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 (PCI-X). 
To double-check the bus compatibility of your controller, see 

.

●

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

●

If your HostRAID controller is not detected during system boot, try installing it in a 
different PCI-X 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 www.adaptec.com and the Adaptec 
Support Knowledgebase at ask.adaptec.com.

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).
