Migrating the Virtual I/O Server from DVD

Find instructions for migrating the Virtual I/O Server (VIOS) from a DVD device that is attached to the VIOS logical partition.

Before you start, ensure that you meet the following requirements:
  • An HMC is attached to the managed system.
  • A DVD optical device is assigned to the Virtual I/O Server logical partition.
  • The Virtual I/O Server migration installation media is required.
    Note: The Virtual I/O Server migration installation media is separate from the Virtual I/O Server installation media.
  • The Virtual I/O Server is currently at Version 1.3, or later.
  • The root volume group (rootvg) has been assigned to the Virtual I/O Server
  • Use the startnetsvc command to note what services you have started for the Virtual I/O Server.
  • Determine the services and agents that are configured (by using the cfgsvc command) for use with the Virtual I/O Server. Use the lssvc command to display a list of all agents. Use the lssvc with the agent name parameter (lssvc <agent_name> to display information for a specified agent.
    Note: If any parameters have been set for an agent or service, you will need to reconfigure the parameters after you complete the migration process.
  • Back up the mksysb image before migrating the Virtual I/O Server. Run the backupios command and save the mksysb image to a safe location.
Note: If you are using an Integrated Virtualization Manager (IVM) environment, see Migrating the Virtual I/O Server from DVD when using the Integrated Virtualization Manager.
To migrate the Virtual I/O Server from a DVD, follow these steps:
  1. Activate the Virtual I/O Server logical partition using the HMC, Version 7 (or later):
    1. Insert the Virtual I/O Server migration DVD into the DVD drive assigned to the Virtual I/O Server logical partition.
    2. In the HMC navigation area, expand Systems Management > Servers.
    3. Select the server on which the Virtual I/O Server logical partition is located.
    4. In the contents area, select the Virtual I/O Server logical partition.
    5. Click Tasks > Operations > Activate. The Activate Partition menu opens with a selection of logical partition profiles. Ensure that the correct profile is highlighted.
    6. Select Open a terminal window or console session to open a virtual terminal (vterm) window.
    7. Click Advanced to open the advanced options menu.
    8. For the boot mode, select SMS.
    9. Click OK to close the advanced options menu.
    10. Click OK. A virtual terminal window opens for the logical partition.
  2. Select the boot device:
    1. Select Select Boot Options and press Enter.
    2. Select Select Install/Boot Device and press Enter.
    3. Select CD/DVD and press Enter.
    4. Select the device number that corresponds to the DVD and press Enter. You can also select List all devices and select the device number from a list and press Enter.
    5. Select Normal mode boot.
    6. Select Yes to exit SMS.
  3. Install the Virtual I/O Server:
    1. Select the desired console and press Enter.
    2. Select a language for the BOS menus and press Enter.
    3. Select Start Install Now with Default Settings and press Enter. You can also verify the installation and system settings by typing 2 to select Change/Show Installation Settings and Install.
      Note: You should not have to change installation settings simply to select the migration installation method. If a previous version of the operating system exists, the installation method defaults to migration.
    4. Select Continue with Install. The system will reboot after the installation is complete.
After the migration is complete, the Virtual I/O Server logical partition is restarted to its preserved configuration prior to the migration installation. It is recommended that you perform the following tasks:
  • Verify that migration was successful by checking the results of the installp command and by running the ioslevel command. The results of the ioslevel command indicate the ioslevel is now $ ioslevel 2.1.0.0.
  • Restart previously running daemons and agents:
    1. Log on to the Virtual I/O Server as padmin user.
    2. Complete the following command: $ motd -overwrite "<enter previous banner message>"
    3. Start any previously running daemons, such as FTP and Telnet.
    4. Start any previously running agents, such as ituam.
  • Check for updates to the Virtual I/O Server. For instructions, see the Fix Central website.
    Remember: The Virtual I/O Server migration media is separate from the Virtual I/O Server installation media. Do not use the installation media for updates after you perform a migration. It does not contain updates and you will lose your current configuration. Only apply updates using the instructions from the Virtual I/O Server Support for Power Systems™ Web site.
Note: As an alternative to the HMC, you can use the IBM® Systems Director Management Console (SDMC) to migrate the VIOS from a DVD device that is attached to the VIOS logical partition.
