Your diagnostics could show what happened.

 

If the drive is OK, you will have to rebuild as parity2 is most probably not in sync anymore.

Have add a diagnostics after a reboot disk say the same

You are having issues with multiple disks:

 

Sep 18 00:53:05 Tower kernel: sd 10:0:2:0: Power-on or device reset occurred
Sep 18 00:53:05 Tower kernel: sd 10:0:8:0: Power-on or device reset occurred
Sep 18 00:53:08 Tower kernel: sd 10:0:2:0: Power-on or device reset occurred
Sep 18 00:53:08 Tower kernel: sd 10:0:8:0: Power-on or device reset occurred
Sep 18 00:53:08 Tower kernel: sd 10:0:16:0: Power-on or device reset occurred

 

This is usually a connection/power problem.

But when the disk use a backplate with 4 disk it sound wird  it not all 4 or do I miss something

Could be a backplane problem, or cable, or power, you can also update the LSI firmware.
