Dell PowerEdge 2650 - Manual (Page 46)

1. Remove the tape that was in use when the problem occurred and replace it with a tape that you know is not defective.
2. Verify that any required SCSI device drivers are installed on the hard drive and are configured correctly.
For information on device drivers for the system's integrated SCSI controller, see "Installing and Configuring SCSI Drivers" in the User's Guide.
3. Reinstall the tape-backup software as instructed in the tape-backup software documentation.
4. Check the cable connections to the drive.
a. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.
b. Check the SCSI cable connection from the tape drive to the SCSI controller card installed in the system.
c. Check the AC power cable connection to the tape drive.
5. 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.
6. See the documentation for the tape drive for instructions on selecting the SCSI ID and enabling or disabling termination.
7. Reconnect the system to the electrical outlet and turn on the system.
8. If the problem is not resolved, see " Getting Help " for instructions on obtaining technical assistance.
Troubleshooting Hard Drives
Problem
l Faulty hard drive
l Faulty SCSI backplane board
l Faulty or loose SCSI cable connections
l Hard-drive status indicator signifies a problem with the drive
l Front-panel status LCD indicating a problem with hard drives
Action
1. Reboot your system and enter the SCSI configuration utility by pressing , , or , depending on your SCSI or RAID
controller.
2. Ensure that the primary SCSI channel is enabled, and reboot the system.
See the documentation supplied with the controller for information on the configuration utility.
3. Verify that the device drivers are installed and configured correctly (see the operating system's documentation).
4. Remove the hard drive and install it in the another drive bay.
5. If the problem is resolved, reinstall the hard drive in the original bay.
If the hard drive functions properly in the original bay, the drive carrier could have intermittent problems. Ensure that the drive is properly mounted on
the drive carrier (see "
Installing a SCSI Hard Drive " in "Installing Drives").
If the drive carrier still does not function properly in the original bay, the SCSI backplane board has a defective connector. See " Getting Help " for
instructions on obtaining technical assistance.
6. If a RAID controller card is installed, check the SCSI cable connections inside the system:
a. Turn off the system, including any attached peripherals, and disconnect the system from its electrical outlet.
b. Remove the cover (see " Removing the Cover ").
c. Check the SCSI cable connection to the RAID controller card (see the RAID controller's documentation for detailed information).
d. Replace the back cover (see " Replacing the Cover ").
e. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
7. Partition and logically format the hard drive. If possible, restore the files to the drive.
To partition and logically format the drive, see the operating system documentation.
If the problem is not resolved, see " Getting Help " for instructions on obtaining technical assistance.
NOTICE: This troubleshooting procedure can destroy data stored on the hard drive. Before you continue, back up all the files on the hard drive.
NOTE: If a drive shows signs of imminent failure, the status indicator blinks green, then amber, and then off, repeating this sequence every two
seconds. If a drive has failed, the status indicator blinks amber four times per second.
NOTE: To operate the SCSI backplane in a 1 x 5 configuration, ensure that the SCSI backplane daughter card is not installed. To operate the SCSI
backplane in a 2/3 split configuration, ensure that the SCSI backplane daughter card is installed (see " Installing a SCSI Backplane Daughter Card "
in "Installing Drives").
