Second Controller Option 5-13

Your storage system is now properly configured for dual controller operation from a single serial host port. Proceed to the next section to configure the controllers.

Configuring the Dual Controllers

In order to create a virtual disk, a serial connection must be made to the controller. The serial connection provides a local connection to the RA3000 (HSZ22) controller. To configure the controller, perform the following steps:

1.Ensure the RA3000 Storage System is turned off.

2.Connect the serial cable between the host serial connector and the top controller’s serial port connector.

3.Power on the RA3000 storage system.

4.Open the StorageWorks management utility.

5.Select the Serial button in the HSZ22 Management window.

6.Select the serial port available on the host’s workstation and then click on the Connect button.

7.When the second connection window appears, select Cancel. Once the connection is established, a storage window will appear with the connected port identified at the top of the window.

8.From the Storage menu, select Add Virtual Disk. Select JBOD from the menu (you may select any RAID level you wish) and then select Next.

9.Select Drive from the window Devices Available to Create a New Virtual Disk and then select Next.

10.Select Add and then select Next.

11.A window is displayed prompting for selection of the host port that the JBOD should be created on. There is a single connection to the controller so only one host port will be available. Select Next.

12.Choose a LUN number and enable the write-back cache.

13.Select Next and then Finish.

14.You have now created one Virtual Device (JBOD) on the top controller. Disconnect the serial cable from the top controller and reconnect the cable to serial port connector on the bottom (redundant) controller.

15.Close and reopen the StorageWorks window and repeat steps 4 through 13.
