended up providing us additional spindles so we could move the mainframe LUNs to separate hardware - on their dime.

They found they needed more x86 capacity than they planned for, and then had 3 vendors to worry about. I got involved in a performance problem and could see about 10% of the I/Os were taking over 500 ms. Each vendor pointed to another vendor as the problem. I think it cost them lots of money in fines because they did not meet the performance targets. I don't think they solved the performance problem - they re-architected to fix it.
