Very quick observation :

You have total six Driver attached in your system.
I guess you have 2 Drive part of Raid-1 and 4 Driver part of Raid-10.

Out of those six Drive, one drive is detected as "1.5Gbps" (see below part in dmesg log)

	PHY[8].AttachedDevHandle: 0x0009
	PHY[8].LinkRate: 1.5Gbps (0x80)
	PHY[8].PhyStatus: NewTargetAdde

LSI IR does not support mix of mix of different link speed Drivers in a single Volume.
I am not sure if this is root cause of the issue, but definetly worth to try why that Particular drive is 
At 1.5 Gbps link ?

Can you try to see if it is cable which is causing link to 1.5 OR Drive itself has 1.5 Gbps max speed. ?
