Installing and managing software with detached WPARs

If a system has detached WPARs (WPARs which have separately installed writable /usr files), the system software must remain compatible between the global environment and the detached WPARs.

You can use the inuwpar command to perform an installation in a global environment. After that installation is complete, the installation continues in all of the detached system WPARs or a specified set of detached system WPARs. If the -G flag is specified, the installation is first attempted in the global environment. If the installation succeeds, the installation is attempted in sequence on each of the specified WPARs.

For the inuwpar command to be successful, any installation device used for the command must be available in the WPAR. For the best results, ensure that the installation device is in a directory on a local file system in the global environment. The inuwpar command attempts to mount the installation device into the WPAR file systems and repeat the operation. If the installation device cannot be mounted, the operation on that WPAR fails, and the installation proceeds to the next WPAR. Block and character devices cannot be used as the installation device for inuwpar operations. If the file system is remote, it must be accessible to each WPAR.

If the installation directory is already accessible to the WPARs, the following options prevent the inuwpar command from attempting to remount the device into the WPAR:
  • Use the -d flag to specify the installation directory.
  • If the installation device has the same path within the WPAR as in the global environment, us the -D flag.
