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.
The HMC Classic interface is not supported in Hardware Management Console (HMC) Version 8.7.0, or later. The functions that were previously available in the HMC Classic interface are now available in the HMC Enhanced+ interface.
For more information about activating the Virtual I/O Server (VIOS) when the HMC is at version 8.7.0, or later, see Activating Virtual I/O Servers.
To migrate the Virtual I/O Server from a DVD, follow these
steps:
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:
- Log on to the Virtual I/O Server as padmin user.
- Complete the following command: $ motd -overwrite "<enter previous banner message>"
- Start any previously running daemons, such as FTP and Telnet.
- 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.
