Chapter 11: Solving Problems ● 45 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 23 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 46). ● If there is a disk drive failure in more than one array simultaneously (see page 46). ● If it is a RAID 0 array (see page 46). ● If multiple disk drives fail within the same array (see page 46). 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).

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 23
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

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 46
).
●
If there is a disk drive failure in more than one array simultaneously (see
page 46
).
●
If it is a RAID 0 array (see
page 46
).
●
If multiple disk drives fail within the same array (see
page 46
).
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).
