(3)Drive positions appear to have changed – Run Drive Array Advanced Diagnostics if previous positions are unknown. Then turn system power OFF and move drives to their original positions.
(4)Configuration information indicates drive positions beyond the capability of this controller. This may be due to drive movement from a controller that supports more drives than the current controller.
(5)Configuration information indicates drives were configured on a controller with a newer firmware version.
Audible Beeps: None
Possible Cause: Drive array configuration not detected.
Action:
•Run ACU ("Array Configuration Utility" on page 54).
•Power down the system and check SCSI cable connections to be sure the drives are connected properly.
•Run ADU ("Array Diagnostic Utility" on page 63) if previous positions are unknown. Then, turn the system power off and move the drives to their original positions.
•To avoid data loss, update the controller firmware to the same or later version on the original controller ("Firmware maintenance" on page 65).
Audible Beeps: None

...The following SCSI drive(s) need Automatic Data Recovery: SCSI Port Y: SCSI ID Z
Select F1 to continue with recovery of data to drive. Select F2 to continue without recovery of data to drive.
Audible Beeps: None
Possible Cause: A failed or replacement drive has not yet been rebuilt.
Action:
•Perform one of the following actions:
•Press the F1 key to continue with recovery of data to the drive. Data will be automatically restored to drive X when a failed drive has been replaced, or to the original drive if it is working again without errors.
•Press the F2 key to continue without recovery of data to the drive. The failed drive will not be rebuilt and the system will continue to operate in a failed state of Interim Data Recovery Mode.
•Replace the failed drive and press the F1 key to rebuild the array. If the drive rebuild is not successful or is aborted because the system rebooted before the rebuild of the drive completed, another version of the 1786 POST error message will be displayed. Refer to the following message.
