After creating RAID 5 for hard disks, CIMC shows Modrate fault

Dear all,

There are two UCS servers which the model is C240 M3


When I created RAID 5 for hard disks, CIMC shows Modrate fault.


The warring message is


storage virtual drive 0 degraded: please check the storage controller, or reseat the storage drive ucs


anybody has idea for this case? Thank you!

What is the RAID controller model? 9266-8i ?

Is this a Seagate drive? If it is check if the serial number is like the one below?

If the serial numbers are the same you will want to upgrade the firmware on these drives.

It will be a good idea to open a TAC case to take a look at the server...

Is it an solution? Thank you

Is it an solution? Thank you!

The warning message appears if you do not have a Battery BAckup Unit Instllated on the server. I just worked with Cisco TAC and following is the solution.:


1. Launch KVM Console of the server

2. Power Cycle the Server

3. When LSI RAID configuration window displays, press CTRL+H and start the RAID Configuration Utility.

4. Click on Virtual Drive. Example Virtual Drive 0.

5. Change Default Write Mode to "Write Through" and click "Change"

6. Press "Yes" to take the effect.

7. Exit from RAID Configuration Utility nad restart the server.
