Configuring the RA3000 for the Active Mode of
Operation
If you are upgrading from a single controller storage system, the installed
controller will be in the active/passive mode of operation. To configure the
storage system using a single serial connection, the dual controllers must be
placed in Active/Active mode. Perform the procedure to change your storage
system from “Active/Passive” to “Active/Active” mode of operation.
1. Shutdown the RA3000 storage system, install the second controller, and
restart the system.
2. Connect the host serial port to the serial port connector on the top
controller of the RA3000.
3. Open an HSZ22 monitor utility terminal session. The terminal settings
should be 9600 BAUD, 8 bits, no parity, 1 stop bit, XON/XOFF. If
prompted for a password, enter RAID.
4. When the terminal session is displayed, press the Escape key then press
Shift+7 keys. The controller will respond with banner listing HSZ22
Monitor Utility followed by the Firmware revision number.
5. Select Setup Parameters from the main menu.
6. Select Rdnt Ctrlr Parameters and change the value of Host I/O
Channel 1 to Passive. Press the Ctrl+Z keys to exit.
7. Transfer the serial cable to the serial port on the bottom controller and
press the Ctrl+Z keys. When the Monitor Utility screen appears, press
any key to continue.
8. Select Setup Parameters and then select Rdnt Ctrlr Parameters from
the main menu.
9. Both channels should be displayed as “Passive”. Select the host I/O
channel that was not reconfigured in step 5 and change its value to
Active. Press the Ctrl+Z keys to exit.
10. Restart the controllers by power cycling the RA3000 storage system.
11. Recheck the Rdnt Ctrlr Parameters. The controller values should display
(Active/Passive).
12. Transfer the serial cable to the serial port on the top controller on the
RA3000 and press the Ctrl+Z keys.
13. Check the Rdnt Ctrlr Parameters. The controller values should display
(Passive/Active).
