MD3000 with error codes and corruption of files.

Howdy all.
Got the following errors happening.

(this only effects slot 0)
Event type: 4011
Description: Volume not on preferred path due to AVT/RDAC failover
Component location: RAID Controller Module in slot 0

both : Component type: Enclosure Component (EMM, GBIC/SFP, Power Supply, or Fan)

Date/Time: 24/04/09 07:38:28
Event type: 1707
Description: Degraded wide port becomes failed
Component location: Enclosure 0, Slot 1

Date/Time: 24/04/09 07:38:22
Event type: 1706
Description: Optimal wide port becomes degraded
Component location: Enclosure 0, Slot 0

Both slots have the same errors around the same time.

Due to the enclosure not rebooting (as far as I know) does this
mean that one of the cables are loose?

I also saw this in the storage array profile:

CUMULATIVE ERROR COUNTS

RAID Controller Module 1

Sample period (hh:mm:ss): 00:00:00

Due to only having 2 hdds installed and seeing corruption (found.000 dir with .chk files in it) (Raid 0), Could this be a hdd issue?
