Adaptec ATA II 1220SA manual Troubleshooting Checklist, Recovering from a Disk Drive Failure

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).
