Chapter 10: Solving Problems 84

Troubleshooting Checklist

If you encounter difficulties installing or using your Adaptec RAID controller, check these items first:

With your computer powered off, check the connections to each disk drive, power supply, LED connector, and so on.

Try disconnecting and reconnecting disk drives from the Adaptec RAID controller.

Check that your Adaptec RAID controller is installed in a compatible PCIe expansion slot. To double-check the bus compatibility of your controller, see About Your RAID Controller on page 17.

Ensure that your Adaptec RAID controller is firmly seated and secured in the PCIe expansion slot.

If your Adaptec RAID controller is not detected during system boot, try installing it in a different compatible expansion slot. (See page 47 for instructions.)

Did the driver install correctly?

If you have external disk drives (or other devices), are they powered on?

Check the Readme on the installation DVD for compatibility issues and known problems.

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 or the Support Knowledgebase at ask.adaptec.com.

Monitoring Disk Drives Status

You can use the ‘blink’ feature of Adaptec Storage Manager to monitor the status of your SAS and SATA disk drives. When you blink a specific disk drive or set of disk drives, the LED(s) on the selected disk drives flash.

This table describes the LED flash states.

Silencing the Alarm

If your Adaptec RAID controller includes an alarm, the alarm will sound when an error occurs. To silence the alarm, use Adaptec Storage Manager (see Managing Your Storage Space on page 79.) OR SerialSelect (see Modifying Your Controller’s Configuration on page 110.)
