Hi Iyyanar ,

Since you mentioned that Controller Firmware is latest. (Version:7.00 (9 Sep 2019)
Make sure you have te Latest Smart Storage Administrator installed 
> Please check the Status in Smart Storage Administrator If you are getting the option to Re-enable the Cache .

> If Battery status is Ok , possible issue is Cache Module itself .
> Since Battery is Ok ,if the problem persists, you need to replace the control card. because the cache module is embedded.

Hi,
Yes I have already tried to re-enabled the cache settings but problem remain so let me replace the controller card since cache memory is embedded and confirm you the final status soon..
