I have set up two oracle databases servers on vmware. I have mounted several luns from storage as shared disks so that I can use ASM technology to install oracle clusterware.

I made a mistake in the begining. I didn't put the fist disk on the storage instead I put them on the servers' local disks.

Today, when I tried to vmotion the first disk from the local disk to the LUN, I got the following error:

Virtual machine is configured to use a device that prevents the opeartion: device 'SCSI controller 1' is a SCSI controller engaged in bus-sharing.

You need to shut down oracle, do image copy of directly mapped LUN to VMDK disk of same size, and reassign it to EXACT port where LUN was assignes.
