Switched on smartmontools.
```
smartctl -a /dev/sdf -d megaraid,0
```
shows no errors.
```

Download megacli from

```
megacli -LDInfo -L5 -a0

So the drives are OK and the controller is not complaining.
Smartctl self tests do not work on this controller:
```
tux04:/$ smartctl -t short -d megaraid,0 /dev/sdf -c
Short Background Self Test has begun
Use smartctl -X to abort test
```
and nothing ;). Megacli is actually the tool to use
```
megacli -AdpAllInfo -aAll
```
