Chapter 5 Troubleshooting
This chapter is divided into two main sections: basic troubleshooting and advanced
troubleshooting.
5.1 Basic Troubleshooting
1. SCSI card could not detect Mirror Smart or Mirror Disk
l Confirm if Mirror Smart and every hard drive were connected well, and the
power switch is ON.
l Confirm if Mirror Smart was connected firmly to the SCSI card by the SCSI
cable.
l Confirm if a terminator was added to the end of SCSI bus.
l Confirm if the ID of Mirror Smart or a SCSI device is unique.
l Confirm if every hard drive’s jumper was set to Master/Single or Cable
Select.
2. SCSI card detected an unknown device or a wrong HDD
Usually it is because that Mirror Smart hasn’t connected with any hard drive. Ac-
cordingly, the device which the SCSI card detected is Mirror Smart’s controller. As
for the detection of a wrong HDD, it is perhaps that the SCSI cable is bad, or the
hard drive is not in the support list. Please visit ACARD’s website to get the newest
support list, or download the newest firmware of Mirror Smart to support.
3. Mirror Smart produced an unknown beep or its handle ejected
You can judge the cause according to the length or frequency of a beep. Please
refer to the end of Chapter 3. As for the ejecting of handle, it means that a hard drive
went wrong. Please get a new hard drive. Mirror Smart will rebuild the data into the
new hard drive automatically. If there are other problems such as fan failure, high
temperature, etc., please contact the distributor or ACARD’s technical personnel.
4. An error happened in accessing Mirror’s hard drives or no access
l Confirm if the connection of Mirror Smart and SCSI cable is loose.
