What part of the log shows that so I can look if it happens again?

 

These repeating errors:

Sep  9 11:39:15 Tower kernel: sd 11:0:2:0: Power-on or device reset occurred

You can see which disk it is by looking at lsscsi on the diags:

 

[11:0:3:0]   disk    SEAGATE  ST6000NM0285     EF04  /dev/sdm   /dev/sg12
  state=running queue_depth=254 scsi_level=7 type=0 device_blocked=2 timeout=30
  dir: /sys/bus/scsi/devices/11:0:3:0  [/sys/devices/pci0000:00/0000:00:03.2/0000:0c:00.0/host11/port-11:3/end_device-11:3/target11:0:3/11:0:3:0]

 

sdm is currently Disk4

I have (had) 2 parity drives and 6 data drives. All 14 TB drives. Parity Disk 1 had a lot of errors and it got disabled. I did a parity check with the 1 remaining drive and all came out well. Tried to add the parity drive 1 (bad one) back into array and it said it would take 54 days to sync. All drives are about a month old. This is a 24 bay supermicor server. I moved the bad parity drive to a different drive bay just in case. No effect.

This error repeating for multiple devices, this is most often a connection/power problem, you should also update the LSI firmware since it's quite old.
