[OmniOS-discuss] Parity error on path mpt_sas2

[Filip Marvan]

Thank you for your help Aaron! I downgraded firmware to P18 and there are no 
more errors today.

It seems, that there is something bad with P20 firmware!



You saved me a lot of time :)

I had this exact same problem recently when setting up a new home server... 
same controller, same firmware (P20). 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?

Hi Dan,

thanks for reply.
Yes, errors are on all 5 disks in the same RAIDZ pool. No problem on other
disks in different pool but on the same SAS cable.
So maybe I only had bad luck with that disks.
