If you encounter a problem while using the ACUTA 4/4S, check this section for help.
1. When I lock a drive carrier with a disk drive in place, the red disk activity indicator
turns on and an alarm beep sounds. Why?
Ö Make sure the IDE and power connectors of the DISK are connected firmly to their
counterparts inside the drive carrier.
Ö Ensure the DISK is set as single-master.
Ö Change the disk drive with a new one and try again.
Ö Exchange the top and bottom drive carriers and try again to determine if the carrier
itself is faulty.
Ö If all of the above steps fail, contact your vendor.
2. How can I turn off the alarm beep sound when there is a hard disk failure?
Ö Unlock the drive carrier of the failed disk, or
Ö Press the mute button.
3. I have connected the ACUTA 4/4S subsystem, but it does not appear in the
motherboard BIOS. Why?
Ö Ensure that an array is initialized completely.
4. Why does ACUTA 4/4S not recognize the DISKs?
Ö There may be an DISK jumper-setting problem. Make sure all drive jumpers are set
to "Single-master". Please refer to FAQ 1.
5. How should I react to disk failure?
Ö For a RAID 5/RAID 0+1 array, you should replace the failed disk. Data rebuilding will
then begin.
Ö For a RAID 5+hot spare array, data will be rebuilt automatically to the hot spare disk.
There is no need to immediately replace the failed drive.
Ö The capacity of new DISK you installed must equal or larger than the smallest DISK
in ACUTA 4/4S. Otherwise, it will be rejected by ACUTA 4/4S, though it has no any
damage.
