Failed Raid 5

Hi,

I just got home from holidays... And when I tried to read my mails I
noticed a drive og my raid 5 was marked as faulty. When reconstructing it
another drive seemed to failed - but I think there was some trouble with
my SCSI controller and another drive was marked as faulty...

How can I try to recover the raid. The first and third disk should be
fine.

Here is my raidtab:

raiddev                 /dev/md3
raid-level              5
nr-raid-disks           3
chunk-size              128
persistent-superblock   1
parity-algorithm        left-symmetric
device                  /dev/sda6
raid-disk               0
device                  /dev/sdb6
raid-disk               1
device                  /dev/sdc6
raid-disk               2


when trying to make a raidstart /dev/md3, I get the following output in
/var/log/messages:

I hope somebody out there is able to help me :))
