We did P2V all redhat 5.5 physical server to virtual.
Here is the situation we ran into.After we P2V’d the servers, and moved all of their data to virtual drives, when I went to remove the RDMs from one server as a test, it actually rearranged all of the drives within the operating system after a reboot and oracle services won't start. We were able recover from it but I would like some help in understanding what caused the issue and how we can move forward with the remaining servers while avoiding the same thing. Customer using Oracle ASM.

Thanks
