I have 2 issues.
Here's the first one.....
Controller ID: 0 Unexpected sense: PD = Port 0 - 3 x1:0:1-Recovered data with ECC - data rewritten, CDB = 0x28 0x00 0x25 0x4a 0xfb 0x80 0x00 0x00 0x80 0x00, Sense = 0xf0 0x00 0x01 0x25 0x4a 0xfb 0x86 0x0a 0x91 0x20 0x11 0x00 0x18 0x07 0x00 0x80 0x00 0x01

Getting a ton of these errors....

Is my controller going bad or is the disk in slot 0 going bad?

The second issue is, my RAID 5 set I created is with 7 drives then I added a hot spare so a total of 8 drives.
For some reason my hot spare is no longer showing. See above pic. However, in the right of the pic it shows SAS Address 7. It used to show up as the hot spare.

Things seem to be running fine but slow.

I think one of your drives are dying. The controller did its thing and set the hot spare as one of the drives, but your config may suffer until you get the faulty drive out of there. Try to see if you can locate the drive thats spewing those errors would be my first action.

That's what I don't get.
The initial RAID 5 set was the first 0-6 drives and the 7th drive I added later for hot spare and it was displayed as the hot spare.

Shouldn't drive 7 still be available/shown in the list?
According to the screenshot where the physical drives show in the raidset, drive 7 does not exist.

How does one determine which is the drive going bad from the error messages?
If I assume Port 0 is port 0 and the number 3 in the string "3x1:0:1" is disk 3 then disk 3 on port 0 is going bad BUT the controller does not sho it bad or going bad.

Yeah I think its one of your drives, or perhaps one of cables you are using might be bad as well. So I would try testing with another cable if you have one? Maybe move the drives around to see if you still get the same errors on the controller.

Also, if one of your drives failed, then depending on your OS, it may no longer show up in your drive status window. Thats why I beleive the hot spare kicked in already to save the config. I could be wrong, but I think thats why you still see the raid config intact, but no hot spare. But it doesnt mean the drive is dead just yet. As I mentioned before, it could be the cable. At this stage, you just have to tinker and try out some things until you discover the culprit. I can say for sure that for SAS drives, an unexpected sense error is either a drive is going bad or a cable is bad. Rarely is it the SAS card. But tinker my friend! Lets see what happens.
