Troubleshooting Checklist

If you encounter difficulties installing or using the Sun StorageTek SAS RAID

Internal HBA, check these items first:

■ With the 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 HBA.

■ Check that the HBA is installed in a compatible expansion slot (x8 PCI Express).

■ Ensure that the HBA is firmly seated and secured in the expansion slot.

■ If the HBA is not detected during system boot, try installing it in a different

compatible expansion slot.

■ 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
