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 About Your HostRAID
Controller on page 12.
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 page 24 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 page 51).
If there is a disk drive failure in more than one array simultaneously (see page 51).
If it is a RAID 0 array (see page 51).
If multiple disk drives fail within the same array (see page 51).
Note:
Adaptec Storage Manager uses the term logical drives when referring to arrays
(see page 11).
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).
