Updating firmware using DUP

Before you update firmware using Dell Update Package (DUP), make sure to:
  • Install and enable the IPMI and managed system drivers.
  • Enable and start the Windows Management Instrumentation (WMI) service if your system is running Windows operating system,
    NOTE While updating the iDRAC firmware using the DUP utility in Linux, if you see error messages such as usb 5-2: device descriptor read/64, error -71 displayed on the console, ignore them.
  • If the system has ESX hypervisor installed, then for the DUP file to run, make sure that the "usbarbitrator" service is stopped using command: service usbarbitrator stop

Some versions of DUPs are constructed in ways that conflict with each other. This happens over time as new versions of the software are created. A newer version of software may drop support for legacy devices. Support for new devices may be added. Consider, for example, the two DUPs Network_Firmware_NDT09_WN64_21.60.5.EXE and Network_Firmware_8J1P7_WN64_21.60.27.50.EXE. The devices supported by these DUPs fit into three groups.

  • Group A are legacy devices supported only by NDT09.
  • Group B are devices supported by both NDT09 and 8J1P7.
  • Group C are new devices supported only by 8J1P7.

Consider a server that has one or more devices from each of Groups A, B, and C. If the DUPs are used one at a time they should be successful. Using NDT09 by itself updates the devices in group A and group B. Using 8J1P7 by itself updates devices in group B and group C. However, if you try to use both DUPs at the same time that may attempt to create two updates for the Group B devices at the same time. That may fail with a valid error: "Job for this device is already present". The update software is unable to resolve the conflict of two valid DUPs attempting two valid updates on the same devices at the same time. At the same time both DUPs are required to support Group A and Group C devices. The conflict extends to performing rollbacks on the devices too. For best practice it is suggested to use each DUP individually.

To update iDRAC using DUP:

  1. Download the DUP based on the installed operating system and run it on the managed system.
  2. Run the DUP.
    The firmware is updated. A system restart is not required after firmware update is complete.
