Saving Console Output for Linux

As the DUPs are executed, messages are printed to the console. To redirect console output, use the following syntax with

interactive commands:

./packagename.bin|tee -a logname.lo

The |tee specifies the output from the DUP to be sent to both the console and to a log file. The ‑a switch ensures that the output is

appended to a file, protecting any previous log file output from being overwritten.

Delivering DUPs to the Systems

The DUP application does not provide scheduling and delivery of the packages to multiple systems. You must rely on third‑party or

native operating system applications to accomplish script execution and distribution on multiple systems.

Updating Multiple Systems

For large environments that consists of multiple systems, remote software distribution applications provide the best solution. Many

of these tools can effectively leverage the DUP and provide the convenience of installing and updating a variety of software, such

as operating systems and applications, in a heterogeneous environment.

Network file shares also are an effective method of making DUP accessible in a distributed environment. When a DUP begins

execution, it first copies the contents of the package to a temporary location on the local drive of the system. This process ensures

that the update can be completed even if the connection to the network share is lost for any reason.

Remote Terminal Sessions

In today's highly distributed environment, it is common for IT organizations to use remote access solutions, such as Microsoft

Terminal Services, to gain access to their remote systems. You may use this type of solution to run DUPs.

NOTE: If the terminal session is disconnected during a NIC driver update, you will need to re-connect and verify that the

update has completed successfully.

Stand-Alone Systems and Firewalls

For systems that are not connected to the Internet or that have firewall which block user downloads, you need to download DUP

from dell.com/support by using a system that has Internet access, such as desktop or portable computer. You can make DUP

available to the system by copying them onto removable media that the system supports.

Confirming the Update

To ensure that the DUPs were applied to the system, review the console output that was generated during execution. For detailed

information about the messages, see Linux Troubleshooting.

If you want to revert to a previous (older) version of the software after updating to a newer version, you must download the

appropriate DUP from dell.com/support/manuals and install it.

For Systems Running Linux:

To install the previous version from a script, use -q (unattended) mode. In addition, you must use the CLI -f option, which forces the

downgrade.

NOTE: If the system loses power during the update process, you must perform the updates again.
