Troubleshooting Checklist

If you encounter difficulties installing or using your HostRAID controller, check these items 
first:

●

With your computer powered off, check the connections to each disk drive, the power 
supply, the LED connector, and so on.

●

Try disconnecting and reconnecting disk drives from the HostRAID controller.

●

Check that your HostRAID controller is installed in a compatible expansion slot. To 
double-check the bus compatibility of your controller, see 

.

●

Ensure that your HostRAID controller is firmly seated and secured in the PCI, PCI-X, or 
PCIe expansion slot.

●

If your HostRAID controller is not detected during system boot, try installing it in a 
different expansion slot. See 

 for instructions.

●

Did the driver install correctly? 

If you are still unable to resolve a problem, you can find additional troubleshooting 
information and direction on the Adaptec Web site at 

 and the Adaptec 

Support Knowledgebase at

Recovering from a Disk Drive Failure

This section explains how to recover when a disk drive fails:

●

If the array was protected by a hot spare, see next section.

●

If the array was not protected by a hot spare, see 

.

●

If there is a disk drive failure in more than one array simultaneously, see 

●

If it is a RAID 0 array, see 

.

●

If multiple disk drives fail within the same array, see 

.

Note: 

Adaptec Storage Manager uses the term logical drives when referring to arrays. 

Failed Disk Drive Protected by a Hot Spare

When an array is protected by a hot spare, if a disk drive in that array fails the hot spare is 
automatically incorporated into the array and takes over for the failed drive. 

To recover from the failure, remove and replace the failed disk drive (following manufacturer’s 
instructions).

Failed Disk Drive Not Protected by a Hot Spare

If a disk drive fails in an array that is not protected by a hot spare, replace the failed drive. The 
controller detects the new disk drive and rebuilds the array.
