Replacing H240ar controler by a P440ar on a existing server with logical drives

[renatoyk]

Hi there,
I'm trying to do acontroller upgrade on a DL360 Gen9 Server (H240ar controler by a P440ar) but when server starts, POST ERROR is shown:
1795-Slot 0 Drive Array - Write back Cache Configuration does not correspond to this drive array"

Running Smart Storage Administrator, I Cant do anything. Message: CACHE STATUS PROBLEM DETECTED, To prevent data loss, configuration changes are not allowed. Physical disks are even detected by SSA.

Am I doing something wrong?

Hi,

Good Day !!!

I would like to request you follow as below.

Cause

• Power was interrupted while data was in the cache.
• Data stored in the cache does not correspond to this drive array.

Action

Please follow as below action.

• Match the cache to the correct drive array.
• Run HPE SSA to clear the data in the cache.
• Update SA controller P440ar firmware with the latest.

Let me know if you have further query.

Thanks for answer SanjeevGoyal,

It is a brand new controller, so I wasn't able to match correct array. All SSA configuration buttons were disabled in order to prevent data loss, accordig to the screen.

I followed these steps in order to replace controller:

- Installed P440ar in a lab server with a spare disk; (same error was found in lab server);

- Executed HP provision tasks to erase server and disks (this cleared cache);

- Removed P440ar from lab server and installed to produciotn server;

- Updated firmware and OS drivers.

Now production server is up and running :-)
