RE: Lost the rawdevice mapping

You should be able to recover easily from this, provided you haven't damaged your disks. The name of the rawdevices (and/or the mapping block device to raw device) is not important for ASM which keeps track of the necessary information within disk headers and other structures allocated in the disks themselves. So if you just make ALL the required storage visible to ASM in any order that should be good enough. BTW, you don't need to use rawdevices with 10.2 (on RHEL4 or higher), block devices are OK for ASM (tested).
PS: if are using RAC you would need to restore the OCR and voting disk rawdevices with the correct names though.
