10 Solving Problems

This chapter provides basic troubleshooting information and solutions for solving controller problems.

Troubleshooting Checklist

If you encounter difculties installing or using your Adaptec RAID controller, check these items rst:

• 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 rmly 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 Installing the Controller on page 36 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 nd 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 in maxView Storage Manager to monitor the status of your SAS and SATA

disk drives. When you blink a specic disk drive or set of disk drives, the LED(s) on the selected disk

drives ash.

This table describes the LED ash states.

OffNo errorOther

For more information about using maxView Storage Manager to monitor your disk drives, refer to the

maxView Storage Manager User’s Guide or the online Help.

Silencing the Alarm

If your Adaptec RAID controller includes an alarm, the alarm will sound when an error occurs. To silence

the alarm, use maxView Storage Manager (see Managing Your Storage Space on page 64.) OR the ARC

utility (see Modifying Your Controller’s Conguration on page 87.)

Recovering from a Disk Drive Failure

This section explains how to recover when a disk drive or SSD fails:

• If the array was protected by a hot spare, see Failed Disk Drive Protected by a Hot Spare on page

67.

• If the array was not protected by a hot spare, see Failed Disk Drive Not Protected by a Hot Spare on

page 67.

• If there is a disk drive failure in more than one array simultaneously, see Failure in Multiple Arrays

Simultaneously on page 67.
