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, to the power
supply, to the LED connector, and so on.
Try disconnecting and reconnecting disk drives from the Adaptec RAID controller.
● Check that your Adaptec RAID controller installed in a compatible expansion slot (PCI,
PCI-X, or PCI-E). To double-check the bus compatibility of your controller, see About Your
RAID Controller on page 16.
● Ensure that your Adaptec RAID controller firmly seated and secured in the PCI/PCI-X/
PCI-E expansion slot.
● If your Adaptec RAID controller is not detected during system boot, try installing it in a
different compatible expansion slot. (See page 32 for instructions.)
● SCSI RAID controllers only—Ensure that each SCSI disk drive (or other device) on each
SCSI bus assigned a unique SCSI ID.
Check that termination 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 52.)
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 57).
● If the array was not protected by a hot spare (see page 57).
● If there is a disk drive failure in more than one array simultaneously (see page 57).
● If it is a RAID 0 array (see page 57).
● If multiple disk drives fail within the same array (see page 58).
Note:
Adaptec Storage Manager uses the term logical drives when referring to arrays (see
page 12).
