NOTE: In the above command, <DX-CSN-UM-3.0.0.tar.gz> is an example of the name of an update
package. The name of the package will change as the version number changes.
The progress information is displayed on the console as the update is executed.
After all updates are complete, a message is displayed on the console if an updated component requires a restart.
NOTE: The system does not restart automatically, although the system is unusable until the restart.
Receiving System Software Update Notifications
Dell technical update subscriptions allow you to receive critical product alerts, updates to files, drivers, and utilities for
your system.
To register for these notifications:
1.
Go to dell.com/support/downloads.
2.
Click on the Technical Subscriptions link under the Drivers and Downloads section.
If a component installed on your system is newer than the component contained within the payload, the UM halts
and a message similar to the following is displayed:
Update Manager has determined that one or more component(s) in the
appliance require a downgrade. Run the Update Manager with one of the
following arguments:
-forcedowngrade" or "-skipdowngrade" to continue.
In this case, download the latest UM payload from dell.com/support before continuing. For more information on
managing downgrade scenarios, see
Downgrading A Payload
If a new payload is not available on the Dell support site, or you want to proceed after a downgrade is halted, the UM
can be re-run with one of the following options:
•
-skipdowngrade — The UM ignores the newer component and executes the upgrade.
•
-forcedowngrade — The UM attempts to downgrade the component.
CAUTION: All components do not support downgrades. Use -forcedowngrade only under the guidance of Dell
Support.
Troubleshooting Update Failures
If an update fails, the system may be in an unusable state. For information on which component update(s) failed, see
the /var/log/update.log. In most cases, running the update once again recovers the system from this state.
NOTE: The logs are located at /var/log/dellaum.log.
If the error persists, see

Repairing The Installed System Software
You can use the UM to repair the installed system software when you replace hardware, or if the Compatibility Manager
(CM) reports a CRITICAL status. To repair the system software, execute the UM with the following option as root:
/opt/dell/dellAUM/dellaum -noappdb –updateinstalledstack
