Dell PowerEdge 2550 - Manual (Page 61)

Is the problem resolved?
Yes. You have fixed the problem.
No. Go to step 10.
10. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet. Then open the system doors.
11. Remove the tape drive. Then verify that the tape drive is configured for a unique SCSI ID number and that the tape drive is terminated or not
terminated as appropriate. See the documentation for the tape drive for instructions on selecting the SCSI ID and enabling or disabling termination.
Is the tape drive configured correctly?
Yes. Go to step 14.
No. Go to step 12.
12. Reconfigure the tape drive's SCSI ID and termination settings as appropriate. Reinstall the tape drive, close the system doors, reconnect the system to
the electrical outlet, and turn it on.
Is the problem resolved?
Yes. The tape drive was configured incorrectly. You have fixed the problem.
No. Go to step 13.
13. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet. Then open the system doors.
14. Replace the SCSI cable that connects the tape drive to the SCSI host adapter. Close the system doors, reconnect the system to the electrical outlet,
and turn it on.
Is the problem resolved?
Yes. You have fixed the problem.
No. See " Getting Help " for instructions on obtaining technical assistance.
Troubleshooting SCSI Hard-Disk Drives
Hard-disk drive problems can be caused by a number of conditions, including problems with the drive itself, the SCSI backplane board, the optional SCSI
daughter boards, or a cable connected to the SCSI backplane board.
The SCSI backplane board monitors the SCSI hard-disk drives connected to the backplane board. In the event of a drive failure, systems using the optional
integrated redundant array of independent disks (RAID) controller or optional PERC controller card will issue the following signals using the drive indicator
lights adjacent to each SCSI hard-disk drive:
l If a drive shows signs of imminent failure, the drive online indicator stays on and the drive failure indicator blinks on briefly each second.
l If a drive has failed, the drive online indicator turns off. The drive failure indicator turns on, and blinks off briefly each second.
Other drive indicator patterns are listed in Table 3 -3 , "SCSI Hard-Disk Drive Indicator Patterns."
To troubleshoot a hard-disk drive problem, perform the following steps.
1. If the integrated SCSI host adapter is being used to control the SCSI backplane board, reboot the system and press <F2> to enter the System Setup
program.
Is the integrated SCSI controller enabled?
Yes. Go to step 3.
No. Go to step 2.
2. Enable the integrated SCSI controller, and reboot the system.
Is the problem resolved?
Yes. You have fixed the problem.
No. Go to step 3.
3. Verify that the SCSI device drivers are installed and configured correctly. See "Installing and Configuring SCSI Drivers" in the User's Guide to determine
which drivers are required and how they should be installed and configured.
Are the required SCSI device drivers installed and configured correctly?
Yes. Go to step 5.
WARNING: This troubleshooting procedure can destroy data stored on the hard-disk drive. Before you proceed, make sure you have backed up all
files on the hard-disk drive.
