Two days ago, we had a server go down on us. It was powered down for routine maintenance and afterward would not power back on. After troubleshooting it was determined that the motherboard had fried. We ordered a new motherboard and installed it.
The system now powers on but it is having problems recognizing our scsi drives. We have 6 hot swappable drives on a backplane. The drives on the array are separated into two logical drives. One RAID 0 (2 drives) and one RAID 5 (4 drives).
Here is the system information:
IBM eServer xSeries225 Model 8649
IBM ServeRAID-6i controller card
6 u320 SCSI drives
Operating System is Microsoft Server 2003 Standard with Exchange Server 2003 Std Installed
Upon boot the system gave us multiple problems, most of which were fixed by setting the system time
First time it booted after checking RAID config for the controller, got a warning: 6i controller FAILED one or more drives changed or missing.
We rebooted the sytem rather than make any changes thaty could screw it up worse and the second time it booted it gave this warning
Controller OK Drives not detected, check cable or connectors
The system seems to alternate between these two errors almost randomly every time we try to boot it.
We are confident that the drives didn't get scrambled around. Is there a configuration step we are missing because we put in a new motherboard? Is there some way to boot from CD and display the config info from the drives and get it going?
Let us know if you smart people out there need more info to solve this problem.
