Last week I updated the firmware on my M1015 to the latest version from LSI, P20.

 

All the drives attached to this card started giving lots of errors when I started a parity check.

 

Smartctl showed they all had UDMA_CRC_Error_Count errors.

 

I had to completely clear the card and then reflash to P19 as trying to go from P20 to P19 failed, now a parity check is showing up error free.

 

Does anybody know how to clear the UDMA_CRC_Error_Count value on the drive.

I doubt that you can.  You shouldn't be able to change smart error values, if just for the purpose of resale

 

What are the details of drives?

 

Before reflashing did you attempt to work the cabling for problems?

I've had no problems with drives in the 3 years the server has been running. CRC errors happened after the P20 update.

 

Went back to P19 and all is well again so I don't think it's anything to do with cabling.

 

Kevin.

9211-8i fw P20 rev. 20.00.02.00 should have solved that issue since what's reported on changelog.

 

I'm using it on Windows 7 environment on 2xSSD RAID0 with no issue at all. 

Just bought another M1015 and crossflashed to P20 v.20.00.02.00 IR mode to use with my desktop PC.

 

All fine as ever! 

Might be alright with Windows but while P19 works fine with unraid I'll stay on it.
