Audible Alarm
The U320-R will sound an alarm if there is a problem with the RAID operation. Corrective actions can be
applied to rectify the problem.
6 Rapid Beeps During Boot Time
6 rapid beeps during boot time is normally associated with SCSI cabling, SCSI termination, or power up
sequence related. Always turn on the U320-R first, then turn on the computer. You might need to
physically remove and re-insert the SCSI connectors and terminators along the SCSI path, this includes the
connectors at the SCSI controller, and at the U320-R.
Check to ensure there are no other SCSI devices on the bus using the same SCSI ID address.
Try removing any other SCSI devices that shares the same SCSI bus as the U320-R, leaving just the U320-
R as the only SCSI device will help to identify if there is a conflict with other devices.
6 Rapid Beeps During Normal Operation
6 rapid beeps during normal operation indicates either there is a SCSI interface issue or a disk drive in the
U320-R has timed out. Check to ensure all SCSI connections are securely in place You might need to
physically remove and re-insert the SCSI connectors and terminators along the SCSI path, this includes the
connectors at the SCSI controller, and at the U320-R.
Slow Beeps
One or more slower beeps
indicate a bad drive or an intermittent drive, the number of beeps indicates
which drive is having problems. When operating in RAID 3@2K mode the U320-R is still available for
normal operation without performance degradation, but the beeps indicate that a drive is down and you are
running without RAID 3 protection. Should another drive fail your are in danger of loosing data.
Constant Solid Beep
This would indicate a drive is down. The SERVICE indicator should also be on. One of the drive indicator
should exhibit a slow blink (one second on then one second off). This drive needs to be serviced. See
Drive Replacement section for more instructions.
