I think you have to use a special flag to force it

I downgraded firmware to P18 and there are no more errors today. It seems, that there is something bad with P20 firmware!

The errors were on all disks attached to the controller, but only on high read activity. Writes did not generate the errors. I downgraded the firmware to P18 (which is what we are using at work) and the errors went away. Has anyone had success with this controller and the P20 firmware?

No problem on other disks in different pool but on the same SAS cable. So maybe I only had bad luck with that disks.
