*Cause: An ALTER DISKGROUP ADD DISK command specified a disk that could
not be discovered by one or more nodes in a RAC cluster
configuration.
*Action: Determine which disks are causing the problem from the

for the device and the storage sub-system configuration on
each node in a RAC cluster that cannot identify the disk.
