7. Changing RAID configuration

The RP2 supports several RAID configurations. Those configurations are set at the factory but can

easily be changed again in the field by two methods. One method is to use the jumpers on the back of

the RP2 itself. The other is to use a free windows program called HW RAID Manager (available for

download from our website). Using the jumper method allows quick change without running the

program and maybe the only way in installations which a windows machine is not connected to the

RAIDFrame.

7.1. Using Jumpers to change your RAID settings

On the back of the RP2 is a small cutout with two .100" standard center pin jumpers. Each time the

RP2 is inserted, it checks to see if these jumpers have changed from the last time. If they have, it

erases the current configuration and sets up the new configuration.

WARNING! CHANGING THESE

JUMPERS WILL CAUSE COMPLETE DATA LOSS! Only move them if loosing your data is

acceptable.

Once a RAID type has been set, that type is branded onto the hard drives. Even though the jumpers

may change thereafter, the RAID type will not change while a branded drive set is in the RP2. RAID

type branding has priority over the jumpers. However, should the jumpers be set to the Single Drive

setting, the branding is removed and the next RAID type change will become the new branding.

For example, if you had 3 1TB drives in a RAID 5 configuration that you wished to change to RAID 0,

you would first put the jumpers in the Single Drive setting (remove them both). Then install the RP2

and let it power up. Once you hear the beep, it will have cleared the RAID branding from the drives

and only a single drive's capacity will be shown to the system. Then, remove the RP2, set the jumpers

to the RAID 0 setting. Insert the RP2 again. When you hear the beep again, it will have reconfigured

itself to the RAID 0 setting. Any changes to the jumpers after this will have no effect on this drive set

until it is placed in the Single Drive setting again.

See Figure 5 and 6 below for different RAID settings.
