Hi,

If you have upgraded to STM 5.1, you can drill down on the Database or Logs LUN Target View and see what VM are driving load (if present) and see if other LUNs on the same Volume Group are loading up the disks.  It should tell you if you if the LUN is overloaded or if the Volume Group is overloaded.
