Remote Update
Remote update, also known as out-of-band update or operating system-
independent platform update, allows you to update the system independent
of the state of the operating system or the power on/off state.
Benefits of Remote Update
With Operating System independent platform update, an operating system
need not be running on the system. Multiple updates can be scheduled
together along with a graceful or power-cycle reboot into USC to perform the
updates. Although the updates may involve intermediate BIOS restarts,
Lifecycle Controller will automatically handle them until the updates are
complete.
This feature supports two methods to perform updates:
• Install from Uniform Resource Identifier (URI): This method allows a
WS-MAN request to install or update software on a host platform using a
URI. The URI consists of a string of characters used to identify or name a
resource on the network. The URI is used to specify the location of the
Dell Update Package image on the network that can be downloaded to the
Lifecycle Controller and then installed.
•
Install from Software Identity: This method allows update or rollback to a
version that is already available on the Lifecycle Controller.
You can use a WS-MAN capable application, script or command line utility to
perform a remote update. The application or script performs WS-MAN
invoke method request using one of the remote update interface methods.
The iDRAC then downloads the firmware from the network share (local
network share, CIFS, NFS, FTP, TFTP, http, https) URI and stages the
updates to be performed at the specified time and utilizing the specified
graceful, power cycle or none system reboot types.
Important
• When you perform a remote update on the Driver Pack for the system it
will replace the current driver pack. The replaced driver pack will no longer
be available.
