24 Using Dell Update Packages
Specifying the Order of Multiple Updates
When applying multiple updates at the same time, be sure to use the order
indicated in "Installation Order of DUPs." As previously noted in "System
Reboot Required," you may defer rebooting the system until after running the
last of multiple DUPs.
Saving Console Output
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.
The following are two example commands that redirect output to a log file:
./PE2600-BIOS-LX-A01.bin | tee -a /var/bioslogs.log
./PE2600-BIOS-LX-A01.bin -q | tee -a
/var/bioslogs.log
If you run these commands in the order shown above, the first command
directs its interactive mode output to be appended to the log file. The second
command directs its non
-interactive mode output to be appended to the end
of the same log file.
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.
