Replacing smart storage battery on DL380 Gen 9 Erase RAID?

[lizmcc93]

I have been on support with HPE mulitple times due to an error in my ILO for my DL380:

Controller on Slot 3

    Model Smart Array P840 Controller Firmware Version 4.52 Controller Type HPE Smart Array Cache Module Status

 Failed

They have sent me out two different smart array cards to replace my current on with. After the first replacement the server did not power on at all, all LED lights flashed continuously. The second smart array card they sent me gives the same error as above. They now have sent me out a smart array battery to try chaning out. I have read most online that changing out the smart array battery will not erase the RAID configuration. I am wondering if this is true and if anyone else has had similiar experience like this? Was replacing the battery successful and your RAID stayed intact?

Thank you!!

Hello There, 

Smart Storage battery repalcement does not cause any data loss etc. However its always recommended to have data backup before performing any task on system to avoid any unease situations.

The array information is not stored on the controller.. The array information is stored in what is known as the RIS area on each disk in the array(s)
