renatoyk — Sat, 16 Feb 2019 09:05:44 GMT

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.

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.

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 :-)

Can you give more detail on "Executed HP provision tasks to erase server and disks (this cleared cache);"? I looked widely and deeply for what it might be in the menus without success.
