Chapter 10: Solving Problems ● 64Troubleshooting ChecklistIf you encounter difficulties installing or using your ICP RAID controller, check these itemsfirst:● 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 ICP RAID controller.● Check that your ICP RAID controller is installed in a compatible expansion slot (PCI, PCI-X, or PCIe). To double-check the bus compatibility of your controller, see About YourRAID Controller on page 15.● Ensure that your ICP RAID controller is firmly seated and secured in the PCI/PCI-X/PCIeexpansion slot.● If your ICP RAID controller is not detected during system boot, try installing it in adifferent compatible expansion slot. (See page 37 for instructions.)● SCSI RAID controllers only—Ensure that each SCSI disk drive (or other device) on eachSCSI bus is assigned a unique SCSI ID.Check that termination is set correctly on each SCSI bus.● Did the driver install correctly?● If you have external disk drives (or other devices), are they powered on?If you are still unable to resolve a problem, you can find additional troubleshootinginformation and direction on the ICP Web site at www.icp-vortex.com or the SupportKnowledgebase at ask.adaptec.com.Silencing the AlarmIf your ICP RAID controller includes an alarm, the alarm will sound when an error occurs. Tosilence the alarm, use ICP Storage Manager (see Managing Your Storage Space on page 60.) OR oneof the -Select Utilities (see Modifying Your Controller’s Configuration on page 87.)Recovering from a Disk Drive FailureThis section explains how to recover when a disk drive fails:● If the array was protected by a hot spare (see page 65).● If the array was not protected by a hot spare (see page 65).● If there is a disk drive failure in more than one array simultaneously (see page 65).● If it is a RAID 0 array (see page 65).● If multiple disk drives fail within the same array (see page 66).Note: In DAS environments, ICP Storage Manager uses the term logical drives when referring toarrays (see page 12).
