10 Solving ProblemsThis chapter provides basic troubleshooting information and solutions for solving controller problems.Troubleshooting ChecklistIf 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, LEDconnector, 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. Todouble-check the bus compatibility of your controller, see About Your RAID Controller on page 16.• 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 differentcompatible expansion slot. (See Installing the Controller on page 27 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 anddirection on the Adaptec Web site at www.adaptec.com or the Support Knowledgebase atask.adaptec.com.Monitoring Disk Drives StatusYou can use the ‘blink’ feature in maxView Storage Manager to monitor the status of your SAS and SATAdisk drives. When you blink a specific disk drive or set of disk drives, the LED(s) on the selected diskdrives flash.This table describes the LED flash states.LED Flash StateSlot StateController Device StateOnDevice is faultyFailedSlow flashDevice is rebuildingRebuildingFast flashIdentify the deviceBlinkOffNo errorOtherFor more information about using maxView Storage Manager to monitor your disk drives, refer to themaxView Storage Manager User’s Guide or the online Help.Silencing the AlarmIf your Adaptec RAID controller includes an alarm, the alarm will sound when an error occurs. To silencethe alarm, use maxView Storage Manager (see Managing Your Storage Space on page 54.) OR the ARCutility (see Modifying Your Controller’s Configuration on page 75.)Recovering from a Disk Drive FailureThis 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 page57.• If the array was not protected by a hot spare, see Failed Disk Drive Not Protected by a Hot Spare onpage 57.• If there is a disk drive failure in more than one array simultaneously, see Failure in Multiple ArraysSimultaneously on page 57.56Proprietary and Confidential to PMC-Sierra, Inc.Document No.: CDP-00277-01-A Rev.
