HP P600 1792-Drive Array Reports Valid Data Found in Array Accelerator

[Alex Bidu]

Running out of options with the P600 controller as we are unable to provide a stable data flow for our Linux server.
The array is mounted and works great but after some data exchange the drive does not exchange any data and I/O error during data read. The only temporary fix so far is to reboot the server but after "some" data exchange we again have the same problem.

I know this issue has something to to with the: Drive Write Cache...

Here is the configuration of the controller:

Hi,


Error Message: 1792-Drive Array Reports Valid Data Found in Array Accelerator...
...Data will automatically be written to drive array.

Cause: Audible Beeps: None Possible Cause:
Power was interrupted while data was in the array accelerator memory. Power was then restored within several days, and the data in the array accelerator was flushed to the drive array.

Action: No action is required. No data has been lost. Perform orderly system shutdowns to avoid leaving data in the array accelerator.

regards.

Thanks for the reply.
The array keeps on having the same issue eve tho the server and the disk pack is under UPS power. Tried to update the firmware but the issue still remains the same.

The drives keep on failing and the reboot seems to be the only fix for the moment but that only works for a couple of hours.
