If the device is part of a cluster solution, verify that the latest level ofcode is supported for the cluster solution before you update the code.If the server firmware has become corrupted, such as from a power failure duringan update, you can recover the server firmware in the following way:v In-band method: Recover server firmware, using either the boot block jumper(Automated Boot Recovery) and a server Firmware Update Package ServicePack.v Out-of-band method: Use the IMM web interface to update the firmware, usingthe latest server firmware update package.Note: You can obtain a server update package from one of the following sources:v Download the server firmware update from the World Wide Web.v Contact your IBM service representative.To download the server firmware update package from the World Wide Web, go tohttp://www.ibm.com/supportportal/.The flash memory of the server consists of a primary bank and a back up bank.You must maintain a bootable UEFI firmware image in the back up bank. If theserver firmware in the primary bank becomes corrupted, you can either manuallyboot the back up bank with the UEFI boot backup jumper (J15), or in the case ofimage corruption, this will occur automatically with the Automated Boot Recoveryfunction.In-band manual recovery methodThis section details the in-band manual recovery method.About this taskTo recover the server firmware and restore the server operation to the primarybank, complete the following steps:Procedure1. Read the safety information that begins on “Safety” on page vii and“Installation guidelines” on page 283.2. Turn off the server, and disconnect all power cords and external cables.3. Remove the cover (see “Removing the top cover” on page 146).4. Locate the UEFI boot backup jumper (J15) on the system board.Chapter 3. Troubleshooting 117
