Restoring the Virtual I/O Server from the HMC by using a nim_resources.tar file

You can restore the Virtual I/O Server (VIOS) base code, applied fix packs, custom device drivers to support disk subsystems, and some user-defined metadata from a nim_resources.tar image stored in a remote file system.

About this task

To restore the Virtual I/O Server from a nim_resources.tar image in a file system, complete the following steps:

Procedure

  1. Run the installios command from the HMC command line.
    This restores a backup image, nim_resources.tar, that was created by using the backupios command.
  2. Follow the installation procedures according to the system prompts. The source of the installation images is the exported directory from the backup procedure. For example, server1:/export/ios_backup.
  3. When the restoration is finished, open a virtual terminal connection (for example, by using telnet) to the Virtual I/O Server that you restored. Some additional user input might be required.
  4. If you restored the Virtual I/O Server to a different system from which it was backed up, you must restore the user-defined virtual devices.
