Storage System has disabled write cache

Hello team,

There has been many discussions on the mentioned error but this is a different case.

I am getting the alarm in EMC GUI "The Storage System has disabled write cache", when I checked from the V$ASM_DISKS tables I see only disk group OCR is being in closed state. As it is a standalone system so ocr is not required neither used b ut the system is designed to keep it for future expansions.

Just want to know if there is any impact of these errors in the system? performance etc.
