ORA-15040

diskgroup is incomplete

Cause

Some of the disks comprising a diskgroup were not present.


Action

Check the hardware to ensure that all disks are functional. Also check that the setting of the ASM_DISKSTRING initialization parameter has not changed. Alternatively, for normal or high redundancy diskgroups, use MOUNT FORCE to offline missing disks as part of mounting the diskgroup.
