ChrisDuk112,  This is likely due to an issue with the PCI risers, cards  or slots, What are the PCI cards you have currently installed, other than the SAS6 controller? Try removing all the cards, after reseating the risers, and then try booting. If same error then try swapping with known good risers, if you have any other 1950's with the same riser layout. If replacing the larger riser doesn't resolve the issue then it is likely an issue being caused by the motherboard. Let me know what you find.
HI one of our servers went down in the night.  I connected to its KVM and it shows after BMC on bios:  degraded link width error: embedded i/o bridge device 1expected link width is x4actual link width is x1  I've been to our data centre and brought the machine to back the office. I've tried replacing the smaller PCI-E riser which didnt help, I've ordered the larger PCI-E riser to see if swapping that out helps. I've too tried disconnecting the backplane and removing the SAS6 card but the error still comes up? Any pointers to help fix the issue?
