Setting or Modifying the RAID Mode
NOTE: Setting or modifying the RAID mode destroys all data.
1.Follow the procedure for resetting the RAID Mode.
2.Power down the unit and set the dip switch to the desired RAID Mode.
3.While holding the SET button with a ballpoint pen, turn the unit on. A long beep will sound from the Port Multiplier. The SET button may be released once the long beep stops.
If instead of a long beep the Port Multiplier sounds a series of short beeps, an error has occurred during configuration of the array.
Windows users may install the JMicron HW RAID Manager application located on the SATA Controller CD. In the CD, browse to Configuration Utilities → JMB393. The JMicron HW RAID Manager can be used to create, modify, and monitor the health status of the RAID drives, and provide status alerts. When configuring the RAID mode using the RAID Manager application, it is strongly recommended to leave the dip switch in the factory default setting.
Using identical drives for all settings other than JBOD or LARGE is strongly recommended. Creating a LARGE array using drives that have different properties will use all space on all members, and performance will match that of the member in use during any particular I/O operation. Creating a RAID using drives that are not all the same size will result in all members using only as much space as the smallest member. Creating a RAID using drives that have different performance will degrade the overall performance of the array.
BZS Switch (SW1:1):
The BZ switch is used to silence the audible alarm buzzer. The OFF position permits the audible alarm, and the ON position silences the audible alarm. The BZ switch has immediate effect.
EZ Switch (SW1:2):
The EZ (spare) switch inhibits spares when ON. When in the OFF position, all individual drives (not defined as members of an array) are considered spare. Should a RAID become degraded, when the EZ switch is in the OFF position a spare drive will be used automatically to rebuild the RAID, if present. EZ mode is determined when the unit is powered up. Changing the switch will have no effect until the unit has been
