Dead Channel Service Procedure
Use this procedure when, on one or more channels, all configured (ONL/HSP) drives are shown as DDD, and all RDY/SBY/DHS devices are shown as EMP.
Before continuing, verify that the hard drive enclosure is powered on. If the drives in the enclosure have been marked DDD because the enclosure was powered off, power-on the enclosure, then import the configuration from the drives by performing the following actions:
+---+
|001|
+---+
DOES THIS SERVERAID ADAPTER/CONTROLLER HAVE MORE THAN ONE CHANNEL?
Yes No
| |
| +-+-+
| |002| ServeRAID adapter/controller has only one channel and it is failing.
| +---+
| - Follow the channel trouble shooting procedure.
| See Channel Troubleshooting Procedure
| - Move adapter to a different PCI slot.
| If problem persists, replace the adapter/controller.
+-+-+
|003|
+---+
DO THE OTHER CHANNELS ON THE SERVERAID ADAPTER/CONTROLLER HAVE ANY DEVICES CONNECTED?
Yes No
| |
| +-+-+
| |004| Do not press F5, since this changes the customer's configuration.
| +---+
| - Connect the failing channel cable to one of the
| other channel connectors on the adapter/controller
| and reboot.
|
| You should get new error messages now for the moved channel in the form of
| 'Following drives not responding...', and 'Following drives found in new location...'.
|
| If you get '...drives not responding...' and do not get the
| '...drives in new location...',
| there is a problem on the SCSI channel outboard of the adapter/controller
| that prevents the adapter/controller from communicating with the devices
| attached to that channel.
|
| Go to Channel Troubleshooting Procedure to resolve the problem.
|
| - or -
|
| If you get '...drives not responding...' and '...drives in new location...',
| reconnect the cable to the original channel connector and reboot.
| If original message appears, the original channel on the adapter/controller is defective.
| Replace adapter/controller.
+-+-+
|005|
+---+
DOES THE STATUS FOR THESE DRIVES APPEAR CORRECT?
Yes No
| |
| +-+-+
| |006| Status is incorrect for multiple channels.
| +---+
| - Verify that devices on channel are powered up and properly connected.
| - Move adapter to a different PCI slot.
|
| If problem persists, replace the adapter/controller.
+-+-+
|007|
+---+
Do not press F5, since this changes the customer's configuration.
- Disconnect one of the correctly-operating channel connectors at the adapter/controller
and connect it to the failing adapter/controller channel.
- Reboot the system.
You should get new error messages now for the moved channel in the form of
'Following drives not responding...', referring to original and moved channels,
and 'Following drives found in new location...'.
If you get '...not responding...', referring to original and moved channels,
and do not get the 'Following drives found in new location...' message,
then this channel on the adapter/controller is defective.
Replace adapter/controller.
- or -
If you get '...new location...', this channel on the adapter/controller is working correctly.
Continue at Step 008.

+---+
- Connect the original failing channel cable to the connector from which
the working channel was removed and reboot.
If you get the '...drives not responding' message, and do not get the
'Following drives found in new location...', there is a problem on the
SCSI channel outboard of the adapter/controller that prevents the adapter/controller
from communicating with the devices attached to that channel.
Go to Channel Troubleshooting Procedure to resolve the problem.
- or -
If you get the '...drives in new location...' message, the problem has apparently resolved itself.
Restore the channel connections to original locations and reboot.
If the original problem persists, suspect a problem in the mating
of the cable and adapter/controller connectors.
