Before you begin

About this task

You can add, delete, or change subnets to all nodes on the Admin Network Subnet List.

Steps

  1. From the service laptop, log in to the primary Admin Node:
    1. Enter the following command: ssh admin@primary_Admin_Node_IP
    2. Enter the password listed in the Passwords.txt file.
    3. Enter the following command to switch to root: su -
    4. Enter the password listed in the Passwords.txt file.
      When you are logged in as root, the prompt changes from $ to #.
  2. Start the Change IP tool by entering the following command: change-ip
  3. Enter the provisioning passphrase at the prompt.
    The main menu screen appears.

  4. Optionally limit the networks/nodes on which operations are performed. Choose one of the following:
    • Select the nodes to edit by choosing 1, if you want to filter on specific nodes on which to perform the operation. Select one of the following options:
      • 1: Single node (select by name)
      • 2: Single node (select by site, then by name)
      • 3: Single node (select by current IP)
      • 4: All nodes at a site
      • 5: All nodes in the grid
      • 0: Go back
    • Allow “all” to remain selected.
    After the selection is made, the main menu screen appears. The Selected nodes field reflects your new selection, and now all operations selected will only be performed on this item.
  5. On the main menu, select the option to edit subnets for the Admin Network (option 3).
  6. Choose one of the following:
    • Add a subnet by entering this command: add CIDR
    • Delete a subnet by entering this command: del CIDR
    • Set the list of subnets by entering this command: set CIDR
      Note: For all commands, you can enter multiple addresses using this format: add CIDR, CIDR

      Example: add 172.14.0.0/16, 172.15.0.0/16, 172.16.0.0/16

      Tip: You can reduce the amount of typing required by using “up arrow” to recall previously typed values to the current input prompt, and then edit them if necessary.

  7. When ready, enter q to go back to the main menu screen. Your changes are held until cleared or applied.
    Note: If you selected any of the "all" node selection modes in step 2, you must press Enter (without q) to get to the next node in the list.
  8. Choose one of the following:
    • Select option 5 to show edits in output that is isolated to show only the changed item. Changes are highlighted in green (additions) or red (deletions), as shown in the sample output below:

    • Select option 6 to show edits in output that displays the full configuration. Changes are highlighted in green (additions) or red (deletions).
    Note: Certain terminal emulators might show additions and deletions using strikethrough formatting.
  9. Select option 7 to validate all staged changes.
  10. Optionally select option 8 to save all staged changes and return later to continue making changes. This option allows you to quit the Change IP tool and start it again later, without losing any unapplied changes.
  11. Do one of the following:
    • Select option 9 if you want to clear all changes without saving or applying the new network configuration.
    • Select option 10 if you are ready to apply changes and provision the new network configuration. During provisioning, the output displays the status as updates are applied as shown in the following sample output:
      Generating new grid networking description file...
      Running provisioning...
      Updating grid network configuration on Name
  12. After successfully applying the changes, download the new provisioning repository by accessing the new package on the Maintenance > Recovery Package page.
