Users Guide

NOTE: If you have updated the BIOS, power supply firmware, PERC firmware, PCIeSSD firmware,

Mellanox, Emulex firmware and driver, chipset and video drivers, Intel, QLogic and Broadcom

firmware the changes to the components take effect only after you reboot the system. On 13G

systems, the SAS expander firmware does not require a reboot.

NOTE: For a single reboot, install the ESM firmware update before the BIOS update.

NOTE: On 13G systems, the iDRAC and Lifecycle Controller has common DUP update.

Best practices for using DUPs

• Prepare repair disks before you perform any updates.

• Download the currently installed version of drivers, BIOS, and firmware, so that you have a backup

plan in case of any issues.

• Make sure that you have a backup of operating system files or system configuration files stored on a

system other than the one you are updating.

• Make sure that the updates are planned for and performed by the system administrator who knows

which applications could be affected.

• Before updating all systems, perform the upgrade on one nonessential system to test the update.

• Do not run other applications while executing DUPs.

• On a Microsoft Hyper-V virtual machine, while updating the host operating system components,

ensure that the guest operating systems are not running.

• Do not shut down the system while an update is in progress.

• Make sure that the system reboots without power interruption after performing a BIOS update.

• Do not close any terminal console windows used for performing the DUP CLI execution, while DUP

executions are in progress.
