mfi troubles (Unexpected Sense)

[Dmitry Morozovsky]

Colleagues,

one of my servers start to expose unexpected delays possibly related to disk 
subsystems.

It's Supemicro with mfi, ZFS on set of RAID0 (yes, I know we've missed the 
right controller, but this is out of question at least for the current time)

Now kernel log is filled with messages like

mfi0: 60006 (585001405s/0x0002/info) - Unexpected sense: PD 0e(e0x08/s5) Path 
500304800021bf31, CDB: 8f 00 00 00 00 00 14 77 5c 1e 00 00 10 00 00 00, Sense: 
3/11/00

every few seconds

I tried to find the place in the source which produce these lines but failed :(

Hard reboot, including full power off, was tried, but did not help.

Any hints to diagnose this further?

Ah, and this is stable/10 from Nov 2017


please keep me CC:d as I'm not subscribed to -scsi@

Thanks!
