Initializing the SAN Volume Controller 2145-CG8 system from the front panel

After you install all nodes, use the front panel of one of the nodes to start the configuration of the system. Complete these steps on only one node. After you complete these steps on the front panel for one node, use the management GUI to complete system configuration by adding the remaining nodes to the system.

Before you begin

Before you create a system, ensure that all SAN Volume Controller nodes are correctly installed, cabled, and powered on.

When you create the system, you must specify either an IPv4 or an IPv6 system address for port 1. After the system is created, you can specify additional IP addresses for port 1 and port 2 until both ports have an IPv4 address and an IPv6 address.

If you choose to have the IBM® service representative or IBM Business Partner initially create the system, you must provide the following information before you configure the system:
  • For a system with an IPv4 address:
    • Management IPv4 address
    • Subnet mask
    • Gateway IPv4 address
  • For a system with an IPv6 address
    • Management IPv6 address
    • IPv6 prefix
    • Gateway IPv6 address
Define these addresses on the Configuration Data Table planning chart, which is used when you install a clustered system.
Attention: The management IPv4 address and the IPv6 address must not be the same as any other device accessible on the network.

The IBM service representative or IBM Business Partner uses the front panel of the node to enter the information that you have provided. The default system superuser password is passw0rd. The password and the IP address are used to connect to the management GUI to finalize creating the system.

About this task

In the following figure, bold lines indicate that the select button was pressed. Lighter lines indicate the navigational path (up or down and left or right). The circled X indicates whether the select button is pressed, an action occurs that uses the data that is entered.

Use the front panel and follow these steps to create and configure the system:

Procedure

  1. Choose a node that you want to make a member of the system that you are creating.
    Note: You add nodes by using a different process after you successfully create and initialize the system.
  2. Press and release the up or down button until Action? is displayed.
  3. Press and release the select button.
  4. Depending on whether you are creating a system with an IPv4 address or an IPv6 address, press and release the up or down button until either New Cluster IP4? or New Cluster IP6? is displayed.
  5. Press and release the select button.
  6. Press and release the left or right button until either IP4 Address: or IP6 Address: is displayed.
    Figure 1. New Cluster IP4? and New Cluster IP6? options on the front-panel display
    Shows the sequence of the Cluster IPv4? and cluster IPv6? options on the front-panel display
  7. Press and release the select button.
    • If the Cluster IPv4? or Cluster IPv6? actions are not displayed, this node is already a member of a system. Press and release the up or down button until Actions? is displayed. Press and release the select button to return to the Main Options menu. Press and release the up or down button until Cluster: is displayed. The name of the system that the node belongs to is displayed on line 2 of the panel. If you want to delete the node from this system, see the instructions for deleting a node from a system . If you do not want to delete this node from the system, review the situation and determine the correct nodes to include in the new system. Then go to step 1 and begin again.
    • If you are creating a system with an IPv4 address and IP4 Address: is displayed on line 1 of the panel, go to Creating a system with an IPv4 address to complete the steps for creating a system.
    • If you are creating a system with an IPv6 address and IP6 Address: is displayed on line 1 of the panel, go to Creating a system with an IPv6 address, to complete the steps for creating a system.

Creating a system with an IPv4 address

The management IP address can be an IPv4 or IPv6 address.

About this task

The following steps provide the information to complete the task for creating a system with an IPv4 address.
  1. You might need to press the select button to enter edit mode. The first IPv4 address number is shown.
  2. Press the up button if you want to increase the value that is displayed; press the down button if you want to decrease that value. If you want to quickly increase the highlighted value, hold the up button. If you want to quickly decrease the highlighted value, hold the down button.
    Note: To change the address scrolling speed, see the note at the end of this topic.
  3. Press the right or left buttons to move to the number field that you want to update. Use the right button to move to the next field and use the up or down button to change the value of this field.
  4. Repeat step 3 for each of the remaining fields of the IPv4 Address.
  5. After you change the last field of the IPv4 Address, press the select button to leave edit mode. Press the right button to move to the next stage. IP4 Subnet: is displayed.
  6. Press the select button to enter edit mode.
  7. Use the up or down button to increase or decrease the value of the first field of the IPv4 Subnet to the value that you choose.
  8. Use the right button to move to the next field and use the up or down buttons to change the value of this field.
  9. Repeat step 8 for each of the remaining fields of the IPv4 Subnet.
  10. After you change the last field of IPv4 Subnet, press the select button to leave edit mode. Press the right button to move to the next stage.
  11. Press the select button to enter edit mode. Press the right button. IP4 Gateway: is displayed.
  12. Press the up button if you want to increase the value that is displayed; press the down button if you want to decrease that value. If you want to quickly increase the highlighted value, hold the up button. If you want to quickly decrease the highlighted value, hold the down button.
  13. Use the right button to move to the next field and use the up or down button to change the value of this field.
  14. Repeat step 13 for each of the remaining fields of the IPv4 Gateway.
  15. Press and release the right button until Confirm Create? is displayed.
  16. Press the select button to complete this task.
After you complete this task, the following information is displayed on the service display screen:
  • Cluster: is displayed on line 1.
  • A temporary, system-assigned clustered system name that is based on the IP address is displayed on line 2.
Note: To disable the fast increase and decrease address scrolling speed function by using the front panel, press and hold the down arrow button, press and release the select button, and then release the down arrow button. The disabling of the fast increase and decrease function lasts until system creation is completed or until the feature is enabled again. If you press and hold the up or down arrow button while the function is disabled, the value increases or decreases every 2 seconds. To enable the fast increase and decrease function again, press and hold the up arrow button, press and release the select button, and then release the up arrow button.

What to do next

After you create the clustered system on the front panel with the correct IP address format, you can finish the system configuration by accessing the management GUI, completing the creation of the system, and adding nodes to the system.

Before you access the management GUI, you must ensure that your web browser is supported and has the appropriate settings enabled.

To access the management GUI, point your supported browser to the management IP address.

The list of supported web browsers is included in the interoperability information on the product support website. The interoperability information includes supported hardware, device drivers, firmware, and recommended software to ensure that your configuration is running at an optimal level.
