Using Dell Update Packages 21
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.log
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 output is appended to a file,
protecting any previous log file output from being overwritten.
Delivering DUPs to Your 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.
Using Software Distribution Applications With DUPs
Many IT organizations use internally developed or purchased software
distribution applications to remotely install and update software.
Updating Many Systems
For large environments that consist of hundreds or perhaps thousands of
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 system’s local drive.
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.
