16 Using Dell Update Packages
Interactive Mode
In the interactive mode, you issue a command, and the interface prompts
you for permission to continue executing the command. When you execute
a package interactively, it first displays a scrollable view of the release notes for
the package. You may view these notes before continuing with the execution of
the package.
The DUP may be executed from a local console attached to the target system
or from an administrator’s workstation by using a remote shell, such as ssh.
Once a package has been delivered to the target system, administrators can
execute the package in its simplest form by typing ./packagename.bin from the
working directory, where packagename is the model and component
-specific
name of the package. This syntax assumes that the .bin file has the
appropriate permissions set and that a user account with root privileges
executes the update. Once underway, the DUP will echo its progress and
status to the console (stdout) and log its activity to /var/log/messages.
Non-Interactive Mode
Non-interactive mode is essential when executing a script for applying DUPs
to multiple systems. When applying DUPs to multiple systems, you cannot
answer yes or no during script execution. Your script specifies -q for
non
-interactive mode; often script writers add -f for force and -r for reboot if
a reboot is required for the type of update being performed.
In the following command example, the command applies a BIOS DUP
without any user confirmation, forces the execution in the case of a
downgrade from a more recent BIOS version, and reboots the system after the
DUP is applied. This command is executed provided the DUP satisfies all the
system and version requirements.
./PE2850-ESM_FRMW_LX_R92394.bin -q -f -r
