Oracle Error Message
ORA-15058: disk ‘string’ belongs to an incompatible diskgroup
Reason for the Error
An attempt was made to ADD to a diskgroup a disk which was already part of another diskgroup. The other diskgroup was written by a more recent software release.
Solution
Check the path specifier for the disk. If it is certain that the disk is not in use by another diskgroup, the FORCE option may be used to override this check.
