[OmniOS-discuss] Parity error on path mpt_sas2

[Brogyányi József]

Some days ago I had same issue. My problem was very easy. Of course I 
already known it.
I had another problem too. The smartctl is show me the next error what 
is growing up and up.
199 UDMA_CRC_Error_Count
Anyway the solution is very easy. I have two PCIe slot and I tried the 
another slot and that's it.
Please write it back if it works for you. May be the FW downgrade is 
good idea.
ps
1 PCIe 1x16 (x16, PCIe 3.0)
2 PCIe  1x16 (x4, PCIe 2.0)
HBA FW is 20.
