will begin the rebuild of the RAID. There will be a timer in the bottom right corner of the LCD that will give
an approximate time to completion. After the rebuild is finished the RTX400-QR will need to be rebooted.
A rebuild with 250GB drives will take approximately 75 minutes.
The loss of two drives will result in a RAID failure. New drives will need to be inserted, preferably the
same model of the drives that are getting replaced. Open WiebeTech Configurator 2.0 to set up a new
RAID. (see section 4.1.2)
Note: A degraded RAID 5 will stay mounted and can continue to transfer data. However, WiebeTech
recommends disconnecting the unit during a rebuild if at all possible.
5.3.2.5.1 RAID 5 with Hot Spare
If the RAID 5 is “3 + Host Standby” then no manual rebuild is necessary. The hot spare will automatically
be added to the RAID by rebuilding. At the end of the rebuild a new disk will need to be added, preferably
the same model of the drive that is getting replaced. The RTX will prompt you to “Add new disk” after
insertion. Select “Yes” (left). That disk will be the new hot spare for the RAID.
5.3.2.6 Degraded: RAID 10
The loss of a drive in a RAID 10 will result in a degraded RAID state. The LCD display will show a
“Degraded” state and the RAID LED (yellow) will flash. The RAID can be rebuilt by removing the failed
drive and inserting a new drive, preferably the same model of drive that is getting replaced. After a new
drive is inserted the LCD display will prompt you to “Add new disk.” Select “Yes” (left) and it will begin the
rebuild of the RAID. There will be a timer in the bottom right corner of the LCD that will give an
approximate time to completion. After the rebuild is finished the RTX400-QR will need to be rebooted. A
rebuild with 250GB drives will take approximately 75 minutes.

6. Usage with Mac and Windows Operating Systems
6.1 Usage with Macintosh Computers
6.1.1 Compatibility
The RTX400-QR is compatible with Mac OS X. No drivers are needed.
6.1.2 Using Volumes
When you connect the unit to the Mac for the first time and turn on the power, you’ll
probably see a message saying that the disk is unreadable. This is because you
must format the volume before using it. The easiest way to do this is to use Mac OS
X’s Disk Utility. If you plan to use the unit on both Macs and PCs, select “MS DOS
File System” as the format type. If you only plan to use the unit on Macs, then select
“Mac OS Extended”. After the volume is formatted, an icon representing the drive
volume will appear (“mount”) on the desktop. You can now use the volume just like
an internal hard drive.
Eject the volume before powering down the unit by dragging the volume’s icon to the trash bin, or by
selecting the volume then pressing Command-E. Shutting down the unit without first ejecting the volume
can result in data loss.
