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 expansion slot (PCI,
PCI-X, or PCIe). To double-check the bus compatibility of your controller, see About Your
RAID Controller on page 15.
● Ensure that your Adaptec RAID controller is firmly seated and secured in the PCI/PCI-X/
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 38 for instructions.)
● SCSI RAID controllers only—Ensure that each SCSI disk drive (or other device) on each
SCSI 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 troubleshooting
information and direction on the Adaptec Web site at www.adaptec.com or the Support
Knowledgebase at ask.adaptec.com.
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 61.) OR
one of the -Select Utilities (see
Modifying Your Controller’s Configuration
on page 88.)
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 page 66).
● If the array was not protected by a hot spare (see page 66).
● If there is a disk drive failure in more than one array simultaneously (see page 66).
● If it is a RAID 0 array (see page 66).
● If multiple disk drives fail within the same array (see page 67).
Note:
In DAS environments, Adaptec Storage Manager uses the term logical drives when
referring to arrays (see page 12).
