Oracle : Ошибка ORA-15003


"diskgroup \"%s\" already mounted in another lock name space"
*Cause: The diskgroup could not be mounted by the ASM instance because
it was operating in a lockspace different than another existing
ASM instance which had already mounted the diskgroup.
*Action: Check the LOCK_NAME_SPACE initialization parameter value, or
dismount the diskgroup from the other ASM instances.
