Compaq Infortrend manual Starting the Redundant Controllers, Creating Primary and Secondary ID

Enter a hex number from 0 to FFFFF and press [ENTER]. The value you enter should be different for each controller.

Power off controller 1, then power on controller 2. Set controller 2 to "Secondary" as described above.

Power off controller 2.

Starting the Redundant Controllers

Power on all hard drives and the two controllers. If drives are installed in a drive enclosure, wait for the drives to be ready, then power on the enclosure where the RAID controllers are installed.

The message "RC (redundant controller) connecting... <ENT> to cancel" will appear on the LCD display of the two controllers. After a few seconds, the Primary controller will startup with the model number and firmware version displayed on the LCD, while the Secondary controller will display the message "RC Standing By.. <ENT> to Cancel" on its LCD. A few seconds later, the LCD display on the Secondary controller will be similar to the LCD display on the Primary controller. The upper right corner of LCD will then be displaying a “P” or ”S,” meaning “Primary” or “Secondary” respectively.

<ENT> to cancel

During normal operation, the controllers continuously monitor each other. Each controller is always ready to take over for the other controller in an unlikely event of a controller failure.

The Primary and Secondary controllers synchronize each other’s configurations at frequent intervals through the communications channel(s).
