raid 5 Interim recovery (volume functional, but not fault tolerant)

[Maleas Nikoloas]

I have an ML110G5 with 3 HD on raid 5 , and E200 RAID controller.
I got a message"
The following disk drive need Automatic Data Recovery (Rebuild): Port 1I: Box 0: Bay 4
Automatic Data Recovery previously aborted."

I try Automatic data recovery. The system started rebuilding and i had the following Status:

_______Time "0"________
Logical Drive 1 Status:Recovering (rebuilding data on a replaced drive)
Logical Drive 1 Blocks to Rebuild: 9.262.848
Logical Drive 2 Status:Ready for recovery
Logical Drive 3 Status:Ready for recovery

_______Time "1"________
Logical Drive 1 Status:OK
Logical Drive 2 Status:OK
Logical Drive 3 Status:Recovering (rebuilding data on a replaced drive)
Logical Drive 3 Blocks to Rebuild: 896.774.736

_______Time "2"________
Logical Drive 1 Status:OK
Logical Drive 2 Status:OK
Logical Drive 3 Status:Recovering (rebuilding data on a replaced drive)
Logical Drive 3 Blocks to Rebuild: 214.992.848

_______Time "3"________
Logical Drive 1 Status:Interim recovery (volume functional, but not fault tolerant)
Logical Drive 2 Status:Interim recovery (volume functional, but not fault tolerant)
Logical Drive 3 Status:Interim recovery (volume functional, but not fault tolerant)

..and the general Controller ERROR REPORT:
Logical drive 1 status = Interim recovery (volume functional, but not fault tolerant)
Port 1I, Box 0, Bay 4 failed - REPLACE (Not ready bad sense)
Logical drive 2 status = Interim recovery (volume functional, but not fault tolerant)
Port 1I, Box 0, Bay 4 failed - REPLACE (Not ready bad sense)
Logical drive 3 status = Interim recovery (volume functional, but not fault tolerant)
Port 1I, Box 0, Bay 4 failed - REPLACE (Not ready bad sense)
Error occurred reading RIS copy from Port 1I, Box 0, Bay 4

I try again , and i had the same results.
Questions:
(1) DO i have a problem on logical drive 3?
(2) Is there any other solution or i have to replace logical drive 3 (--> its also a physical drive).
(3) If i have to replace it, what i have to do? Just replace the drive, and the controller will rebuild the array automatically?

Hi ,

did you try to replace the hard disk in Bay 4 with a new one yet ?

It looks like that is the disk with a problem and when a raid5 reconstruction is tried (rebuild) it aborts after a while because it encounters problems with the media on that disk in Bay 4.

No yet. i have already order a HD.
It seems to agree with you.
So, your answers to my question are:
(1) YES
(2) REPLACE DRIVE
(3) AUTOMATICALLY REBUILD from Controller.
Right?

Teh answers are

1) yes
2) no other solution, replaced physicall disk in bay 4. This will rebuild logical drive 3 and bring it back to a healthy status.
3) normally the array will rebuild the logical drive after you inserted a new disk in bay 4.
