7.1.4 Firmware upgrade

Upgrading the firmware of NeXtScale System servers uses the same tools as

System x servers. The following tools are available to update the firmware of the

IBM NeXtScale nx360 M4 compute node, such as UEFI, IMM, or drivers:

򐂰 Stand-alone updates

Firmware updates can be performed online and offline. Offline updates are

released in a bootable diskette (.img) or CD-ROM (.iso) format. Online

updates are released for Windows (.exe), Linux, and VMware (.sh). The

online updates are run under from the command line. They are scriptable, and

are provided with XML metafiles for use with UpdateXpress system packs.

Updates are available as Windows (.exe) or Linux (.bin) files, and are applied

inband or remotely through the IMM.

򐂰 UpdateXpress System Packs

UpdateXpress System Packs are a tested set of online updates that are

released together as a downloadable package when products are first made

available, and quarterly thereafter. The UpdateXpress System Packs are

unique to each model of server.

The latest version of UXSP and a user’s guide are available from this website:

򐂰 Bootable Media Creator

IBM released a tool that is called Bootable Media Creator with which you can

bundle multiple System x updates from UpdateXpress System Packs and

create a single bootable media (such as CD/DVD, USB flash drive, or a file set

for PXE boot). You can download the tool from this website:
