| |
Hello,
I just encountered a real bad problem with using media scan on 3ware controllers. I have 3 hds connected and configured a RAID5. I use media scan regularly (daily basis). Since two days I see this problem:
Nov 3 18:12:11 box 3w-xxxx[2039]: INFORMATION: Verify started on unit 0 on controller ID:2. (0x29) Nov 3 18:19:41 box kernel: 3w-xxxx: scsi2: Unit #0: Command (f6e5d800) timed out, resetting card.
After that the box has problems, the controller obviously hangs. This in itself can be considered a bug, but what is really annoying is that one has no chance finding out _which_ port caused the problem. So at this point you can play roulette and replace one of the hds hoping that it was indeed the bad one.
It would be really a lot better to degrade the unit in this case and give a hint which port has problems (command timed out on port ...). This would: a) not hang the box b) give you a chance to replace the hd, as you would expect in RAID5
The current situation is absolutely _no good_.
