Migrating your network setup
You might need to migrate your network setup to use RoCE Express or to adapt an existing RoCE Express setup to a changed environment.
Attention: Migrating a network setup can be risky, especially if you are migrating the
setup for the only connection to a Linux® instance. You might not be able to use an inadequately migrated interface to connect to your
Linux instance for corrective actions.
To mitigate against potential lockouts, set up and test an alternative connection to your Linux instance before you begin the migration. For example, use HiperSockets and a separate IP subnet for an alternative connection without any physical components. Once set up, verify that your alternative connection persists across reboots before you proceed to migrate your network setup.
You can resort to the Linux console to restore
regular connectivity.
- Linux as a KVM guest
- Access the virtual console from the host or use virt-manager.
- Linux as a z/VM® guest
- Access the console through a 3270 terminal emulation.
- Linux in LPAR or DPM partition mode
- Access the console through the Operating System Messages applet or through the Integrated ASCII Console applet on the HMC.
