sorry for the late reply,

The software on the machine is whithout the software from EMC. I know what you guys maybe thinking, but EMC assured me, it should work only using the QLA2300 software from my HBA. If i would install the EMC drivers next to the IBM (F20) drivers for the disks, my system would probably crash.

So i have no EMC software installed, and i can only see the emc disks on the LUN of my HBA.
