Updating NetWorker by using Client Push 53
Updating from a previous release
Preparing the Media Kit Location
During a client push operation, the NetWorker server obtains the source NetWorker
software packages from the software repository, located on the NetWorker server then
pushes the software to the target host.
The Media Kit Location contains the source NetWorker 8.1 software packages used to
update the NetWorker target hosts. The Media Kit Location can be the NetWorker software
DVD or a directory that contains the extracted software packages.
If you will place multiple versions of the NetWorker software in the Media Kit Location,
create separate subdirectories for each version to avoid overwriting files and directories.
Each extracted package for each NetWorker version has an identical directory structure
and the same filenames.
There are two different scenarios to consider when preparing the software repository to
update the NetWorker software using client push:
◆ “The NetWorker server is the same operating system as the target hosts” on page 53
◆ “The NetWorker server and target host operating systems differ” on page 53
The NetWorker server is the same operating system as the target hosts
When the targets hosts are the same operating system as the server, extract each software
packages to the Media Kit Location. The Media Kit Location must reside on a file system
that is local to the NetWorker server.
The NetWorker server and target host operating systems differ
When the operating system of the target hosts differs from the NetWorker server, for
example, when a Windows NetWorker server updates a UNIX client, you must configure a
proxy host to store the cross platform packages.
The Proxy Media Kit Location is the directory on the proxy host that contains the cross
platform software packages.
Follow these guidelines when configuring a proxy host:
◆ Use the same platform as the cross platform packages.
For example, if the NetWorker server is a Linux host, use a Windows proxy host to
update Windows x86, Windows x64, and Windows ia64 clients.
◆ Install the NetWorker 7.6 or later client software.
◆ Create a client instance for the host on the NetWorker server.
◆ Create a media kit location that resides on a local file system and uses a path that
does not contain spaces.
◆ The Proxy Media Kit Location should be locally available on the proxy host.
◆ Ensure that the NetWorker packages in the Proxy Media Kit Location are the same
version as the packages in the Media Kit Location on the NetWorker server. When the
packages differ, the update process indicates that the client software will be updated
to the version that is in the NetWorker server Media Kit Location but the client is
updated to the version in the Proxy Media Kit location.
