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).
