Hello and thanks for looking at this problem.
We took a server down for a scheduled upgrade - adding another 4254R Duplex 14 drive canister - to act as a drive to hold backups of a large multi array system whose tape library was malfunctioning.
While rearranging the array drives, a RAID5 4-disk (call it logicalBroken) volume was accidentally split on two separate controllers, and mixed with two other logical volumes.
This of course is the data that was not being backed up due to a bad AIT drive in the tape library.
The server was booted with the logicalBroken drives split in half – two of the four logicalBroken drives on two separate smart array controllers, one 5302, one 5304. This mixed the logicalBroken drives into to other logical drives.
As soon as the array controllers initialized – the error messages came up, i.e. arrays missing drives, drives at the wrong IDs, ECT.
The server was shutdown immediately.
The logicalBroken drives were put back into their original positions, in the original cage, on the original controller and the server re-started.
logicalBroken, of course, did not come back as a valid logical drive. So here is where I am :
From the Array Diagnostic Utility:
SLOT 4 SMART ARRAY 5300 CONTROLLER ERROR REPORT:
Swapped cables or Configuration error detected.
An unsupported drive rearrangement was attempted. SOLUTION: Power down
system then move the drives back to their original location.
Controller is not configured.
Drive at Port 2, ID 0 indicates it should be located at Port 1, ID 1
Drive at Port 2, ID 1 indicates it should be located at Port 4, ID 1
Drive at Port 2, ID 2 indicates it should be located at Port 1, ID 0
Drive at Port 2, ID 3 indicates it should be located at Port 4, ID 3
RIS copies between drives do not match
No configuration for array accelerator board
I do not want to do anything else to the drives till I can get an expert on this subject to help. I already called HP support and was incredibly unimpressed with the support group available today.
The drives have not been wiped, re-initialized, or booted into an array. So the data **should** still be there.
1) Do we have anybody here that has dealt with this before? Can you edit the RIS Hex and put this back together?
2) Are there any data retrieval companies that may be able to handle this?
3) Does HP have a priority or super support group for smart arrays? Today (Saturday) must not be a good day for support experts at HP . . .
Thanks in advance,
